Can Roaches Come in Through Air Vents?

It’s safe to say that cockroaches are one of the most hated insects on the planet. Even though they aren’t poisonous and don’t pose a threat in most cases, many people have a true fear of cockroaches. The official name for the phobia is katsaridaphobia.

We know that roaches can squeeze through cracks and crevices that seem paper-thin, and they’re always crawling across pipes on their quest for water. However, there may be another route inside that’s much more accessible. There’s a chance that cockroaches are making their way inside through air vents.

Keep reading to find out if your vents are giving roaches direct access into your home.

Air Flow is No Match for Roach Legs

If you thought that blasting air through you vents would keep roaches from crawling through, think again. Roaches are made to make their way through many odd spaces thanks to their amazing legs.

Roaches are renowned climbers. They have six legs and each one has two claws that latch on tight to virtually any surface. There are also tiny hairs all over the legs that increase a roach’s ability to grip. Their “knees” also sense the tiniest vibration that serves as an early warning sensor for the air kicking on.

Long strong short – even if the air is flowing, roaches can make their way through the ducts and out the vents.

Vents – The Perfect Roadway for Roaches

When you think about it, vents are perfect for roaches, especially when the heaters get turned on. Air ducts are an entry point into the home, and the roaches work their way through the entire house. Roaches are always looking for a way inside, and this is an obvious access point.

Another thing that attracts roaches is the fact that vents are dark areas. Cockroaches are nocturnal insects that like to stay in the shadows. Vents give roaches a route around the house that’s free of light.

The other thing that makes vents a perfect environment for roaches is the heat and moisture. Roaches prefer places that are warm and moist, which is why they are so prominent in the south. During the fall and winter when the heat is on, the air vents are one of the most comfortable spots in the house for roaches.

Why Roaches in Vents is Such a Big Problem

The biggest problem is that it can be tough to treat roaches that have gotten into vents. Air ducts are a part of a home’s inner workings. Few pest control companies are actually going to get into the airways, and it’s nearly impossible for homeowners to do this on their own. Often you’ll need a very thorough pest treatment in order to eradicate roaches that have found their way into the ventilation.
