There is a specific time of year when wasps become more aggressive than usual.
During the last months of summer, the normal social structure of wasp nests breaks. Priorities change and instead of raising workers, their aim becomes raising queens, which will hibernate and create new colonies the next year.
At this time, the hormone which maintains colony cohesion is no longer produced, resulting in disoriented wasps looking for sweets like a glass of your favourite juice.
