With all of the beauty surrounding us, it’s hard to imagine that danger lurks beneath autumn’s surface. But it does and if you are reading this post, chances are you already have an idea why. It’s the precise time of year when one pest becomes extremely aggressive, leading many to ask, “Why are yellow jackets going behind the siding of my house?” We hope to answer that pressing question for you today as well as offer tips on making it through the season unscathed.

Why Do Yellow Jackets Love Cavities?

Considered members of the wasp family, some species inherently look for protected cavities where they can build massive nests virtually undisturbed. Unfortunately for Michiganites, that includes our homes’ siding. Most types of siding feature small openings. They’re the perfect size for wasps and are often too small or concealed for many of the insects’ natural predators to find useful during attacks.

In addition, the cavities underneath of the siding may offer protection from more than just yellow jackets’ natural predators. For example, the covering will undoubtedly shield them from the intense sunlight, hard rain and blustery winds. Also, it likely traps in heat, which the yellow jackets need to remain active and carry out their daily activities. With that in mind, it’s highly likely that a lone yellow jacket found its way underneath of your home’s siding during the spring.

Spring Brings On the Need to Build

That’s when they tend to start building their nests for mating season. Once underneath of the siding, it probably used the home’s weathered wood, tar paper and other organic building materials to further its nesting efforts. Wasps are known to take those types of natural elements and combine them with their saliva to create a protective, paper-like material. The paper-like material is then used to create borders and layers within the nest.

A Room by Any Other Name

Why do yellow jackets make borders and layers underneath of a home’s siding? Simply put, it’s for the very same reasons we section off areas of our homes. Each section of the wasp’s nest has a function. For example, one area may serve as a food cache and another may be used as a nursery for its young. Understandably, yellow jackets are just as protective of their homes and families as we are. However, they are more so in the fall because it traditionally marks the end of the adults’ life cycles.

Ensuring Future Generations Survive

Because the adults’ lives are winding down, they’ll work even harder to ensure that their offspring will be well taken care of in their absence. Accordingly, they become more active and aggressive around the nest. Most of their activity centers on preparing safe areas for the young to overwinter and stocking up on food. As such, you’ve probably seen them coming and going from their home underneath of the siding more often these last few weeks.

Chief Reason to Defend and Prepare an Offensive

While the activity will die down once the frigid temperatures of winter set it, it is no reason to ignore the yellow jackets. If not taken care of now, the young will surely return in the spring and the cycle will start all over again. Therefore, it’s best to exterminate the colony and have the nest professionally removed before then. Afterward, you can call in the siding experts and have them seal up any holes that may attract other colonies in the future.
