Small house geckos are normal in Thailand and usually enter because insects are available. Their droppings are typically small, dark pellets with a distinct white chalky tip. That appearance is different from ordinary rat or mouse droppings, although uncertain or extensive pest evidence should still be inspected professionally.
What gecko droppings usually look like
Reptiles pass a dark fecal portion and a white urate portion together. In a Thai home, a small dark pellet with a clearly attached white end is therefore commonly from a house gecko rather than a rodent.
Rodent droppings generally do not have that white urate cap. Size, quantity and location still matter, so do not identify an infestation from one ambiguous mark alone.
Why geckos come inside
Geckos follow food. Exterior lights, open windows, gaps around air-conditioning lines and insect activity can make a room attractive.
- Repair insect screens and seal gaps around pipes, doors and window frames.
- Reduce insects with clean food storage, covered bins and prompt removal of standing water.
- Move bright exterior lights away from doors or use less insect-attracting fixtures where practical.
- Clean droppings with gloves and disinfect the surface; avoid dry sweeping contaminated dust.
When to call pest control
Call a licensed pest professional when droppings are numerous, lack the typical white tip, appear with gnaw marks or food damage, or continue after entry points are sealed.
Large tokay geckos can bite when handled. Do not grab or trap one by hand; give it an exit route or use a humane wildlife-removal service.
Questions and answers
Are geckos dangerous in a home?
Common house geckos generally avoid people and help consume insects. Keep surfaces clean and avoid handling them.
How can I tell gecko droppings from rat droppings?
Gecko droppings commonly have a dark pellet and an attached white urate tip. Rodent droppings usually lack the white cap and may appear with gnawing or food damage.
Should a landlord remove every gecko?
Complete exclusion is difficult in tropical buildings. The useful request is to repair screens and entry gaps and address any insect or sanitation problem attracting them.
