The insect in order Hymenoptera are considered important part of ecosystem because they help in pollination and are parasite to other pests. But they pose a threat for human beings and other animals when they start dwelling localities and areas used for recreational purposes. They scavenge meat and other sugary substances making them nuisance near trash receptacles, garbage cans and dumpsters.

s.

• Make the buildings porous free. Caulking and sealing of openings should be done in attics, window frames and around walls for exclusion of habitats for these pests.
• Dumpsters and Garbage cans should be regularly cleaned and they must be fitted with tight lids.
• Food scraps when thrown out should be securely closed in garbage cans because their smell is open invitation for these pests.
• Attractants to the bees and wasps that include meat and other food should be kept under control.
• Draw off out any stagnant water that has accumulated in and around your building.
• Despite of all these preventions, if the problem is not solved, then prefer organic ways rather than chemicals. Horticulture oils can be used in this regard because this is repellent for insects.
• Kerosene oil smell couldn’t be tolerated by most insects. If sprayed even in fewer quantities near the hives, the bees will fly away. If sprayed on the hives (with proper preventative measure), plenty of bees will either die at once or some time later.
• Sprinkle food-grade diatomaceous earth in the area. This is a more potent pesticide that will also affect pests in the hive.
• Insecticidal dust is useful around and on the hives; bees and wasps that come in contact with it will die. One such dust is Delta Dust.
• If still more toxic pesticide becomes necessary, apply a pyrethrin
• Remove old nests and scrape the point of attachment.
• Application of pesticide should be done at night, because at this time all the workers are present in colony and are less in activity. Wear Bee suit to secure yourself from their aggressive attack when doing this.
