Lizard Control in Dubai — House Geckos in Apartments

Which lizards you're dealing with

Almost all house lizards in Dubai apartments are common house geckos — specifically Hemidactylus flaviviridis (the yellow-bellied house gecko) or Hemidactylus frenatus (the common tropical house gecko). They're 7–15cm long, pale cream to grey, and fully nocturnal. You'll see them on walls near light sources at night, hunting flying insects.

They're not venomous, don't bite unless cornered, and pose no direct health risk. The hygiene concern is their droppings — elongated black pellets with a white uric acid tip — which accumulate on walls, shelves, and any surface they regularly patrol.

Dubai also has outdoor monitor lizards (dhubs) and desert geckos, but these very rarely enter buildings and are a completely different issue.

Why your lizard population increases

Geckos are predators and their density in your apartment directly reflects the insect population available to them. The most common triggers for a sudden increase:

• New insect problem in the building — a nearby apartment with cockroaches, or a fruit fly outbreak in the waste room, creates an insect surplus the geckos exploit
• External lights near windows — balcony lights and outdoor corridor lights attract flying insects at night; geckos follow and find entry gaps near the window frames
• Warm months (April–October) — insect activity peaks in Dubai's summer, so lizard activity peaks alongside it
• New building or renovation nearby — construction disturbs ground-level populations and pushes them into adjacent buildings

How geckos enter apartments

House geckos can pass through gaps as small as 5mm. In Dubai apartments, the main entry points are:

• Gaps around AC pipe penetrations through exterior walls (these are rarely fully sealed)
• Window frame edge gaps — especially sliding windows where the rubber seal has degraded
• Under and around front doors if the door seal strip is missing or compressed
• Service ducts and electrical conduit entry points into the apartment
• Gaps around kitchen and bathroom pipes where they pass through walls

Geckos don't chew through materials — they only use existing gaps. This means exclusion is theoretically possible but requires systematic inspection of every penetration point.

What you can do yourself

1. Remove the food supply

This is the highest-leverage step. If you treat for flying insects and cockroaches effectively, gecko populations will decline on their own within 4–8 weeks because their food source disappears. Ensure bins are covered, food is stored in sealed containers, and kitchen cleaning is thorough.

2. Reduce outdoor lighting

If you have control over balcony or window-adjacent lighting, switch to yellow-spectrum LED bulbs — they attract significantly fewer flying insects than white or blue-spectrum light. This reduces the nightly insect supply near your entry points.

3. Seal key entry points

AC pipe penetrations are the most cost-effective sealing priority — buy expanding foam filler from ACE Hardware or a local hardware shop and fill the gaps around AC pipes on the external wall. Apply silicone sealant around window frame edges where gaps are visible. Add door seal strips to exterior doors.

4. Repellent options

Naphthalene balls placed near known entry points and in cupboards where lizards are active have a mild deterrent effect. Commercially available lizard repellent sprays (pepper-extract based) can be applied around entry points and window frames. These are short-term measures — they need reapplication every few weeks and work best combined with exclusion.

Professional lizard control

A professional lizard control service addresses the problem from both angles — food supply and physical presence:

Insect baseline treatment

We treat the apartment for flying insects (mosquitoes, moths, gnats) and crawling insects (cockroaches, ants) that make up the gecko's food supply. Residual insecticide on surfaces and gel baits in harborage points. This is included in a lizard control treatment as the root cause step.

Exclusion inspection

Technician inspects all AC penetrations, window frames, and door seals. We seal gaps where accessible and advise on the ones that require a maintenance engineer (shared building services ducts, for example).

Repellent treatment

Residual repellent gel applied at entry points, known patrol routes (wall-ceiling junctions near lights), and inside cupboards and storage areas where droppings are found.

Sticky traps

Placed near confirmed entry points for 2 weeks post-treatment to physically capture lizards that are already inside and haven't yet been deterred by the repellent.

Long-term prevention

• Annual insect treatment — the most effective lizard prevention is keeping insect levels low year-round
• Check window seals annually — rubber compression seals degrade in Dubai's UV and heat; replace them when you see gaps
• Don't leave balcony doors open at night near lights — this is the single highest-risk behaviour for gecko entry
• Report insect problems in communal areas — rubbish rooms, car parks, and stairwells with high insect activity feed the whole building's lizard population
