As a homeowner, it’s not uncommon to come across a wasp or two in your backyard during the warmer months. However, when you start seeing wasps inside your home, it can be concerning, especially if you don’t have any open windows. In this article, we’ll discuss the different types of wasps that may find their way into your house and what you can do to keep them out.

DIY Wasp removal recommendations

For non aggressive wasps I've had great luck spraying the nests with this Spectracide wasp remover in the evening. For more aggressive wasps I also use this rediculous looking upper torso Beekeeping suit. It seems silly, but trust me, it's amazing.

The Types of Wasps That Can Enter Your Home

Paper Wasps

Paper wasps are one of the most common types of wasps found in North America. They build their nests in sheltered areas, such as under eaves, decks, or in attics. If you see paper wasps flying in and out of your home, there’s a good chance they’ve built a nest somewhere nearby.

Yellow Jackets

Yellow jackets are another type of wasp that can enter your home. They are attracted to sweet foods and can often be found hovering around garbage cans or outdoor eating areas. If you have a yellow jacket nest near your home, you may see them flying in and out of small openings, such as cracks in the foundation or gaps in siding.

Mud Daubers

Mud daubers are solitary wasps that build their nests out of mud. They are typically not aggressive and do not pose a threat to humans. However, if you see mud daubers flying in and out of your home, they may have built a nest inside.

How to Prevent Wasps From Entering Your Home

Remove Food Sources

Wasps are attracted to sweet foods and other sources of protein. To prevent them from entering your home, make sure to clean up any spills or crumbs immediately. Keep all food stored in sealed containers and dispose of garbage regularly.

Seal Gaps and Cracks

Inspect your home for any gaps or cracks in the foundation, walls, or siding. Seal these openings with caulk or another appropriate sealant.

Install Screens

If you don’t have screens on your windows, consider installing them. This will allow you to keep your windows open without worrying about wasps or other insects entering your home.

Keep Outdoor Spaces Clean

Regularly clean outdoor eating areas, including patios and decks. Wasps are attracted to sweet foods, so make sure to clean up any spills or messes right away.


Seeing wasps inside your home can be alarming, but there are steps you can take to prevent them from entering in the first place. By removing food sources, sealing gaps and cracks, and installing screens, you can help keep these stinging insects outside where they belong. If you have a wasp infestation that you can’t handle on your own, contact a professional pest control service to safely remove the nest.
