As warm weather takes hold here in Raleigh, you may see the occasional bee or a random wasp. However, spring is the time when they begin building nests, and if you see wasps in your home, it means the nest may be closer than you think. In fact, chimneys are one of the more common spots because they are protected and undisturbed. If you suspect there’s a wasp nest in your chimney, you need to take quick action because nests grow rapidly and wasps get aggressive to protect them. To help you eliminate this problem, we’re sharing how to kill the insects and get rid of the nest, plus ways to prevent them from coming back.
How to Get Rid of Wasps in a Chimney
Getting rid of a nest isn’t incredibly difficult, but it does require you to follow specific steps and guidelines to stay safe and do the task right.
What You’ll Need
- Powerful flashlight to see exactly where in the chimney the nest is located;
- Safety glasses or goggles to protect your eyes from both stings and spray;
- Face mask that covers your mouth and nose to breathing in the poison spray;
- Heavy work gloves and protective clothing – long pants, long sleeve shirt, boots – you want to cover any exposed skin and put a few layers between your skin and a wasp’s stinger.
- A long pole or a broomstick;
- Wasp spray that can reach up to 15 to 20 feet;
How to Kill the Wasps
First, it’s important to be aware of wasp activity and know they are more active when it’s warm. We recommend waiting until the temperatures are below 55 degrees to find and kill the wasps as they will be less active and less aggressive.
Put on your protective gear, including your goggles, gloves, and long-sleeves as you’ll be in the fireplace where a wasp may fly down. Once you’re covered, find where the wasps’ nest is located by shining the flashlight and looking up into the chimney. Most often, the nest is closer to the top, near the vent, but they will sometimes build further down, closer to the fireplace.
If the nest is close to the top of the chimney, you may need to get onto the roof with your wasp spray, preferably one like cypermethrin which is slow-acting and kills them as they live in the contaminated nest. Spray the nest thoroughly but carefully, taking care to not fall if you’re on the roof but being cautious that wasps may seek to leave the nest.
Check out the nest the next day to see if there is still activity, including live wasps flying or crawling around. If you do see activity, spray it again. This may take a few applications to thoroughly eliminate wasps. Once it’s done, knock the nest down from the inside of the chimney, taking care to dispose of it.
This method is best done with very small, beginning nests. Large, established nests should be removed by a professional pest control company.
Preventing Wasps’ Nests in Your Chimney
After you’ve gotten rid of the problem, the next step is making sure they don’t come back or that other wasps don’t take up residence. Some preventive measures include:
- Placing a thin, mesh vent screen over your chimney to keep wasps from flying in;
- Seal any cracks in your chimney with mortar or caulk to keep wasps from entering this way;
- Move trash cans and bird feeders away from the side of the home with the chimney to avoid attracting wasps in the first place;
- Consider using a decoy nest as wasps won’t build within 200 feet of an existing nest. Putting up a decoy will make wasps think there’s one that’s established and in use.
The number one way to prevent wasps in your chimney is to work with a pest control company in Raleigh that can provide regular pest and insect prevention. With a barrier spray around your home, pests, including wasps and bees, will stay away from your house.
