The yellow jacket is the biggest threat when it comes to stinging insects. They are the most aggressive species of stinging insects with the ability to sting multiple times. Yellow jackets are social insects that live in nests built either in the ground or in the eaves or attics of people’s homes. Like hornets and wasps, they build their nests out of wood and plant fibers they chew up to make a paper-like nest. Similar to most stinging insects, they are yellow and black and about 1-inch in length.
They are one of the few stinging insects that do not collect pollen. They primarily prey on smaller insects, but it is not uncommon to find them eating human food. Yellow jackets are typically the insects that interrupt your picnics because they are attracted to sweet foods like juices and fruit.
