As their name implies, yellowjackets are yellow and black. While yellowjackets are important predators of insect pests, sometimes they nest in less than ideal places.
We received a call from the manager of an apartment complex. Yellowjackets built a nest inside the exterior wall of the workout room of the complex. They were entering the wall through a hole around the steel plate of the outer door.
When away from their nest, yellowjackets are very slow to sting. However, they are territorial, and they become very aggressive when their nest is approached or bothered. They will sting threats to their nest, even multiple times. That's a bit of a problem when the nest is in a building wall near a door.
We arrived at the apartment complex early in the morning when it was nice and cool so that the yellowjackets would not be as active. As soon as the sun starts coming up and they get warm, they are more active. We wore bee suits to protect us against stings. We cut a three-foot square area in the interior wall to locate the nest, remove it, and kill all the yellowjackets. It was a three-layer nest. Yellowjackets of the type we removed build their paper nests in the ground or other protected areas.
If you have yellowjackets or other wasps, contact us, and we'll remove them for you.
