Vents can also let in gnats.

Although most gnats won’t live in your vents, as they don’t like dry conditions or the wind stream, they can still use vents as a way to enter your home.

Dryer vents and kitchen vents are particularly prevalent courses for gnats looking for an excellent indoor location.

Gnats can get in through these dryer vents into the room where the dryer is located and proceed to other spaces of the home.

They can also get in through kitchen vents, which poses an especially critical wellbeing and security concern.

To avoid gnats from entering through vents, get vent covers to prevent gnats from utilizing them as a travel course into your home.

Gnats not only get into homes through entry points; sometimes, they breed inside homes.

It is worth noting that gnats can lay over 100 eggs at a time! These eggs can hatch into larvae within 3 days.

Considering these numbers, you could have a sudden appearance of gnats easily! All it takes is one pregnant gnat to enter your home.


Fruit attracts gnats!

Gnats can lay their eggs inside the fruit, be wary of any fruit that has been left untouched for too long, as this is an ideal place for eggs to be laid.

Keep an eye out for the larvae.

Most pests that come into your home will be looking for a water source. These include leaks, collections of water, a nearby pond or lake, or even a hot tub.

Gnats will lay eggs around these areas, so fix any leaks. If you live near a lake or pond, sure up your defenses!


Fungus gnats like to lay eggs in damp potting soil. It offers a water source to the larvae once they hatch, but it also gives easy access to food in the form of plants, vegetables, or fruits being grown nearby.

It’s challenging to protect against, but it is worth treating potted plants to ensure gnats cannot lay eggs in the soil.
