House Geckos in UAE Homes: Are They Harmful? | Al Asfour Al Zahabi

Are house geckos harmful, and why do they gather around lights and inside UAE homes? Learn how to reduce them without poisons by sealing gaps, changing your lighting and controlling the insects they eat, and how to clean up their droppings hygienically.

The house gecko, known in Arabic as "burs", "wazagh" or "abu burais" depending on the region, is one of the creatures UAE residents see most often on house walls and around balcony lights, and many people find it unsettling or frightening. But before you look for a way to get rid of it, it helps to know that it is usually a sign of something else: insects drawing it to your home. In this guide we explain whether geckos are actually harmful, why they come indoors, how to reduce them without poisons, how to deal with their droppings hygienically, and when the real solution lies in controlling the insects they feed on.

What is the house gecko and how do you recognise it?

The house gecko is a small lizard, usually around ten to twelve centimetres long including the tail, pale grey, pale pink or brown in colour, and its skin can look almost translucent. It has sticky pads under its toes that let it walk on walls, ceilings and glass, and large eyes without movable eyelids, as it is mostly active at night. You may sometimes hear it make a short chirping or clicking sound, especially in the evening.

It helps to tell it apart from other creatures you might see around the house:

Desert and garden lizards: live on the ground among sand, stones and plants, are active during the day in the sun, and rarely climb smooth walls or come into rooms.
Skinks: have smooth, shiny bodies and short limbs, and move quickly on the ground. They may come into yards in sandy areas but do not cling to ceilings.
House geckos: are the ones you see at night on walls near lights, behind frames, pictures and curtains, and in the corners of the ceiling.

The clearest sign of geckos, even if you have not seen one, is their droppings: small, dark, elongated pellets with a white tip, found on floors, window ledges and below the spots where they rest.

Are geckos harmful?

The short answer: house geckos are not venomous, do not attack people, and rarely bite unless held tightly, in which case the bite is small and superficial. In fact, they eat plenty of mosquitoes, flies, moths and small insects. Even so, there are understandable reasons why people want fewer of them indoors:

Hygiene: like many reptiles, their droppings can carry bacteria such as Salmonella, so they should not be left on kitchen surfaces or near food and children's things.
Stains and smells: droppings building up behind curtains, frames and on window ledges leave marks on paint and fabrics.
Falling into food: a gecko can occasionally drop from the ceiling onto uncovered plates or into pots.
Discomfort and fear: some family members, especially children, are afraid of them, and for many people that is reason enough to look for a solution.
A sign of a bigger problem: lots of geckos indoors usually means lots of insects, and that is the problem that deserves the most attention.

Why are there geckos in your home?

Geckos go where they find food, warmth and hiding places. In the UAE, most homes provide these in one way or another:

Lights and insects: outdoor lights and lit balconies draw mosquitoes, moths and flies at night, and geckos know this well, so they sit beside the light and wait. If windows are open or have no screens, insects follow the light inside and the geckos follow them.
Gaps around AC units and pipes: the spaces around split AC pipes, drain lines and cables are among the best-known ways in, especially in older apartments and villas.
Gardens and plants: in villas with gardens, and apartments with dense plants on the balcony, insects and hiding places sit right next to the house.
Doors and windows: a small gap under a balcony door, or a window that does not close properly, is enough for one to get through.
Clutter and storage: cartons and items piled behind furniture and in storerooms give them safe hiding places during the day.

They appear more in the warmer months, when insects are more active. If you want to understand when different pests are active through the year, see our UAE seasonal pest calendar.

How to reduce geckos without poisons

The most effective methods with geckos need no chemicals. They rely on reducing what attracts them and closing the way in. Follow these steps:

Change your outdoor lighting: use yellow or warm-toned bulbs around doors and balconies, as they attract many insects less, and switch off unnecessary lights or use motion sensors.
Move lights away from entrances: where possible, place the light source some distance from doors and windows so insects gather away from the way into the house.
Fit screens: fine, intact mesh on windows and balcony doors keeps out both insects and geckos. Check old screens and replace torn ones.
Seal the gaps: close the spaces around AC pipes and cables with a suitable sealant, and fit rubber strips under doors that open to the outside.
Reduce hiding places: move furniture slightly away from walls, lift stored cartons and items, and clean behind frames, pictures and curtains regularly.
Tidy the balcony and garden: trim plants that touch windows and walls, and do not leave standing water in plant saucers, as it attracts mosquitoes.

If you find a gecko in the room

The easiest and most humane approach is to let it out. Switch off the indoor lights and open the door or window to the outside, leaving a soft light on outside, and it will usually leave by itself. If it is somewhere low down, gently place a plastic container over it, slide a piece of card underneath and take it out to the garden or away from the house. Do not grab it by the tail, as it may shed the tail as a defence and escape.

What we do not recommend

Glue traps: they cause the animal long suffering, can catch small birds or pets, and do not solve the cause of the problem.
Poisons and insecticides sprayed on geckos: we do not recommend using poisons against geckos inside the home. They can harm children and pets, and a gecko may die somewhere hidden and cause a smell.
Mothballs: the substance is harmful to breathe and should not be placed in open living spaces, especially around children.
Eggshells, coffee and pepper: these remedies are widely shared, but there is nothing to show they reliably repel geckos, and they can attract other insects if left in corners.

Control the insects they feed on

This is the step that makes the biggest difference. A gecko that finds no food in your home will move elsewhere. Watch these insects in particular:

Mosquitoes, flies and moths: these are what draw geckos to lights the most. Get rid of standing water, keep bins closed and use screens. If the problem is large, our mosquito and fly control service in Dubai can help.
Cockroaches: especially in kitchens, bathrooms and drains. Small cockroaches in apartments need specialist treatment with gel baits; read about them in our guide to German cockroaches in Dubai apartments.
Ants and small insects: around food crumbs and sugar. Clean surfaces daily, store food in airtight containers, and see our guide to getting rid of ants in the kitchen.
Spiders: cobwebs in corners mean there are insects for them to feed on, so remove them regularly.

In homes near the desert, remember that the insects that attract geckos also attract scorpions, so reducing them helps you twice over. Read more in our guide to scorpions and snakes around desert homes.

Hygiene around gecko droppings

Dealing with droppings correctly protects your family and stops stains spreading. Follow this method:

Put on gloves before cleaning.
Do not sweep up dry droppings with an ordinary broom or brush them off, so they do not crumble and spread.
Spray the area with a suitable household cleaner or disinfectant and leave it for a minute so the droppings soften.
Wipe them up with a paper towel and put it in a sealed bag in the bin.
Clean the surface again with disinfectant, especially if it is in the kitchen, on the dining table or near children's things.
Wash your hands well with soap and water afterwards, even if you wore gloves.

Always cover food and plates, wash dishes that have been left uncovered overnight before using them, and clean pet food bowls daily. Teach children to wash their hands if they touch a gecko or its droppings. For more on disinfecting surfaces safely, see our home disinfection guide.

What does a pest control company do about geckos?

A serious pest control company will not promise to eliminate geckos with poisons; it works on the cause. During the visit, the technician inspects the home inside and out and identifies which insects are present and where, how the geckos are getting in, and the sources of light and moisture. They then treat the insects with the method that suits each type, such as gel baits for cockroaches in the kitchen, residual spraying in outdoor areas and drains, and treating mosquito breeding spots in the garden, and give you a list of gaps to seal and suggested lighting changes.

Before the visit, empty the lower kitchen cupboards if asked to, cover food and cooking utensils, and keep children and pets away from the rooms being treated. After treatment, follow the technician's instructions on when to go back into rooms and on ventilation, and do not wipe away sprayed areas or baits in the first few days.

Results appear gradually: as insects decline over the following weeks, there are fewer geckos indoors because they no longer find enough food. You may need a follow-up visit to complete control of cockroaches or mosquitoes, especially if the infestation is long-standing. Pest control usually starts from 150 dirhams for a small apartment and varies with the size of the home, the type of insects and how severe the infestation is.

When do you need a pest control company?

If geckos have become common inside the rooms and are no longer limited to the balcony or yard.
If you keep noticing cockroaches, ants or mosquitoes along with the geckos.
If you repeatedly find droppings in the kitchen or near food.
If the house is near a large garden or sandy area and you keep seeing insects and scorpions.
If you have tried sealing gaps and changing the lighting and things have not improved.

You can book our pest control service in Dubai to inspect your home and treat the insects that attract geckos.

Frequently asked questions

Are geckos venomous?

No, house geckos are not venomous and pose no direct danger to people. The main health concern is their droppings, which can carry bacteria, so hygiene around them matters.

Is there a spray or pesticide that kills geckos?

We do not recommend it. Pesticides are not a suitable solution for geckos inside the home and can harm your family and pets. The better solution is reducing insects, sealing gaps and changing the lighting.

Why do I always see geckos near the same light?

Because that light attracts insects every night, so it has become a regular hunting spot for the gecko. Try replacing it with a yellow bulb, running it for less time, or moving it away from the door.

Does having geckos mean my home is not clean?

Not necessarily. Geckos come into clean homes too if there is lighting that draws insects and there are gaps around AC units and windows. But lots of them inside the rooms is worth investigating for an indoor insect source.

Do geckos disappear straight after insect control?

It does not happen in a day. Their numbers drop gradually over weeks as insects decline, and the result lasts if you keep up the sealing, screens and lighting changes.

Do geckos bite children?

Very rarely, and usually only if a child tries to catch one. Teach children not to touch them, and to wash their hands if they touch a gecko or its droppings.
