Paper wasps are semi-social insects, they will sting to protect their colony, releasing toxins that can be harmful. Wasps can sting repeatedly causing pain, swelling and whole-body effects that can trigger allergic reactions. They do not store food and they eat insects and spiders. Forager wasps bring morsels of food back to the nest from time to time. This is unloaded by one or more wasps at the nest which is then distributed to several other wasps that partake of some of it themselves, and offer the rest to the larvae, distributed all over the nest. Non-random space use allows wasps that exchange food with each other to be located close to each other, making food distribution more efficient.
