Rodent Control in Winter in the UAE: What Actually Changes

Rodent control in winter in the UAE is the same job as rodent control in July, because rats and mice in Dubai and Abu Dhabi stay active all year. The cooler months change less than most seasonal advice suggests. Nights get cool enough that some movement indoors is plausible, homes open up, gardens get busier, and a house with the air conditioning off is quiet enough to hear a rat in the false ceiling. The fix is the same in any month: identify which rodent you have, close the gaps it uses with materials it cannot chew, and trap or bait in a way that keeps the bait out of reach of children and pets.

Three rodents share UAE cities with people: the house mouse (Mus musculus), the black or roof rat (Rattus rattus) and the brown or Norway rat (Rattus norvegicus). Each one lives at a different level of a building, so the species decides where the search starts.

An earlier version of this page said that rodent sightings in villas rise sharply from January to March and that gnawed wiring is a leading cause of short circuits in villas. We could not find a published source for either statement, so both have gone. In their place is what the published science says about these three species, what a UAE winter looks like on the thermometer, and what that means for a villa or an apartment.

At GRMC Pest Control, we plan rodent work in Dubai and Abu Dhabi around the building, because the gap a rat uses in January is usually the one it used in August.

This guide to rodent control in winter in the UAE covers which rodents live in homes here, whether the season really matters, the signs to look for, the entry points in villas and towers, why a box of supermarket poison so often fails, and what a professional programme should include.

Rodent control in winter in the UAE, in short

Before the detail, the whole picture in seven points.

• Rodents here are a year-round problem: the University of California’s rat guidance tells homeowners to check for signs periodically “because rats are active throughout the year”, and a UAE winter gives no reason to assume otherwise.
• A winter surge has never been measured here: cooler nights make some movement indoors plausible, but we found no published UAE data showing that rodent activity rises between January and March.
• What the season does change is the household: doors stand open, gardens are replanted and used, and a quiet house makes an animal in the ceiling audible.
• The species tells you where to look: mice stay close to food indoors, roof rats live high in ceilings and garden vegetation, and Norway rats live low around foundations, bins and ground floors.
• Droppings are the fastest identification: their size and shape separate the three species, and where you find them narrows it further.
• The gaps are small: the US Centers for Disease Control and Prevention says a mouse can fit through a hole the width of a pencil, about 6 mm.
• Poison on its own tends to fail: rats avoid new objects for days or weeks, and the gaps they came through stay open. Proofing, trapping and secured bait stations, followed up over several visits, is the approach that deals with the cause.

Which rodents live in Dubai and Abu Dhabi homes

The UAE has its own desert rodents, but they are not the animals in your kitchen. A 2023 study in the journal Viruses by Weidinger and colleagues lists Cheesman’s gerbil, the Balochistan gerbil, Sundevall’s jird and the Arabian spiny mouse as the typical wild rodents of the Dubai Desert Conservation Reserve, and those are desert animals. The three that share buildings with people arrived with people. Jacky Judas, in the chapter on terrestrial mammals in A Natural History of the Emirates (Springer Nature, 2023), writes that “the presence of mice and rats is probably as old as human civilization”, and describes them arriving by trade routes and ships.

The house mouse

The house mouse, Mus musculus, is the rodent most people meet first. Judas describes it as “present in nearly all human settlements, from city centres to villages”. The same Weidinger study records ten house mice trapped during pest control at an animal food store inside the Dubai reserve, which fits the species’ habit of living wherever people keep food.

The University of California Statewide IPM Program (UC IPM) puts an adult at about half an ounce, roughly 14 grams, and 5 to 7 inches long including a 3 to 4 inch tail, which is about 13 to 18 cm from nose to tail tip. Two other details from the same guidance matter more than size. House mice “seldom venture more than 30 feet from their nest sites and food supply”, about nine metres, so a mouse seen in your kitchen is very likely nesting within a few metres of where you saw it, often in the void behind the kickboards under the units or behind an appliance.

The second detail is how little space a mouse needs. UC IPM states that house mice “can squeeze under gaps ¼ inch tall, and through openings 3/8 inch wide”, about 6 mm and 10 mm. A gap under a kitchen door that you would not notice is wide enough.

The black rat, or roof rat

The black rat, Rattus rattus, is the climber, and it is the one most often behind noises in a ceiling. Judas calls it “probably the most widespread, living in cities, gardens, parks”, while noting that for both rat species in the UAE “their respective status and distribution is not well known”. Nobody has published a census of which rat lives in which Dubai or Abu Dhabi building, and we will not pretend otherwise.

UC IPM’s rat guidance describes roof rats as “agile climbers” that “usually live and nest aboveground in shrubs, trees, or dense vegetation”, and that indoors choose “enclosed and elevated spaces, such as attics, wall voids, ceiling voids, and cabinets”. They are seen at night running along overhead utility lines or fence tops, they “routinely travel up to 300 feet or more for food”, roughly 90 metres, and they prefer fruit. UC IPM puts their weight at 5 to 10 ounces, about 140 to 280 grams, which makes them the lighter of the two rats.

Translate that into a UAE villa and you get palms, bougainvillea and creepers against the boundary wall, the top of that wall used as a runway, cable runs and pipework on the facade, and a false ceiling in place of the attic that most UAE villas do not have. In a tower, the equivalents are the ceiling voids above corridors and apartments and the service shafts that connect one floor to the next.

The brown rat, or Norway rat

The brown or Norway rat, Rattus norvegicus, is the heavier, ground-level species. Judas describes it as “a larger species, more heavily built, that might prefer wide open spaces”. UC IPM gives its weight as 7 to 18 ounces, about 200 to 510 grams, and calls it a “burrowing rodent” whose burrows “may be found along building foundations, beneath rubbish or woodpiles, and around gardens and fields”. Indoors it tends to “dwell in the basement and ground floor areas”.

In UAE terms that points to bin stores and refuse rooms, ground-floor units, basement car parks, irrigated garden beds and the ground along the foundations of a villa. So a roof rat problem is traced from the ceiling and the garden canopy downwards, and a Norway rat problem from the bins, drains and foundations upwards. Droppings are usually the quickest way to tell which one you have, as the signs section below explains.

Does winter really bring rats indoors in the UAE?

Most seasonal rodent advice is built on this idea, so it is worth checking against the evidence.

Where the winter idea comes from

The idea is sound in its original setting. UC IPM’s house mouse guidance states that “where outdoor populations of house mice exist, they frequently enter homes in autumn when nighttime temperatures become colder”. That is written for California. Advice written for North America and Europe carries the same seasonal logic, and it has been copied into markets where the seasons behave differently.

What a UAE winter looks like on the thermometer

The National Center of Meteorology’s January climate summary, as reported by Emirates 24|7 on 1 January 2025, gives a national mean temperature for January of 18.3°C and a mean minimum air temperature in the range of 11.6°C to 15.2°C. Those are cool nights by UAE standards, and cool enough that some movement of mice into buildings, of the kind UC IPM describes, is plausible here too.

What we could not find is any measurement of it. We found no published UAE study, and no figure from Dubai Municipality or the Abu Dhabi Public Health Centre, showing that rodent activity or complaints rise between January and March. Pest control websites in this market repeat the winter claim, but none that we have seen cites anything for it. You will also read the opposite claim, that the summer heat drives rodents indoors in search of water and shade. That is equally plausible, and we have found no data for it either.

Rats and mice are active here all year, UC IPM’s advice to keep checking for rats year-round applies, and a winter in which the NCM puts the January mean minimum between 11.6°C and 15.2°C gives no reason to treat rodents here as a seasonal problem.

What the cooler months genuinely change in a UAE home

Several things do change between the autumn and the spring, and most of them are about how people use the house.

The air conditioning runs less, and often not at all overnight. A villa that hums through the summer goes quiet in January, and an animal moving across a gypsum ceiling panel becomes audible for the first time. In our reading, some of what gets reported as a winter arrival is a resident finally hearing an animal that was already living there.

Doors and windows open. Sliding doors to the garden and the balcony stand open for hours, the kitchen door to the service yard gets propped, and the majlis door stays open while guests come and go. UC IPM notes that rats of either species, “especially young rats, can squeeze beneath a door with only a 1/2-inch gap”, which is about 13 mm, and a door left open for an evening needs no gap at all.

The garden gets busier. The cooler months are when many villa gardens are replanted and when families eat, barbecue and entertain outdoors. Several of the signs UC IPM lists for rats around a home are garden signs: rat droppings around pet food containers, burrows beneath bins and compost piles or among garden plants, and gnawing on fruit that is on or falling from the trees. More food outside, more digging and more irrigation give a resident rodent more to work with.

And it is the comfortable season for proofing work. Opening up a false ceiling, working along a roofline, cutting palms and creepers back from the walls or re-screening vents is easier and more thorough in January than in August. If you are going to deal with the structure of the problem, the cooler months are the time to do it, which is the one genuinely seasonal argument this page can make.

Signs of rats and mice in a villa or apartment

UC IPM notes that rats are “mostly active at night”, so most rodent problems are found through what the animals leave behind.

Droppings: the quickest way to tell which one you have

The sizes below come from the Internet Center for Wildlife Damage Management’s species pages, converted to millimetres. Where you find the droppings narrows it down further.

• House mouse: droppings “average ¼ inch long”, about 6 mm. Typically found in kitchen drawers, cupboards, behind the cooker and along the kickboards under the units.
• Roof rat: droppings “about 1/2 inch long with pointed ends”, about 13 mm. Typically found on top of false ceiling panels, along cable trays, on top of boundary walls and in storerooms.
• Norway rat: droppings that “may be as large as ¾ inch long and ¼ inch in diameter with blunt ends”, about 19 mm by 6 mm. Typically found in bin stores, garages and along the base of outside walls.

In a UAE kitchen the confusion is usually between mouse droppings and cockroach droppings. ICWDM’s house mouse page notes that cockroach droppings are smaller and, under magnification, show “distinct longitudinal ridges and squared-off ends”. A phone camera on full zoom may be enough to see the difference.

Other signs worth checking

• Noise overhead: UC IPM lists “noises coming from the attic or drop ceilings” as a sign of rats. In a UAE home that means the false ceiling, most often at night.
• Smudge marks: UC IPM describes “smudge marks caused by the rats rubbing their fur against beams, rafters, pipes, and walls”. Check where pipework enters the kitchen, along cable trays and around the edge of the ceiling access hatch.
• Gnawing: fresh gnaw marks on doors, cables, plastic pipework and food packaging, and on fruit in the garden.
• Nests: UC IPM says mouse nests are “made from finely shredded paper or other fibrous material”. Look in storerooms, under sinks and in the backs of cupboards that are rarely opened.
• Smell: “a musky odor is commonly associated with mice”, according to UC IPM, and it is often noticed first in a closed cupboard.
• Runways and burrows outside: UC IPM lists rats travelling along utility lines or fence tops at dusk, and burrows beneath bins and compost or among garden plants. In a villa, that means the top of the boundary wall and the soil along it.
• Your car: UC IPM notes that rats “commonly gnaw on the insulative sheaths of engine wires in cars”. If a car parked in the driveway or carport develops an electrical fault, check the engine bay for nesting material and droppings.

Cleaning up droppings safely

Resist the urge to sweep or vacuum. The CDC’s clean-up guidance is direct: “Don’t vacuum or sweep rodent urine, droppings, or nesting materials. This can cause tiny droplets containing viruses to get into the air.”

The CDC method for a home starts before any cleaning: open all doors and windows for 30 minutes to ventilate the space, and leave the area during that time. Then put on rubber or plastic gloves, spray the droppings and urine with a bleach solution of 1 part bleach to 9 parts water, or a registered disinfectant, “until very wet”, leave it to soak for five minutes or as long as the disinfectant label says, wipe it up with paper towels, and wash your hands after removing the gloves. If you are booking an inspection, photograph the droppings where you found them before you clean, because their size and location are the evidence a technician needs.

Health risks, and what gnawed wiring actually means

Rodents in a home raise two separate concerns: disease, and damage to wiring and pipework.

The CDC’s rodent control guidance lists diseases that rodents spread directly, including leptospirosis, rat-bite fever, salmonellosis and hantavirus, through breathing in contaminated air, touching contaminated materials or bites. UC IPM names “typhus, leptospirosis, food borne illnesses (caused by pathogens such as salmonella, E. coli, and campylobacter), and rat bite fever” as the most common rat-transmitted diseases. Neither source is describing the UAE specifically, and we are not aware of published data on how often these infections are picked up from rodents here, so we will not put a number on the risk. The practical point stands without one: droppings and urine on food surfaces and in cupboards are a hygiene problem, which is why the clean-up method above matters.

On wiring, UC IPM says that roof rats living in the roof space of a home “may cause considerable damage and present safety concerns (electrical sparks and fires) due to their gnawing and nest-building activities”. It also notes that rats can chew through plastic, foam, wood and caulk, which covers the foam insulation around AC pipework and the plastic conduit in a ceiling void.

We found no data on how often rodents cause electrical faults in UAE homes, so the sensible response is practical: if a circuit keeps tripping and you have also heard movement in the ceiling, have an electrician look at the cabling in the void as well as a pest control technician.

How rodents get into UAE villas and towers

The CDC’s guidance on sealing a home starts with scale: “Mice can fit through a hole the width of a pencil (1/4 inch or 6 millimeters in diameter).” UC IPM’s advice for keeping out both rats and mice is to seal “all holes larger than 1/4 inch”. Every entry point below is judged against that 6 mm, which is far smaller than most people expect.

Villas

• Doors to the outside: garage doors, the kitchen door to the service yard and the majlis door. UC IPM recommends door sweeps or weather stripping and exterior doors “sealed at the threshold”, and notes that double doors also need sealing at the gap where the two leaves meet.
• AC and service penetrations: the holes where split-unit refrigerant lines, condensate pipes and cables pass through the wall. These are often packed with expanding foam, which UC IPM lists among the gnawable materials to avoid when mouse-proofing.
• Vents and grilles: kitchen and bathroom extracts, and any vent near ground level. UC IPM specifies 1/2-inch (13 mm) galvanised mesh for vent covers and says to “never use lightweight ‘chicken wire’, since rats can easily pass through wire openings”.
• Drains: the CDC lists floor drains among the places to check inside a home. In a villa that means the laundry and service area gullies, particularly any with a missing or broken grate.
• Vegetation touching the house: UC IPM advises removing climbing plants from buildings and cutting back branches that overhang the roof. In a UAE garden the usual culprits are palm fronds, bougainvillea and creepers trained up the walls.
• The roof: a flat villa roof carries AC outdoor units, a water tank and pipe openings. UC IPM recommends screening the tops of rooftop plumbing vent pipes more than 2 inches (about 5 cm) in diameter.

Towers and apartments

A flat above the ground floor is not out of reach. Roof rats climb, and every tower has vertical routes built into it.

• Service shafts and risers: the vertical pipe and cable routes connecting the floors, and the gaps where pipes leave the shaft and enter a kitchen or bathroom. The CDC lists pipes under sinks and electrical and utility lines among the places to check.
• False ceilings: the void above corridors and apartments holds cable trays, lighting and, in many towers, the fan coil unit that delivers district cooling or chilled water, with its condensate tray and drain line. That gives a rodent a runway and, if the drain leaks, a water source in the same enclosed space.
• Refuse chutes and bin rooms: the chute doors on each floor and the collection room at the bottom concentrate food waste for the whole building.
• Appliance voids: the holes cut behind kitchen units for dishwasher and washing machine hoses, and the ducting of the cooker hood.
• Ground and basement levels: car parks, loading bays and ground-floor food outlets, the levels where a Norway rat, as a ground-floor species, is most likely to turn up.

Because a house mouse seldom ranges far from its nest, which UC IPM puts at about 30 feet, nine metres, a mouse problem in a flat usually means a nest inside that flat or in a wall it shares. A rat in a tower is more often a building problem, since roof rats range much further. Tell building management in writing, because the shafts, chutes and common ceilings are theirs to treat and proof, and a flat treated on its own will keep meeting whatever is living in the shared spaces.

What to seal the gaps with

UC IPM recommends sealing cracks and openings larger than 1/4 inch “with steel wool, wire screen, or sheet metal” and warns that “rats can chew through plastic, foam, wood, and caulk”. The CDC suggests steel wool held in place with caulk for small holes, and lath screen or metal, cement, hardware cloth or metal sheeting for larger ones. In practice, the builder’s foam around an AC line is a temporary fix at best, and the lasting repair is metal mesh or cement with a sealant finish over it.

In a rented villa or flat, structural repairs such as re-screening vents or sealing around service penetrations usually need the landlord or building management to agree, so check your tenancy contract. A written inspection report that lists each gap, its location and the material it needs is the document to send them.

Why supermarket poison alone rarely ends a rodent problem

Buying a box of rat poison is the most common first move, and it is an understandable one. On its own it tends to fail, for reasons that are well documented.

Rats avoid anything new

UC IPM explains that rats memorise their surroundings and “quickly detect and tend to avoid new objects and new foods”, so “they often avoid traps and baits for the first several days (and maybe weeks) following the initial placement”. It adds that this neophobia “is thought to be more pronounced in roof rats than in Norway rats”, which matters here because the roof rat is the one in your ceiling.

A box of bait pushed through the ceiling hatch on Saturday and checked on Monday tells you almost nothing. A trap that snaps without catching anything is worse, because UC IPM warns that “it will be very difficult to catch the rat with a trap again”.

Poison leaves the gaps open

Even when the bait is taken, the opening around the AC line or under the kitchen door is still there, and the next mouse or rat uses it. Proofing is the part that changes the building, and it is the part retail poison leaves out.

Where the animal dies

UC IPM’s house mouse guidance recommends trapping indoors partly because it avoids the “dead house mouse odor that may result when poisoning is done within buildings”. In a UAE villa or flat, a poisoned rodent can end up in the false ceiling, a wall void or the space behind the kitchen units, where it cannot be reached without opening something up, and a closed, warm void is the worst place for it.

The risk to children, pets and wildlife

In UC IPM’s words, “All rodent baits are toxic to dogs and cats.” It adds that because anticoagulant baits are slow acting, “dead rats can contain several lethal doses of toxicant, and secondary poisoning of pets and wildlife is possible if they eat rat carcasses”, and that most pet deaths involve dogs, usually from eating the bait directly. In a villa with a dog in the garden, or in a community where cats roam between the houses, that is a real consideration.

The United States Environmental Protection Agency acted on the same risk. Its rodenticide restrictions state that second-generation anticoagulants “no longer are registered for use in products geared toward consumers” in the US, and require professional products to go in tamper-resistant bait stations wherever children under six, pets or non-target wildlife could reach the bait. That is a US rule, quoted here for the reasoning behind it, and not a description of what is sold in UAE shops.

None of this makes bait useless. Placed by a professional in secured stations where children and pets cannot reach it, and combined with proofing and trapping, it has a place. What fails is loose bait on its own, scattered with no record of where it went and with the gaps still open.

What a professional rodent control programme involves

Whoever you hire, this is the sequence to expect, and a quote that skips steps is quoting for part of the job.

• Inspection and identification: droppings, smudge marks, runways and entry points, checked from the garden and roof down to the drains and bin store, or from the ceiling void to the kitchen in a flat. The species is decided here, because it sets where everything else goes.
• A written proofing list: every gap, where it is, roughly how big it is, what it needs and who is responsible for fixing it, whether that is the owner, the tenant or building management.
• Proofing work: metal mesh and sealant around service penetrations, door sweeps, screened vents and grilles, and vegetation cut back from the walls and roof.
• Changes around the house: food and pet food in sealed containers and not left out overnight, lidded garden bins, fallen fruit collected, and clutter cleared from garages and storerooms, which UC IPM lists as places rats nest.
• Trapping indoors: UC IPM calls snap traps “the safest, most effective, and most economical way to trap rats”. Traps go along walls and known runways, and are left long enough to get past the neophobia described above.
• Secured bait stations where they are appropriate: tamper-resistant, fixed in place, numbered and marked on the report, usually around the outside of the property. Loose bait inside a home with children or pets has no place in a professional job.
• Follow-up visits: to check traps and stations, remove any carcasses, confirm that activity has stopped and check that the proofing has held.
• Clean-up: droppings and nesting material removed using the CDC method described above.

How long does it take? Nobody can give you a date on the first visit. UC IPM’s point that rats may take “several days to weeks” to enter and feed in a new bait station is the reason a rodent programme is built around follow-up visits.

Access is the practical detail people forget. In a tower or a gated community, every follow-up visit needs the same gate pass or building booking as the first one, and bait stations in a shared area need building management’s agreement, so sort both out when you book.

Our rodent control service in Dubai and Abu Dhabi starts with an inspection to identify the species and its entry points, followed by proofing.

Approvals: Dubai Municipality and ADPHC

Rodent work sits within general pest control, and the two emirates regulate it differently.

Dubai

In Dubai, pest control companies are cleared by Dubai Municipality’s Public Health Pest Control Section through a No Objection Certificate, and the Municipality publishes a list of approved companies that anyone can check. There is no public licence number to quote. GRMC appears on the August 2026 edition of that list at entry 135, in Group C, under its registered name, G R M C FOR PUBLIC HEALTH PESTS CONTROL SERVICES CO. L.L.C.

Dubai Municipality’s list defines the group letters as headcount bands of qualified pest control staff, with Group A above 25, Group B 11 to 25 and Group C 1 to 10, and they say nothing about the quality of the work. Termite work, fumigation and bird control have separate specialist listings, so a general listing is not a claim about any of those. Our guide to Dubai Municipality approved pest control shows how to run the check on any company, and our guide to choosing a pest control company in Dubai covers what else to ask.

Abu Dhabi

In Abu Dhabi the regulator is the Abu Dhabi Public Health Centre. Its own page states that “the public health pest control services have been transferred under our mandate” and that the Centre “will issue and renew work permits for all public health pest control activities”. ADPHC puts no date on that transfer, so neither do we. It publishes no public register of permitted companies, so for an Abu Dhabi job ask to see the company’s ADPHC work permit. A Dubai Municipality approval is a Dubai credential and says nothing about standing in Abu Dhabi.

ADPHC also says it will process service requests “concerning the monitoring and control of pests in residences, public areas and facilities”, reported through the TAMM platform or its helpline, 800555, which is the route to use for rodents in a public space near your home. We cover how to assess a company in an emirate with no public register in our guide to pest control companies in Abu Dhabi.

What we cannot tell you

We cannot tell you whether this winter will bring more rodents to your street. Nobody publishes that data for the UAE, and we have said so above instead of repeating a seasonal claim we cannot support.

We cannot promise that no rodent will ever get into your home again. A neighbour’s bin store, a building site next door, an open garden door on a busy evening or an untreated service shaft can all bring the next one in, and no treatment changes what happens outside the property.

And there is no rodent control price on this page. The cost depends on the size of the property, the species, how many entry points need proofing, how much of the work falls on building management, and how many follow-up visits the job needs, so there is no fair figure to give before someone has seen the property.

GRMC’s rodent control carries our 100% Pest-Free Or Money Back offer: if rodents are still active after the treatment and the follow-up visit, you get your money back. Contact GRMC Pest Control to book a rodent inspection in Dubai or Abu Dhabi, and if you have photographed the droppings, send the photos when you book so the technician arrives knowing which species to look for.
