European wasps are a summer and early autumn problem across Bacchus Marsh, and the valley's old orchard land, timber retaining walls and rural fence lines give them plenty of places to nest. Unlike paper wasps, European wasps nest underground or inside cavities, so you often cannot see the nest, just a steady stream of wasps going in and out of one spot in a wall, a garden bed or a compost heap.
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 will chew a new exit into your house. If the nest is in a wall cavity or ceiling we tell you what to expect and when it is safe to open things up. We also treat paper wasp nests under eaves, on pergolas and in sheds while we are there. Please do not try to flood or block a European wasp nest yourself; the colony defends it hard.
