Not every buzzing insect in your garden needs treatment. In fact, getting the identification right is one of the most important first steps before calling anyone out. Bees are protected and beneficial, hornets need careful handling, and wasps are usually the genuine problem. Here’s how to tell what you’re actually dealing with, based on the calls our Northampton Pest Control team gets every summer.
Common wasps (Vespula vulgaris)
This is the classic black-and-yellow striped insect most people picture when they hear “wasp”. Key features:
- Bright yellow with sharp, well-defined black bands
- Smooth, shiny body with a narrow “waist”
- Around 12–17mm long
- Aggressive when disturbed, especially in late summer
Common wasps build papery, grey-brown nests resembling a layered football. You’ll find them in lofts, sheds, wall cavities, and underground in old rodent burrows. A mature nest can house several thousand wasps by August.
German wasps (Vespula germanica)
Almost identical to common wasps to the untrained eye, but with three small black dots on the face instead of the anchor-shaped marking of the common wasp. Behaviour and nest type are very similar, and treatment is identical.
European hornets (Vespa crabro)
Often mistaken for giant wasps, hornets are increasingly common in Northamptonshire. Key features:
- 25–35mm long — noticeably bigger than wasps
- Brown and yellow rather than black and yellow
- Deeper, louder buzz
- Often active at dusk, which wasps generally aren’t
Despite their fearsome reputation, European hornets are actually less aggressive than common wasps. They will, however, defend a nest vigorously and their sting is more painful due to the larger venom load. Nests are typically built in hollow trees, outbuildings, and chimneys.
Honey bees
Honey bees are smaller than wasps, golden-brown rather than yellow, and noticeably fuzzy. They have a more rounded body shape without the wasp’s sharp waist. Crucially, honey bees are pollinators and are not treated by reputable pest controllers. If you have a honey bee swarm, contact a local beekeeper through the British Beekeepers Association — they’ll often collect the swarm free of charge.
Bumblebees
Large, very fuzzy, and almost always docile. Bumblebees nest in small numbers (50–400 individuals) and the colony dies off naturally each autumn. They almost never need treatment, and most species are in decline, making protection important.
Solitary bees
Mason bees and mining bees often appear in brickwork or lawns. They look bee-like but live alone, don’t form colonies, and rarely sting. Leave them be — they’re excellent pollinators.
When to call in the professionals
If you’ve confirmed you’re dealing with wasps or hornets, and the nest is anywhere near a high-traffic area — a doorway, garden, children’s play area, or business premises — it needs professional treatment. Trying to wait it out rarely works: wasp colonies grow throughout summer and become more aggressive into August and September as food sources dwindle.
