Two ways wasps in Colorado will nest under your deck

Some wasps create aerial nests out of paper. They look like big, gray paper eggs. Some wasps create nests you won't see. They make their paper nests inside ground holes created by rodents. It is important to understand what wasps make their nests from and that certain wasps create their nests in the ground—particularly if you're hoping to deter them. We'll get to prevention tips in a moment. First, let's look at why those stinging pests want to create a nest down there.


Reasons wasps make nests underneath your deck

Wasps that create aerial nests will do so in protected areas. They want to shield their nests from strong winds and rain. Often, they create nests on roof overhangs or on the ceilings of porches. But they can also create nests underneath decks.

Wasps that build nests in the ground will do so if they find ground holes created by other animals. Most of these wasps don't dig their own holes. They live off the generosity of critters. Once inside a ground hole, they'll do some excavation to make the hole their home. 

Along with ideal conditions for building a nest, there is another important reason wasps will choose to build a nest under your deck: Food. These insects want to create their nests close to food sources. They feed on the nectar in flowers, so establishing a nest near flower beds is ideal. They also feed on protein sources found in trash receptacles. If you sit your receptacles next to your back deck, the scent might attract wasps.

What can you do to deter wasps?

As we pointed out, certain wasps will choose to build under your deck because it provides protection. Dragging wood and other materials out from underneath your deck or blowing leaves out of that space can make the void under your deck feel open and less protected. When nesting locations are near the ground, wasps aren't as prone to build a nest unless there is clutter on the ground to provide some protection from animals.

If you're looking to deter wasps that build nests in the ground, there is one simple step you can take. Look for the holes and fill them in. You may also deter rodents and other wildlife on your property to prevent them from digging holes in the first place. Do this by addressing the food sources that attract them, like seeds, nuts, fruits, and exposed trash. Speaking of trash, a simple way to deter wasps from creating a nest under your deck or on your roofline is to move trash receptacles away from your exterior. 

Another food to consider is the nectar of flowers. While it isn't practical to remove all of the flowers from your property, you may remove flowering weeds from your lawn and landscaping to reduce sources of nectar. That will help deter wasps.

One last factor to consider is nesting materials. Wasps gather pulp from decaying wood to make the paper material they use for building their nests. Remove logs and stumps, protect campfire wood, and store dead branches in a covered bin.
