How to Get Rid of Wasp Nests on Houses

Wasps that build nests too close to humans should be eradicated.

Wasps are beneficial to the environment because they eat insects and spiders. They mate and build nests in the spring. Wasps like to build their paper nests in protected places, such as in window frames, doorways and under the eaves on a house. They usually don't bother humans unless they are bothered first. If they think they or their nest is in danger, look out! Wasps can sting you over and over, which makes an attack worse. It's a good idea to immediately eradicate any wasp nests you find on your house.

Things You'll Need

• Long-sleeve shirt
• Pants
• Socks and shoes
• Gloves
• Face veil
• Safety goggles
• Flashlight
• Red plastic wrap
• Wasp spray

Instructions

1. Protect your entire body from wasp stings. Wear a long-sleeve shirt, pants, socks and enclosed shoes, gloves, a face veil and safety goggles.

2. Wrap a piece of red plastic wrap over the end of a flashlight. Wasps are attracted to light, but they won't see the red light.

3. Locate the wasp nests on the house. Walk around the perimeter, paying special attention to the windows, doorways and roof eaves.

4. Locate the entrance of the wasp nest. Don't stand directly underneath the nest; stand to the side. Spray the entrance to kill them. If any wasps do emerge, you can spray them directly. Spray the rest of the nest until it is saturated. Repeat this step with any remaining nests you found.

5. Check the wasp nests on the house the next day. If there is still activity, repeat the steps to kill them. If not, knock the nests down.

Tips & Warnings

• Deal with wasps in the evening hours. This is when they are the most inactive. They will all be inside the nest at that time too. And, the darkness will help give you cover.

• Read and follow the label directions, as well as the warnings, on the wasp spray can before use.

• Choose a wasp spray that has an adequate spray range to reach the nests on the house. You don't want to start spraying and not be able to reach the nest.
