Can A Wasp Nest Damage Your House? 

If we’re cutting straight to the chase here then yes, it is possible that a wasp nest can cause damage to your house. In what capacity will depend on several factors including the positioning of the nest and the conditions in which the nest is located.

The weight of the nest is also a consideration. Wasps will likely get to work in a lesser-used area of your home, meaning you might not spot it until it’s a considerable size. The bigger the nest, the heavier it’s likely to be, and heavy nests can cause strain to structural areas depending on location.

In general, wasp nests don’t often do much damage to a house compared to indoor pests like rats and mice but large nests still present a risk.

This risk increases even further if the nest somehow becomes damp and is attached to a porous material such as wood. The dampness from the nest can seep into the wood, potentially causing rot and structural damage to your home.

Technically, if the nest isn’t bothering you and you’re sure it’s doing no damage to your home then no, a wasp nest doesn’t need to be removed. However, if there are any safety issues such as allergies, then likely the safest thing to do would be to have the wasp nest removed.

The simple answer is np, wasps don’t return to old nests. This means that if you leave the nest as it is, eventually the wasps will die out. Wasps may return the following year and build a new nest, however, if it presents a good nesting location for the new queen.
