It’s pretty common to spot a gecko darting across your wall or ceiling—and most of us instinctively try to shoo it away. But what if we’ve been getting it all wrong? These little lizards aren’t pesky intruders—they’re actually some of the best allies you can have in your home.

Why do geckos get such a bad rap?

Maybe it’s their odd look or the way they move so quickly that catches people off guard. But the truth is, geckos are totally harmless to humans. In fact, they play a vital role in keeping your home pest-free: they’re excellent insect hunters.

A surprisingly helpful diet

Geckos snack on a wide range of bugs that can otherwise overrun your living space:

• Cockroaches: These tough-to-kill pests are top of the menu for geckos.
• Mites and flies: Geckos help control their numbers, especially in spots where they multiply fast.
• Spiders, termites, and wasps: Not only are these pests annoying, but they can bite or cause damage—and yes, geckos go after them too.

By eating these insects, geckos act as a natural line of defense against full-blown infestations.

Living peacefully with geckos has its perks

Having a couple of geckos around can seriously cut down your need for insect sprays and other chemicals. And unlike many bugs, geckos won’t leave toxic residues behind—they’re safe for your home and your health.

Want their help without letting them take over?

Here’s how to keep that balance:

• Don’t rush to chase them off: They usually don’t hang around in one spot too long.
• Tone down outdoor lighting: Bright lights bring in bugs—and where the bugs go, geckos follow. Reducing unnecessary lights can help if you’re not a fan of frequent gecko visits.
• Keep things tidy: A clean home limits insect activity, which in turn reduces gecko interest.

Time to rethink things

Rather than seeing geckos as creepy or bothersome, try viewing them as quiet little protectors working behind the scenes. Next time you see one, skip the chase—and give a nod to your home’s tiny, natural pest controller.
