Harmless in itself, and a sign of something else — a house with lizards is a house with enough insects to feed them.
Geckos follow their food, which is why they gather around outdoor lights, windows and anywhere flying insects collect after dark. They enter through gaps around AC lines, drains and door seals, and shelter in wall cavities and behind fixtures during the day.
Lizards don't bite or carry disease in any meaningful way, but their droppings stain and soil surfaces, and in a kitchen or food premises that is a hygiene failure regardless of the animal being harmless. For many households it is simply unwanted.
The effective approach is to remove the food supply and the way in, not to chase the lizard: we treat the insects it feeds on, proof gaps around pipework, vents and door seals, and advise on outdoor lighting that attracts fewer insects in the first place.
Practical steps that make a repeat infestation far less likely after treatment.
Deal with the insects first — remove the food and the geckos leave on their own
Switch outdoor lights to warm tones, or move them away from doors and windows
Seal gaps around AC pipework, drains and door seals
Fit screens to windows and keep external doors shut after dark
The things people ask us most before booking this treatment.
No — they don't bite or carry disease in any meaningful way, and they eat insects. The real objection is their droppings, which stain and soil surfaces. In a kitchen or food premises that's a hygiene failure regardless of the animal being harmless.
Remove what they're eating and the way in. Treat the insects, seal gaps around AC pipework, drains and door seals, and change outdoor lighting to warmer tones that draw fewer insects. Chasing the gecko itself achieves nothing.
Generally yes — they settle where there's enough food to be worth staying for. A sudden increase indoors is usually worth treating as a signal about the insects rather than about the geckos.
