Take Caution: Situations and Advice Regarding Stinging Insects

In discussions with our clients, sometimes we run into some common situations that require some advice regarding stinging insects. With your family’s safety in mind, we are taking this opportunity to highlight some of those frequently visited circumstances and offer some helpful solutions.

Situation: Using a pressure washer or hose to spray down an active stinging insect nest around your home.

What Happens: Flooding a nest with water may make the nest fall, but typically it will not kill the insects, at least not all of them. It will however make them more aggressive and potentially cause an attack in response. Doing this may also flooding or water damage to areas around your home. The remaining stinging insects will rebuild the nest in a nearby location soon after you destroy their nest.

Solution: The nest needs to be treated before it can be knocked down or removed. For safety reasons, it’s best to have a licensed and certified technician perform the treatment.

Situation: Plugging entrance holes in an active stinging insect nest.

What Happens: It’s a common misconception that by simply plugging the doorway to a nest, the insects will simply leave and move on. Some may even go as far as treating the nest with a store bought liquid insecticide and then plugging the hole directly afterward. What really occurs is that the insects, by using light as a guide, will easily find another way to enter and exit the nest. Sometimes the new entrance ends up being in an even worse location, such as when a plugged outdoor entrance causes the insects to create a new entrance, which leads them into your home. You will also find that the stinging insects will also grow more aggressive if you block their entrance.

Solution: If you want to have the nest professionally treated, you may need to revisit the nest in the evening (when it is safest) to unplug the entrance hole so that nest can be treated through that access point. When a professional treats a nest, the product used will penetrate the nest more deeply and tend to be effective on the first application. If the nest is professionally treated, it should not be plugged or removed until completely certain that the nest is in an inactive state.

Bonus Situation: You’re walking around your yard and stumble onto an active ground bee nest.

Solution: Ground bee nests are easier to spot than you think. Regularly check your yard for conical shaped holes with piles of dirt surrounding them. Sometimes several holes can be found relatively small area. If you do find nests in an unsafe area, avoid them and give a professional a call for control and treatment advice.
