PEST CONTROL TORONTO | WILDLIFE CONTROL SERVICES HAMILTON – CONTROL OF NESTS
Control of Nests
The first step in wasp or bee control is to correctly identify the insect and locate its nesting site. An experienced Pest Control may provide wasp or bee control service or you can use the following information to attempt to control them yourself.
The best time of the year to control wasps is in June after the queen has established her colony and while the colony is still small. But because nests are small, they are also harder to find. The best time of the day to control wasp nests is at night, when they are less active.
Exposed wasp nests
Wasp nests that are visible and near human activity can pose a potential problem. If there is a concern about stings, you should eradicate the nest. Apply a ready-to-use aerosol “wasp and hornet spray” into the entrance of the nest during late evening according to label directions. To avoid pesticide falling down on yourself do not stand directly under the nest and spray up. Plan your escape route. Be very careful if you must climb a ladder. If live wasps are still observed the next day, repeat the treatment.
Mechanical control without insecticides is possible for small, exposed nests. At night, cover the nest with a large, heavy, plastic bag and seal it shut. Cut the nest from the tree and freeze it. Use caution: there is more risk involved in this procedure than in spraying the nest.
Ground wasp nests
When yellow jackets are found nesting in the ground, first try pouring a soap and water solution into the entrance. Many types of soap will work, including dish and laundry soap. (Do this at night)
If that doesn’t work, apply an insecticide into the nest opening. Be sure you use a product that is registered for use in lawns or soil. After you are sure all the wasps have been exterminated, cover the nest entrance with soil.
Concealed wasp nests
The most challenging nests to control are those that are concealed in voids behind walls or in attics. Often, the only evidence of the nest is wasps flying back and forth through a crack or hole in the home. It may be wise to hire someone experienced to exterminate a wasp nest. Aerosol insecticides usually do not work very well on hidden nests.
Old wasp nests
Old nests are not reused by wasps. Wasp nests found during winter or early spring are old nests from the previous summer. There are no live wasps in the nest; they have already left or died inside it. The nest can be safely removed and disposed of if desired.
Honey bee nests
Honey bees are normally housed in manufactured hives and managed by beekeepers. In some instances wild colonies of honey bees may nest in hollow trees or in wall voids. Honey bees may become a nuisance in the spring at bird feeders and swimming pools as they forage for water. They seldom, if ever, are a nuisance in summer or early fall.
Wild colonies can be treated with the same insecticides and methods as described for exposed or concealed wasp nests. Control of honey bee nests can be challenging. Consider hiring an experienced pest control service if a honey bee job appears too difficult.)
Bumble bee nests
When a bumble bee nest is a nuisance, treat it with the same insecticides and methods as described for ground-nesting or concealed wasp nests.
There are other types of bees you may encounter that do not form colonies. Solitary andrenid bees are common ground-nesting bees. They are also important pollinators of native plants. They usually nest in sun-exposed, dry areas of yards. Although there is just one bee per nest, many of these bees typically nest close to each other. They are usually most conspicuous to the public during spring. Although many ground-nesting bees may be found flying around their nests in the spring, they are gentle and very rarely sting people. Sprinkling the area of their nests with water may be enough to encourage them to move as they avoid damp areas. The same insecticides that control ground-nesting yellowjackets and bumble bees are effective against andrenid bees.
