Their stings are venomous and can give severe allergic reactions to many people.
But at times, during certain months, you’ll find lazy wasps in your house.
You’ll find lethargic wasps lying around on the floor, in the basement, on windowsills, and in your yard or garden.
You wonder where they come from and what does it signifies.
In this post, you’ll get to know both.
So, let’s jump right in.
Time Of The Year When You’ll See Lethargic Wasps In House
You won’t see half-dead wasps all around the year.
Sightings of lethargic wasps in the house begin from the fall months and continue till the end of winter.
So, from late August, you’ll see lethargic wasps lying around in your home.
But why do you see these half-dead wasps, particularly during this time of the year?
Why You See Lethargic Wasps In Your House?
The sightings of lethargic wasps are deeply related to the wasps’ lifecycle.
But one thing is for sure when you see half-dead and drunken-like wasps in your home.
It’s that there’s a wasp nest in your home or your vicinity.
In certain cases, especially in the fall and winter months, you’ll see wasp swarms outside your house despite no nests around.
Let’s take a step back to understand why you see these lethargic wasps.
After hibernating during winters, the female wasp searches for a location to build her nest.
She looks for places like a mammal burrow, wall voids, tree branches, and many other places where paper wasps, hornets, and yellow jackets build their nests.
The female wasp starts to build the nest from the spring months after she finalizes the nesting place.
Once she starts, many male wasps join her.
Once the female wasp starts building her nest, many male wasps join her.
The purpose of the male wasps is to help the queen build the nest and to impregnate her.
The female wasps lay her eggs in the nest. The male wasps’ job is to protect the nest and rear the larvae in the nest.
The entire activity of building the nest, laying eggs, and rearing the young continues till the end of 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.
If there’s a wasp nest nearby your home, then you see these dying wasps in different places in your home.
But the female wasps don’t die during the winter months. The female wasps from the nests go on for hibernation during the winter months.
The female wasps look for warm places in and around your home during the winter months.
So, places like a chimney, basement, garage are suitable places for the female wasps to hibernate.
Once the winters are over, the female wasp moves out from hibernating and start looking for a place to build the nest.
What You Should Do If You See Lethargic Wasps In House?

Winter is the safest time to remove wasp nests. The number of wasps inside the nest is less because most of them have exited the nests.
How Long Does It Take For A Wasp To Die In A House?
The answer to this question is it depends.
It’s because if there’s a wasp nest inside your home, then the wasp can finish its entire lifecycle before it dies.
