WITH temperatures climbing across the region, pest controllers are warning that wasp season has officially begun.

The warm weather has triggered an early surge in activity, with queen wasps emerging to scout for food and begin nest-building in sheds, lofts, roof spaces and wall cavities.

Local firm Venables Pest Control stated on social media: “Warmer Weather = Wasp Season is Back! As the temperatures begin to rise, wasps start becoming more active scouting for food and building their nests.”

Wasps are highly active scavengers, feeding on fruits such as apples, pears and plums, and will strip wood from fences, sheds and garden furniture to build their distinctive paper-like nests.

While they play a role in pollination and controlling other insect populations, wasps can become a serious nuisance, especially towards the end of summer when they stop feeding larvae and instead focus on sugary foods.

This shift often brings them into conflict with people, particularly in kitchens, bakeries, pubs and outdoor eating areas.

The main concern, however, remains their sting. A wasp’s sting is haemolytic, haemorrhagic and neurotoxic. It can cause swelling, redness and pain—and in some cases, more serious reactions.

Stings to the throat can lead to breathing difficulties, while those with allergies may suffer from anaphylactic shock, which includes symptoms such as faintness, itching, facial swelling, vomiting and abdominal pain.

Although wasps seen inside the home can often be dealt with using aerosol sprays, active nests should only be handled by trained professionals.

Nests are typically located by carefully observing wasp flight paths, and are treated using insecticidal powders, smoke or liquid sprays—always while wearing full protective clothing.

Residents are being urged to act early if they suspect a nest on their property, as nests can expand rapidly and become more difficult to manage as the season progresses.
