Hornets are actually a type of wasp. There are two obvious ways to tell a wasp from a bee. Wasps are slender and bees are plump, wasps are smooth skinned while bees will have hair. Another difference between the two is that bees will die after stinging. their stingers are barbed and will remain inside the victim as the bee tries to fly away after the sting. A wasp has a smooth stinger and can use it again and again. Wasps can become aggressive when agitated. It is best if you encounter a nest of wasps to call a trained professional to remove it.
Wasps nests can be found in a variety of places, in trees and shrubs, in abandoned burrows, under eaves, inside attic walls, behind shutters and in the ground. For more on Wasps Hornets and bees go to http//:www.catopestcontrol.com
