Time of the year when you’ll see lethargic wasps in the house

Wasps do not remain half-dead all year round. We saw sluggish wasps within the house starting in the fall and continuing through the winter. So starting in late August, you’ll start to notice sluggish wasps sitting around your home.

However, why do you see these half-dead wasps, particularly at this time of year?

Why do You see Lethargic Wasps In Your House?

Lethargic wasp sightings are intimately related to the beginning phases of a wasp’s life cycle. When you observe half-dead and inebriated wasps inside your home, one thing is certain.

There is a wasp nest in or close to your home. When there are no nests nearby, you could witness wasp swarms outside your house, especially in the fall and winter. To understand why these wasps are doing so sluggishly, you must step back.

The female wasp hibernates and looks for a good nesting location in the winter. She looks for paper wasp, yellow jacket, and hornet nests in mammal burrows, wall voids, tree branches, and other locations.

After choosing the nesting location, the female wasp starts construction on the nest in the spring. Once she starts, she draws a lot of male wasps. Many male wasps accompany the mother wasp as she starts to construct her nest.

The nest is constructed by the male wasps, who also fertilise the queen. In the nest, the wasp’s female deposits her eggs. The male wasp’s responsibilities include guarding the nest and raising the larvae. The entire nest-building, egg-laying, and child-rearing process continues in the fall.

It’s during the end of the fall and beginning of winter the death season for wasps starts. The male wasps start to die during the winter months. It’s common to see dead wasps in different parts of your home if there’s a wasp nest nearby.

The female wasps do not, however, perish throughout the winter. Female wasps from the nests hibernate throughout the winter. Female wasps seek out warm locations in and around your home during the winter. As a result, garages, basements, and chimneys are ideal locations for female wasps to hibernate.

Female wasps emerge from hibernation once the winter is over and look for a place to build nests.

When a wasp dies inside a house, how long does it take?

The answer to this question is, “It depends.” What is the cause? This is due to the fact that a wasp can live out its whole life cycle within your home if a wasp nest is there.

In other words, it can remain alive for six to eight months within your house. During the winter, a male wasp becomes drowsy and can be found on the floor or in other areas of your home.

In contrast, a wasp that unintentionally enters your home and is unable to leave will expire after 3–4 days if it is not provided with food or water.
