Which Stinging Insects Should you be on the Look Out for?

Stinging Insects

Stay safe and sting-free while enjoying the outdoors this summer by learning how to avoid the more aggressive insects such as Africanized honeybees, yellowjackets, and wasps. We’ll help you avoid the most common places where these insects like to nest and what to do if you find an infestation.

Stinging Insects

European hornets are large and aggressive and can damage foliage in your yard as they gather materials from shrubs and trees to create their nests. They’ll fly around at night, which makes them different from many other stinging insects.

  • Places to avoid: European hornets like to build gray, paper-like nests in openings and gaps in walls, as well as hollow trees.
  • What to do if you stumble upon an infestation: leave stinging insect control to the professionals. They are aggressive if they feel their nest is being attacked, and each nest can house hundreds of these hornets.

Baldfaced Hornets
Although called hornets, these pests are actually yellowjackets. They’re plentiful and are found nearly everywhere in the United States. They are helpful insects who eat insect pests like flies and are flower pollinators, too.

  • Where they live: Most baldfaced hornets live in bushes and trees, in gray, football-shaped nests.
  • What to do if you find a nest: If you find a nest on your property, call a stinging insect exterminator. These hornets can be aggressive when they feel that they are threatened.

Yellowjackets tend to build nests on trees and buildings as well as in the ground. They are slower to sting unless their nest is threatened. Yellowjackets are capable of stinging multiple times. Of the 16 different species of yellow jackets, the most common one is found in every state.

  • What to avoid: At barbecues, cover food and clean up by properly disposing of garbage (particularly sweets and proteins).
  • How to get rid of a nest: Just as with other stinging insects, let the pest control professionals remove yellow jacket nests using the proper equipment and experience.

Paper Wasps
You may notice paper-like nests shaped like an umbrella on twigs and branches of trees and shrubs as well as porch ceilings, eaves, and attic rafters. Those are the work of paper wasps who have carefully chosen these covered spaces to build their nests.
Humans are at risk of wasp attack when they accidentally contact the nest. Like yellow jackets, wasps can sting more than once. In defending their nest, they will use alarm pheromones to call for back up.

  • Places to avoid: shrubs, hedges, fruit trees, plants, wood fences, deck railings, etc.
  • How to get eliminate: You can treat wood fences and deck railings with a repellent oil to minimize the chances of these unwanted insects. But if you find an infestation or single nest, contact a licensed pest control professional to remove and treat for wasps.
