Thanks to their flat, small bodies, cockroaches are experts at squeezing through small spaces undetected, and your home's air vents are one of the places you'll most often find them. Household vents make perfect pathways for cockroaches, especially in cold months when they search for warmth in hidden spaces.

When this happens, most people turn to pesticides or insecticides. However, if you fail to address the source of entry, the bugs problem is more likely to reoccur. Note that you should never attempt spraying pesticides into the AC vents.

But when it comes to getting rid of cockroaches from your HVAC system, you do have several options.

1. Call in an HVAC Professional:
2. Plug Any Holes or Cracks:
3. Fix Leaks Around Your Air Conditioner.
4. Keep Your House Cool.
5. Clean Regularly.
6. Perform Regular Gutter Maintenance.

You can manually remove any debris or buildup or use cleaning solutions to clean your AC vents. This should go a long way towards deterring bugs from entering or exiting your HVAC system ducts. Another key factor that works to get rid of bugs in vents is to have your AC unit installed by a professional.

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.

With a physically small flat body, there is more than enough room for these cockroaches to squeeze their way in through loose seals around windows and doors, or tears along window or door screens. Remember to seal your windows and doors.

Dust mites live in warm, humid places. Dust mites do not live in air ducts in homes. Duct cleaning will not reduce numbers of dust mites. Filters on the heating/cooling systems or the vents will not control dust mites though will help reduce dust in the home.

What's Crawling Around in Your Home's Air Ducts?

• Bugs and Insects. There are few things worse than working to kill a spider and watching is escape into the air vent.
• Rodents.
• Birds.
• Mice in Air Ducts.

Some strong scents, such as lavender and mint, have been known to repel cockroaches. Therefore, growing these plants or misting their scent with essential oils can keep them away.

Eliminate Food and Water Sources. To keep roaches away at night, it's crucial to eliminate their food and water sources. These pests are attracted to any accessible food, so avoid leaving food and drinks uncovered or near your bed.

Invest in Duct Cleaning For best results, schedule a routine duct cleaning every year. Eliminating dust mites takes time, but performing these tasks is well worth it to enjoy improved indoor air quality and fewer symptoms. Don't let your family suffer another season.

And when mice get in your home, it's not uncommon for them to build nests in your ductwork and ventilation systems, giving them access to food and other necessities throughout your house.
