Wasp report September 2009

One of the driest and warmest Septembers for a decade, and a record September for wasp activity and stinging incidents.

At this time of year wasps are at their most aggressive in their hunt for food, the foraging wasps are able to keep a higher proportion of the food they gather for themselves leading to ‘drunken’ incidents when fruit ferments inside them. The environment inside the nest is at its worst due to overcrowding, and overheating on hot days.

These conditions lead to many unpleasant incidents with wasps when in contact with humans, either due to accidental contact with wasps too drowsy to keep a distance, or aggressive behaviour by the wasps in their hunt for food.
