Pest pressure changes through the year. Knowing what's coming makes prevention far easier - and cheaper - than reacting to an infestation. Here's what to expect across the seasons in Suffolk and East Anglia.
Spring (March–May)
As temperatures rise, overwintering insects become active and rodents that bred indoors look for food. Ants begin foraging and the first wasp queens emerge to start nests. Now is the time to proof entry points and tidy waste areas before populations build.
Summer (June–August)
Peak season for flying insects. Wasp nests reach full size and become aggressive later in the season; flies multiply rapidly in warm weather and are a major risk for food businesses. Cluster flies, fleas and ants are all common. Fly screens, good waste management and prompt wasp-nest removal are key.
Autumn (September–November)
The big one for rodents: as the weather cools, rats and mice move indoors looking for warmth and food. This is the most important time of year to have proofing and monitoring in place - a small autumn problem becomes a winter infestation fast.
Winter (December–February)
Rodents are well established indoors and mice continue to breed year-round in heated buildings. Stored-product insects can persist in warm storage. Ongoing monitoring catches activity early, and it's a good time to review proofing for the year ahead.
For businesses
A year-round monitoring contract smooths out these seasonal spikes and keeps you continuously protected - with the documented records inspectors expect. Commercial rodent contracts start from £60/month.
FAQs
- When are rats and mice worst in the UK?
- Autumn is the peak, as cooling weather drives rodents indoors for warmth and food. In heated buildings mice breed year-round, so winter activity is common too.
- When is wasp season?
- Wasp nests build through spring and summer, reaching full size and becoming most aggressive in late summer (August–September).
