Yellowjackets have large abdomens, with a very thin waist. Their bodies are black and bright yellow. They’re ⅜” to ⅝” long, although the queens are generally larger.
Yellowjackets are aggressive insects, and are best left alone until they can be addressed by a licensed professional. Their nests look like paper cartons, because they’re made of a similar material -- chewed up and regurgitated cellulose. Yellowjackets are common pests at parties and outdoor barbecues because they’re attracted to sweet foods. A 4th of July Barbecue isn’t complete without a few yellowjackets in your fruit salad! Yellow jacket infestations are often not taken seriously enough, as their stings can cause severe reactions for those who suffer from sting allergies. Insect stings send over 500,000 people to the hospital every year. To avoid attracting yelowjackets, take your garbage out often, don’t wear strong perfume, and most importantly, contact a professional if you suspect you have an infestation.
