How to Prevent Bugs in Your Air Ducts!

February 24, 2022

This one is sure to get your attention! Bugs could be getting into your home through ducts and vents. Read on to learn how to prevent this!

Common Problem

If you have a bug problem in your home, there’s a surprisingly big chance that ducts and vents are the culprit. Yes, the other big way that creepy crawlies get into your home is through an unsealed front door, or through cracks in your walls/foundation, but bugs can also get in through your air ducts and vents. And yes, we’re talking about more than just ants here – we’re talking roaches and other big household pests.

Vents, Vents, Vents

Of course, your next question probably is, how the heck would bugs get in this way, if your vents are properly covered and sealed?

Well … are you quite sure your vents are covered and sealed? As you might already know, there are several vent openings outside your home.

Walking around the perimeter, you’ll see intake vents. These vents allow fresh air into your home, and they are taking in air regardless of whether you’re currently running your AC or furnace.

You’ll also see exhaust vents. There are many different exhaust vents: your bathroom fan, the range hood in your kitchen, and your dryer all have exhaust vents to let this air leave your home. Another kind of exhaust vent is the one that lets CO2 produced by your furnace out, so that the CO2 doesn’t get into your home.

Cover Your Vents

So the problem here is, of course, an uncovered vent. If you walk around outside your house and see that a vent is not properly covered by a screen (maybe the screen has fallen off, or even been chewed on by pests!), that’s exactly how bugs get in.

In some cases, even bigger pests can get in: would you rather be living with bugs or with a giant rat? Hopefully, you never have to answer that question!

Vent screens are also useful for keeping dirt and other debris out of your home’s air ducts.

Simple, Inexpensive Fix

Luckily, fixing this problem is simple. You just need to visit your local hardware store in Phoenix or Tucson, and pick up a piece of screen/mesh that fits into the hole. Voila, problem solved!
