The problem with wasps is that they are far more aggressive and will attack with a lesser level of provocation compared to that of honey bees and bumblebees. Warm weather plays into their habits; wasps grow more quickly in warm weather, meaning they go through their generations more rapidly and the result is more wasps being produced in a given nest, leading to more wasps out hunting. This can be very problematic for humans and often calls for professional wasp control.
