But, if the nest is located where people may be stung or if you are allergic to the stings, then you will probably need to destroy it. Pressurized wasp and hornet aerosol sprays are readily available in stores. These sprays can project a stream of material 8 to 10 feet. They work extremely well on wasp and hornet nests since you can spray them from a safe distance and most of them have immediate “knock down” power. But, don’t use these sprays around desirable plants or shrubbery since they have a petroleum base and will burn the leaves they contact.
Sevin dust, which we commonly use in our vegetable gardens, is also very effective on bees and may be a control option depending on where the nest is located. For instance, it works well when applied to the entrance of a yellow jacket’s nest in the ground. But, be careful, when using Sevin dust, since it will not kill them immediately upon contact like some of the aerosol sprays. Do not pour gasoline or other petroleum down a nest hole. This is illegal and dangerous to you and the environment; plus, at today’s price, it is expensive.
It is usually best to carry out most control methods in the late evening hours just prior to dark. At this time bees are least active, and most of them are in the nest. Regardless of the control option you choose, you should be very cautious since most nests will contain very large populations of bees.
If a nest is in a wall or other inaccessible area in your home, you may want to hire a pest control company to do the work for you. It is best to remove the nest from the structure, especially if it is large since they can attract other insects.
