European wasps are the biggest call we get from January to April across Sunbury and the Macedon Ranges. The old stone walls and bluestone cottages, the sleeper garden beds, the firewood stacks, the rural fence posts and the dam banks all give them somewhere to nest, and the vineyards and orchards up the ranges give them food. Unlike paper wasps, European wasps nest underground or inside cavities, so you usually cannot see the nest, just a steady stream of wasps in and out of one spot.
Our tech finds the entry point, treats the nest with an insecticidal dust at the right time of day, and the colony is dead within a day or two. We do not seal the entry until the nest is finished, because a sealed live nest chews a new exit, sometimes into the house. Nests in wall cavities, roof voids and under decks are handled the same way and we tell you when it is safe to open things up. Paper wasp nests under eaves and on pergolas get treated while we are there. Please do not try to flood, burn or block a European wasp nest yourself; the colony defends it hard and the stings add up fast.
