The most common species are the Lesser Banded Hornet (Vespa affinis), Yellow-vented Hornet (Vespa analis) and Paper Wasp (Polistes sagittarius). Paper wasps are found most frequently in residential properties, building open umbrella-shaped nests under eaves, ledges and inside letterboxes.

Key signs include a visible grey papery nest structure under eaves, inside roof voids or in dense vegetation; a steady stream of wasps or hornets flying in and out of one spot; wood-scraping damage on timber surfaces; and unprovoked aggressive behaviour from wasps flying at you without obvious reason.

Yes. Unlike honeybees, wasps and hornets can sting multiple times without dying. They also release alarm pheromones that recruit the entire colony to attack simultaneously. Hundreds of people die each year from allergic reactions to their venom. Even people with no prior allergy history can develop anaphylaxis from a large number of stings.

We strongly advise against DIY nest removal. Disturbing an active nest without proper protective equipment and professional-grade insecticides typically triggers a mass attack. A large hornet colony can deliver hundreds of stings in seconds. All nest removal in Singapore should be performed by NEA-licensed professionals.

Treatment is most effective in the early morning or after sunset when the colony is least active and most workers are inside the nest. Wasps and hornets are most active during the warmer parts of the day especially in late spring and summer when they forage for food and expand their colonies.

A standard nest removal treatment takes approximately 30 to 60 minutes depending on the size, location and accessibility of the nest. Our technician will assess on-site and advise accordingly. Larger or hard-to-reach nests may require a follow-up visit to confirm complete elimination.

After a successful nest removal, surviving foragers may return briefly to the nest site before dispersing. This is normal and usually resolves within 24 to 48 hours. Our treatment includes sealing entry points where possible. If a new nest forms within the warranty period, we will return at no extra charge.

Yes. After every service, our technician generates a digital service report through our app. This records all pest species identified, treatment areas covered, products used and any recommended follow-up actions. You receive a complete digital record every time — no paperwork required.
