If you've noticed more wasps trying to get into your home than usual over the last few weeks, you're not imagining things.
Whether they are bumping into your windows, or sneaking their way through balcony doors, wasps tend to try to get into our houses in the winter months.
If you aren't the biggest fan of wasps, you might find this very annoying – but there is a good reason for them doing it.
So why do they enter your home in the autumn and winter – and when do they die out? Here is everything you need to know.
When do wasps die?
During the spring and summer months, the male wasps, known as workers, have spent their days feeding on nectar and looking after the queen.
They source food, which can also be other insects or fallen fruit, and bring it back to the nest.
Wasps will eat just enough for them to sustain themselves, but anything left over will go to the queen so she can lay healthy eggs.
But during the winter, the queen going into hibernation due to the cold.
During the winter there isn't enough food, so she tries to sustain her energy levels.
This means the worker wasps can't feed off her larvae, and don't have a job to do – leaving them to fend for themselves.
Due to the lack of food in the winter, male wasps tend to die off, with a new generation of wasps taking over in the spring.
The majority of these die due to starvation, or are eaten by other insects or spiders.
Why are wasps trying to get inside your home?
When the weather becomes colder and harsher, the wasps flee in search of somewhere warm and dry.
In addition, because plants and flowers are dying off outside, the sweet scent of human food seems to draw them inside.
Your home may also find itself as a shelter for the queen, who is looking for somewhere to hibernate.
When temperatures dip below 10C, the remaining wasps become increasingly disoriented, according to PestBrisol.
The wintry conditions cause the wasps' central nervous system to shut down – similar to the of hypothermia in humans.
Are they more aggressive during the autumn?
It's also worth remembering that the hunger can make the wasps bolder and aggressive as they search for a meal.
They often go for the easiest option – which could be. Fizzy drink, discarded apple core, or a pint of beer from a garden.
Fermenting fruit can make the worker wasps become clumsy and brazen.
