European wasps are a summer and early autumn problem across Eltham and the Nillumbik bush suburbs. The stone walls, the sleeper garden beds, the firewood stacks everyone keeps, the mudbrick wall cavities and the banks along the creek all give them somewhere to nest, and the orchards and vineyards up through Panton Hill and Kangaroo Ground feed them. 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.
