When the weather cools, some harsh truths emerge. It’s not just sadness in saying goodbye to warm, sunny days, but also the sting — literally — from wasps and hornets.
As the season changes and these flying pests are facing their demise, they get a little cranky and more likely to sting. But just like many other pests, they do have a purpose in our environment, and at Northwest Pest Control we like to give credit where it’s deserved.
First, let’s take a closer look at these stinging insects. Hornets are actually a subset of wasps. In fact, wasps includes yellow jackets, as well as hornets. The hornet species is the largest and most aggressive of the wasp family. That’s where that phrase “mad as a hornet” comes from. A hornet can be 1 to 2 inches in length and is stocky in shape while wasps are half that size and have more elongated bodies. Both are black and yellow, but wasps appear shiny while hornets do not.
Wasps and hornets live in nests often in trees. Wasp nests are papery and can also be located under eaves, or in the case of yellow jackets, underground. Hornet nests are sometimes found in bushes and are spherical and fully enclosed, unlike the open nests of some other wasp species.
While other insects sting, wasps and hornets are one of the only type that can sting multiple times especially if they feel threatened or are defending their nests. The venom of both can cause pain, swelling, and allergic reactions, but the hornet’s venom is the more powerful and will cause the most discomfort to its victims.
Let’s step away from the downside of wasps and hornets and instead look to the benefits they provide to the environment and the important role they play in our ecosystem.
Pollination
Some hornets and many wasps are pollinators. Although not as efficient as bees, they also visit flowers for nectar and transfer pollen as they go. There are even wasp species that are specialized pollinators like fig wasps that help reproduce fig trees.
Pest Control
Both wasps and hornets are predators of other insects which helps maintain balance in our ecosystems. By preying on caterpillars, flies, aphids and other pests, they help control potentially harmful insects and prevent disease outbreaks. Plus they reduce the need for chemical pesticides.
Soil Aeration
As ground-dwelling yellowjackets create their underground nests, they are helping to aerate the soil allowing air, water, and other nutrients to reach plant roots. The nesting action of yellowjackets improves soil health, in turn, improving plant growth.
Ecosystem and Biodiversity Support
Some species of wasps, such as yellowjackets, are scavengers, feeding on decaying organic matter, including dead animals. Their appetites contribute to the decomposition process and help recycle nutrients back into the ecosystem. Turning the tables, wasps and hornets are prey for birds, reptiles, spiders, and other animals. Their presence in the food chain supports wildlife and overall biodiversity.
Despite the benefits wasps and hornets offer, they are still unwelcome guests to your home and yard. If you find nests in your trees or under your eaves, contact us.
We are experienced at removing wasp nests safely and taking the potential for painful stings out of your way. Even though wasps are underappreciated for their positive impact, we understand they have a proper place and that’s not in the direct path of people.
