Can Bees Get in Through AC unit?

It’s the middle of summer and you’re trying to cool off in your air conditioning unit, but there are bees everywhere! 

In short, yes, bees can get inside AC units and other appliances. While bees can get in or around your AC unit, there are ways to get rid of them that won’t involve calling an exterminator who will charge you a fortune for doing nothing more than spraying some pesticides around. 

In this article, we’ll explore several simple things you can do yourself at home if these bees have decided to make your AC unit their new home permanently.

How bees get in through AC units

It’s important to be aware of how bees get in through AC units, because if you notice bees in your home, the first thing you’ll likely do is turn on the air conditioning. If bees have gotten inside your AC unit and are trying to escape from it, turning on the air will only make things worse for them—and for you.

The truth is that there are many ways for bees to get into an AC unit: they can crawl through the vents or drain pipe from outside; they could find their way up through a hole in the bottom; or if there isn’t any debris blocking them (like leaves or dirt), they could find their way inside through your condenser unit when it was running last time you used it.

If you notice bees in your home, the first thing you’ll likely do is turn on the air conditioning. If bees have gotten inside your AC unit and are trying to escape from it, turning on the air will only make things worse for them—and for you. Once you have done this, it’s crucial to know what to do after discovering that you have a couple of bees inside your AC unit.

What can I do to stop bees from getting into my AC unit?

The first step you can take is to make sure the AC unit is clean and clear of debris. If there are any stray leaves or other items that could potentially block the vents, remove them immediately.

Make sure the AC don’t have any shrubs, trees or buildings blocking it from working properly; this can cause overheating in your system which will cause damage down the line and cost you more money than necessary on repairs.

Next, check to make sure that the air filter is clean. If it’s clogged with debris, this can also cause overheating and damage your unit down the line. Finally, check for any leaks in your system by spraying soapy water on all of the lines leading into and out of the AC unit itself.

What should I do if I have bees in or around my AC unit?

If you’re dealing with bees in your AC unit, it’s important to act quickly. Here are some steps you can take right now:

  • Do your research: Sometimes pests like bees can be removed without hiring an expert; search for bee blogs on the Internet for tips on how to do this safely.
  • Hire a beekeeper: Contact a beekeeper if there is no option available through these other resources—they will know how best to remove them from your AC unit without harming the bees or yourself!

Where are other common appliances for bees to nest?

Other appliances that are prime nesting areas for bees include refrigerators, freezers, stoves, microwaves, ovens and dishwashers. 

If you find a nest in any of these areas it is most likely that others may be nearby as well. A good sign to look for is if there are honeycomb cells or bee larvae present. If you do discover an infestation in your kitchen this can be troubling since bees often fly into the home through open windows or doors while they gather pollen and nectar from nearby flowers or plants. 

You may also see new hives appear on your property when the weather changes to warmer temperatures outside which will draw out more insects looking for food sources!

It’s important that homeowners pay attention when they notice a problem with their AC unit because it could lead them down a rabbit hole of discoveries about other pests living inside their homes too!

Are there any bee-proof AC units?

Unfortunately, there are no AC units that are completely bee-proof. However, you can use a bee-proof cover over your unit to prevent bees from entering into it. This is particularly effective if you live in an area where the weather is dry and it doesn’t rain much.

You should also check to see if anyone has reported any bee-related issues with your AC unit before installing one of these covers on top of it; some people have reported problems with them blocking airflow or letting dust collect inside the unit itself. 

What kind of bees get in through AC units?

Bees get in through your AC unit for a variety of reasons. Some species are attracted to the water that builds up inside your AC unit when it’s turned on, so they can drink from it. Others use the vents and openings as an easy way to access your home. 

The most common bees that get into AC units are:

  • Baldfaced hornet (or white-faced hornet)
  • Yellow jacket (or vespid)
  • Honey bee (Apis mellifera)   
  • Bumble bee
  • Yellow hornet (Vespa simillima) and others like paper wasps and red wasps
  • carpenter bees
  • leafcutter bees
  • mason bees
  • blue orchard bees

Bees can also be motivated by other things they find in the air conditioning system that they like—such as pollen or nectar—or by the vibration of running fans.


So, can bees get in through your AC unit? Yes, they can. This can be a problem if you have allergies or are otherwise allergic to bee stings. You might also want to consider closing off vents during the summer months as well so that this does not happen again in future years.
