Spring marks the beginning of the wasp season in the UK, and April is when activity starts to increase. At this time of year, most of the wasps people notice are queen wasps emerging from hibernation and beginning to build new nests. Understanding what wasps do in early spring can help property owners identify nests early and arrange wasp control before colonies grow larger later in the year.
Why Wasps Appear in April
During winter, almost all wasps die off. Only fertilised queens survive by hibernating in sheltered places such as:
- Roof voids and loft spaces
- Wall cavities
- Sheds and garages
- Under tree bark
When temperatures begin to rise in spring, these queens wake up and start searching for a suitable place to build a nest.
Two of the most common UK species that appear in spring are the Common wasp and the German wasp.
The Queen Wasp Builds the First Nest Alone
At the beginning of the season, the queen is responsible for everything involved in starting the colony. She will:
- Locate a safe nesting area
- Chew wood fibres to create a paper-like nest material
- Build the first few hexagonal cells
- Lay eggs inside the cells
- Hunt insects to feed developing larvae
This stage typically lasts around four to six weeks before worker wasps begin to emerge.
Spring Wasp Nests Are Very Small
In April, a wasp nest is usually no bigger than a walnut or golf ball. Because the queen is working alone, there is usually very little visible activity around the nest.
This is why early wasp control is much easier than dealing with nests in summer when colonies are much larger.
What Wasps Eat in Spring
Unlike late summer when wasps search for sugary foods, spring wasps are mainly focused on hunting insects.
Common prey includes:
- Flies
- Caterpillars
- Aphids
- Small insects in gardens
At this stage they can actually help reduce garden pests, although nests close to homes or buildings may still require professional wasp control.
When Worker Wasps Start Appearing
After a few weeks, the queen’s first eggs develop into worker wasps. These workers take over nest duties such as:
- Expanding the nest
- Gathering food
- Protecting the colony
Once workers emerge, nest growth accelerates quickly.
By late summer, a single nest can contain several thousand wasps.
Are Wasps Aggressive in Spring?
Wasps are generally less aggressive in early spring because there are no workers defending the nest yet.
However, queen wasps may still sting if disturbed while building their nest. If you notice a nest forming in a loft, shed, or wall cavity, it is best to consider early wasp control to prevent the colony expanding.
Why Early Wasp Control Matters
A nest started in April can grow rapidly over the following months. By mid-summer, nests can contain thousands of wasps, making treatment more difficult.
Early wasp control helps:
- Prevent large colonies forming
- Reduce the risk of stings
- Protect homes, businesses, and outdoor spaces
Identifying nests early is the most effective way to manage wasp activity during the warmer months.
Common Questions About Wasps in Spring
Do wasps build nests in April?
Yes. April is when queen wasps begin building new nests after emerging from winter hibernation.
Are the wasps seen in spring queens?
In most cases, yes. The majority of wasps seen alone in early spring are queen wasps starting new colonies.
Are spring wasps dangerous?
Spring wasps are usually less aggressive than summer wasps, but they can still sting if disturbed.
When should wasp control be arranged?
Wasp control is most effective as soon as a nest is noticed, especially early in the season before the colony grows.
