You are more likely to encounter wasps between late July and early October, as this is when the amount of sugar produced by wasp larvae in the nest is reduced. This forces wasps to leave their nest to find other sources of sugar, such as human food. Wasps do not see your home as a place they are intruding, but merely as another location for them to potentially nest. If you start to notice a rise in numbers around your home, there is a good chance that a wasp nest is being constructed, or they are scouting the location to see if it is suitable. When it comes to their stings, there is an important distinction to be made between bees and wasps. Honeybees die after they have used their stinger, which is most likely to happen when a female thinks there is a threat to the hive. However, like hornets, wasps can use their stinger several times without it having any effect on them.
