Advice for controlling Wasps

Professional Wasp Nest Treatment

A pest controller will typically apply an insecticide near the entrance of the wasp nest. Wasps then carry the chemical inside, which kills the colony over a few days. If the nest is in a hard-to-reach area, professional pest control companies have specialised tools to safely reach and treat it. If desired, you may request that the pest controller return to remove the nest for an additional fee. Alternatively, you can remove the nest yourself in autumn or winter when all wasps are dormant. Ensure you wear protective clothing if the nest has been treated with pesticides.

DIY Wasp Control – Considerations

While insect sprays can kill individual wasps, they are ineffective against established nests. Many DIY nest removal methods found online are unsafe. Wasps can release a distress pheromone that attracts other wasps, leading to multiple stings. While small nests may be manageable in early spring, handling a large nest without professional help is risky, particularly if you are allergic to stings.

Why Use Professional Wasp Control?

Professional pest controllers have access to effective insecticides and protective equipment, enabling safe wasp nest removal. BPCA-registered companies adhere to the highest safety standards, providing you with peace of mind and safe solutions for wasp control.

Recognising a Wasp Nest

Wasp nests are often built in sheltered areas such as lofts, wall cavities, and sheds. Nests start small in spring, about the size of a golf ball, and can grow to a substantial size by late summer. Wasps typically build nests using chewed wood and saliva, creating a durable, lightweight structure.

• Under trees
• In bushes
• In wall cavities
• Under eaves
• In sheds or garages

Treating Wasp Stings

If you experience difficulty breathing or dizziness after a wasp sting, seek immediate medical attention. For minor stings, wash the area, apply a cold compress, and use antihistamine cream. Avoid scratching, and consult your pharmacist for additional treatments if needed.

When Not to Treat Wasp Nests

Wasp nests should only be treated if they pose a risk to public health and safety. Wasps help control garden pests by feeding on insects like caterpillars. If a nest is not near human activity, it may be best left undisturbed.

“Where possible, it is worth leaving wasp nests to continue their valuable activities. However, there can come a time when the presence of wasps is detrimental to public health.” — Natalie Bungay, BPCA Technical Officer

Preventing Wasp Nests

Prevention is key. To minimise wasp activity:

• Secure windows and doors to prevent wasps from entering.
• Keep bins closed to avoid attracting wasps with food waste.
• Check common nest locations in early spring when nests are small.

Contacting a Professional

For safe and effective wasp control, consider contacting a professional pest controller. BPCA-registered companies meet all legal and safety requirements, ensuring that your wasp problem is handled professionally.
