Finding a wasp nest in the garage can be a startling and dangerous situation. Many individuals are allergic to the venom of wasps, and might not even know until stung. Depending on the type of wasp and the placing of the nest, calling a professional to take care of the removal might be the best option. However, for those who prefer to try it themselves, there are safety tips to follow and a few steps that will make the process much easier.

Wasp nests can be dangerous, especially in a garage attached to the house.

Step 1

Prepare the area. If the garage is attached to the house, make sure all the doors and windows into the house are closed. With any removal process, there is always the chance of disturbing the wasps and making them more aggressive than usual as they attempt to defend their home. Make sure children and other family members are out of the garage and well away from the surrounding areas outside. Put pets in the house to keep them from being stung as well.

Step 2

Wait until night. Wasps are much less active at night, making the removal process easier. Depending on the time of year, it also may be worth waiting for the weather to turn cold. If the garage is unused or unneeded and it's getting close to winter, consider waiting. Cold weather will kill wasps, making the nest easy to remove.

Step 3

Set up traps. These can greatly decrease the number of wasps swarming around the nest when it's finally time to remove it. The most effective lure traps can be found at hardware stores, and generally will be successful at removing a large number of the wasps. Depending on the size of the nest, it might be beneficial to get several traps. Homemade traps can also be effective. Fill a large bucket halfway with water. Above the water, suspend the bait; some kind of meat typically works best. After feeding, the wasps will instinctively fly down into the water, where they will die. The bait may need to be changed every few days. Sealing the garage will help keep outside pests from coming in. Depending on the size of the nest, this may take several cycles of setting traps to put a serious dent in the colony's population.

Step 4

Put on protective clothing and spray the nest. There are a variety of commercial wasp and hornet sprays available at hardware stores. Most nests have an entrance hole where the insects come and go. By the time the traps have done their work, it should be possible to get close enough to the nest at night to spray it. This, too, can be done several times. If the nest is inside a workbench or other secluded area, it may be possible to spray the entire area with the pesticide, then close the cabinet doors to let the pesticide do its work. Alternatively, seal the garage after spraying the insecticide to ensure maximum effectiveness.

Step 5

Between the traps and the spray, most of the wasps should be gone, so it's time to remove the nest. If it is in an area that isn't easily accessible, laying down a tarp and breaking the nest off by hand is a possibility; be sure to wear heavy protective clothing. If the nest is in a corner or within reach, slip a heavy-duty garbage bag over the nest. Break it off, then zip tie the bag.
