There are several species of yellowjackets. These flying insects typically have a yellow and black head/face and patterned abdomen. Many say, the pattern resembles stripes. Signature to species, the abdomen pattern can help an entomologist or pest professional identify specific types of yellowjackets.
Yellowjackets can be found anyplace humans can be found. Check near recycling bins or other areas where sugars are common but keep in mind these pests also feed on protein. Yellowjackets become more aggressive in autumn when the colony begins to die out except for the queen.
Yellowjackets nest in the ground or in cavernous areas such as eaves, attics, etc…. They feed on sweets and proteins and commonly invade outdoor activities.
