Signs of Infestation:
If you have a yellow jacket infestation there aren't many signs that point to it. The most obvious sign is seeing these wasps gathered in one place. If you see a nest, this will also be a sign of an infestation. Always be cautious if you see a nest nearby. There could be thousands of these social wasps living in a colony. These pests are known to be aggressive and will attack if they feel threatened. They can sting you multiple times as well. For those who are allergic, their stings can also be severe. If you have these pests roaming around the outskirts of your home, contact a pest technician who can safely remove the nest and wasps.
