As the colder months approach, many homeowners assume that wasp trouble is over for the year. In fact, winter is a crucial period when the groundwork for next spring’s wasp activity is being laid. By taking a few proactive steps now, you can greatly reduce the chance of a wasp nest forming on your property next season.
Why Winter Matters
During winter, only the queen wasp survives. She hibernates through the cold months and then emerges in spring to build a new nest. Fertilised queens seek sheltered areas such as lofts, wall cavities, sheds and garages to overwinter safely. Since old nests are never reused, reducing potential hiding and nesting spots now can make a big difference once spring arrives.
What You Should Do This Winter
Inspect and seal potential entry points
Check lofts, eaves, roof spaces, sheds, garages and outbuildings for any small gaps or holes. Seal these with foam, sealant or steel wool to stop queens finding a warm crevice. Pay particular attention to fascia boards, soffits and guttering, as these are common access points.
Tidy up around the garden and property
Clear away fallen fruit, ripe berries, compost piles and decaying vegetation. Wasps are attracted to sugary sources late in the year, so removing these helps discourage activity. Tidy up piles of wood, leaf litter and debris near walls or fences which could shelter hibernating queens.
Remove old nests and inspect regularly
Even though wasps won’t reuse an old nest, their presence shows the area was suitable before. Removing these nests makes it easier to spot new ones next year and reduces attraction. Always wear protective clothing when handling old nests or contact CSS Pest Services to handle this safely.
Monitor early spring activity
When the weather warms up in March or April, queen wasps start looking for nesting sites. If you notice a single wasp repeatedly flying into the same spot, or small papery material being built up, act quickly. A small early nest is far easier and cheaper to treat than a mature one later in the season.
Why Professional Help Is Worth It
Some nests are in awkward or hidden places like roof voids or behind cladding. DIY treatments can be dangerous and often only disturb the wasps without solving the problem. CSS Pest Services technicians are BPCA certified and use the correct equipment and treatments to remove nests safely and effectively. Booking a professional inspection before spring gives you peace of mind and helps avoid larger infestations later.
Quick Winter Checklist
- Seal any cracks or gaps in walls, roofs and sheds
- Clear away fruit, debris and garden clutter
- Remove old nests safely or arrange a professional visit
- Keep unused sheds and lofts closed through the winter
- Watch for early spring activity and act quickly if you see it
By taking these simple steps now, you can prevent wasp problems next spring and enjoy the warmer months without the stress of nests forming around your home
