Harmless and useful. The only cost is the small droppings on the windowsill.

Turn on a light at night and within minutes there is a small pale lizard on the wall beside it, waiting. Then a sharp chirp from behind the curtain, and another answering from the kitchen.

Where you’ll see it

Every house, every wall, every night. They gather around lights where the insects are and hide in gaps behind frames and furniture by day.

What to know

The house gecko arrived in the Americas from Asia and has made itself at home everywhere warm. It is harmless, cannot bite in any meaningful way, and eats mosquitoes, moths and cockroaches all night. The chirping is territorial. The droppings, small and dark with a white tip, are the only nuisance. A house with geckos is a house with fewer bugs, and most residents come to feel affection for theirs.

Questions people ask about this one

What is making the chirping noise in my house at night?

Geckos. The common house gecko calls with a series of sharp chirps or clicks, usually from a wall or ceiling near a light. It is announcing territory. It is also eating the insects the light attracts, which is why you want it there.

Wondering what else is out there?

Ask me on the call. I'll tell you what actually shows up in a Coco garden, what to do about it, and the one guy everyone rings when there's a boa in the roof.
