Although bees provide the useful service of pollination and help control populations of other insects, they can also cause problems. Bees and people don't typically get along because many bees (though not all) deliver nasty stings that can even be fatal if a person is allergic. Many insecticides available on the market will effectively eliminate an entire bee colony overnight. One of the most common is carbaryl, sold under the brand name Sevin dust. Sevin is available at most garden supply stores and can be used as an effective killing agent against bees. Sevin is powerful and easy to use.

Things you need
- Sevin dust with 5-percent carbaryl
- Air compressor
Purchase Sevin dust at your local garden supply, home centre or feed mill. Get dust with a 5-percent concentration of carbaryl. You'll use an air compressor to apply the chemicals.
For ground bees, locate all entrances to the bee's nest. There may be one main entrance and other smaller entrances and escape hatches. You'll be able to tell which holes are entrances because the bees will fly in and out of them during the day. Other bees nest in hollow wood, wall cracks, on trees and other such places.
Approach the bees' nest in the evening after the sun has set. Bees are less active when temperatures are lower. Wear a pair of slacks, sneakers and a long-sleeved shirt to avoid exposing your skin to painful stings. You can use a red flashlight because, interestingly, bees cannot see red.
Standing about 8 feet from the nest, spray the dust into the nest's entrance. Place the compressor funnel inside the hole and pump it about four times.
Head inside and wait until the morning. You should see a substantial number of dead bees in the vicinity, though the dust may not have killed all of them. To finish the job, wait two more days and repeat the process again. For ground nests, you can cover the entrance hole with soil or place a rock over it.
Tips and warnings
- You can also try liquid Sevin or other liquid-based insecticides.
- Be extremely careful when dealing with Sevin dust. Do not spray if there is significant wind or if there are children and pets around. Wear a protective mask to avoid inhaling the dust.
