Causes of Hornet Infestation

Serving Vancouver WA | Portland OR | Beaverton OR

Reasons Why You Have Hornets in POrtland OR and Vancouver WAHornets can be terrifying and for good reason. While they share the same species of insects as wasps, they are much bigger than wasps and are capable of delivering stings with a greater amount of venom that can be fatal.

The good news is that hornets are actually docile in comparison with wasps and are not interested in harming anyone unless they feel threatened.

If you have hornets, it may be a good idea to consider the reasons why you have hornets. It may not get rid of them, but it may help prevent them from returning again.

Hornet Nesting Locations

Hornets are much like humans when looking for a place to build their homes. They look for a location that will support the nest and allow them to go about their business. Some popular spots for hornet nests include:

  • Decking
  • In eaves of buildings
  • In treetops
  • Underground in abandoned rodent holes

When hornets build their nests above ground, they fashion a stalk called a petiole that is used to connect the nest to the object from which the nest hangs. This is how some nests are free-hanging.

Nests that are built underground, often in holes that were once occupied by rodents or rabbits, are especially dangerous. Accidentally stepping in one of these holes, or running over one of them with a lawnmower can agitate hornets and cause them to become aggressive.

What to Do If You Have Hornets

Regardless of the reasons why you have hornets, once you have them the main concern is getting rid of them. Because of the dangerous levels of venom that a hornet sting contains, it is not recommended that novices attempt to remove hornets on their own. Unlike other stinging insects such as honeybees, hornets do not die after inflicting a sting, so they can sting and sting yet again.

If you have hornets, the best course of action is to call in a professional exterminator. These professionals are trained in how to deal with hornets and, wearing protective gear, can eradicate them safely.

The good news is that once hornets leave their homes at the end of the season, they do not return to them, but seek new places to build next year.
