How to Identify:
Wasp – Identification and Treatments. There are around 75,000 species of wasp in the world whose appearance varies widely, though all have two wings and a “waist” between their two body segments. Most are yellow and black but come in many other colors such as green or blue. Wasps can be any where from less than 1mm to 75mm. Some wasps live in colonies which can number in the thousands while others are solitary. Wasp colonies construct nests on tree limbs or in the corners of buildings. Wasps can be aggressive when they feel threatened and, unlike bees, can sting multiple times.
Some species of wasps are predatory: they kill and consume other insects and feed them to their young. Others are parasitic: they lay their eggs inside other living creatures and their larvae feeds on the still living host. Both types of wasp can be helpful in controlling populations of other nuisance pests. Some species also feed on flower nectar and are useful pollinators. Wasps can even be scavengers who eat meat and sugary substances; they sometimes become nuisances near outdoor trash cans. Most wasps construct nests made of wood pulp or mud in which their colonies reside. The queen wasp produces all the eggs and hides in a sheltered area during the winter when most of the colony dies out. Come spring the queen starts laying eggs again that will become workers to rebuild the nest.
How to Stop Them:
Since wasps are beneficial predators and pollinators, it is best to only remove them if they pose a stinging threat to humans or pets. One way to prevent wasps from coming near your home is to keep all trash cans closed and clean so they don’t have a food source. It is dangerous to try to remove a wasp’s nest on your own because this could create swarming activity. Multiple stings of some species of wasp can be dangerous to your health, especially if you have an allergic reaction. The safest option is to contact a pest control professional to handle the situation.
