Wasp season in the North West runs from late spring through to early autumn, with August and September typically being the most active months. If you've found a wasp nest in your home, garden, or business premises, this guide will help you understand what to do — and what not to do.
Wasp colonies begin to build in spring when the queen emerges from hibernation and starts constructing a small nest. By midsummer, a healthy colony can contain 5,000–10,000 workers. In late summer, the colony produces new queens and males, and the workers — no longer focused on feeding larvae — become more aggressive and are more likely to sting.
In Merseyside and Cheshire, wasp activity typically peaks between late July and mid-September. This is when most calls to pest controllers come in, and when the risk of being stung is highest.
Wasps build their papery nests from chewed wood pulp. Common nesting sites include:
Roof spaces and loft insulation — one of the most common locations in UK homes.
Wall cavities — wasps enter through small gaps in brickwork or around window frames.
Garden sheds and outbuildings — particularly in undisturbed corners and roof spaces.
Underground — some species, including the common wasp, nest in old rodent burrows in gardens and verges.
Trees and hedges — aerial nests are less common but can be large and highly active.
We strongly advise against attempting to remove a wasp nest yourself. Here's why:
Wasps are aggressive when threatened — unlike bees, wasps can sting multiple times and will defend their nest vigorously. Disturbing a nest without proper protective equipment can result in hundreds of stings, which can be life-threatening even for people without a known allergy.
Blocking the entrance doesn't work — if you block the entry point to a nest, wasps will find or create alternative exits — potentially into your living space. This is one of the most common mistakes homeowners make.
Over-the-counter products are often ineffective — shop-bought wasp sprays are designed for individual wasps, not established nests. They rarely penetrate deep enough into the nest to kill the queen, meaning the colony will recover.
A professional pest controller will apply a fast-acting insecticide dust directly into the nest entrance. The workers carry the dust into the nest, where it kills the colony within a few hours. The treatment is quick, effective, and safe when carried out by a qualified technician.
In most cases, the nest does not need to be physically removed — once the colony is dead, the nest will not be reused and will naturally deteriorate over winter.
- Do not panic — a wasp nest that is not disturbed is generally not dangerous
