The first step in wasp or bee control is to correctly identify the insect and locate its nesting site.
Wasps have a slender shiny body with a narrow waist and slender, cylindrical legs. Yellowjackets, hornets, and paper wasps are the most common types of wasps encountered by people.
Bees are robust-bodied and very hairy compared with wasps. Their legs are flattened for collecting/transporting pollen.
The best time of the year to control wasps is after the queen has established her colony yet the colony is still small. The best time of the day to control wasp nests is at night, when they are less active.
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 "wasp and hornet spray" into the entrance of the nest during late evening according to directions. To avoid pesticide falling down on yourself, do not stand under the nest spraying upwards. Plan your escape route in case they respond, and be careful if you must climb a ladder to do so. If live wasps are still observed the next day, repeat the treatment.
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.
If wasps or hornets are nesting in the ground, try pouring soap and water into the entrance, including dish and laundry soap, in the evening. If this does not work, apply an insecticide into the nest opening. Be sure you use a product that is registered for use in lawns or soil.
The most challenging nests to control are those that are concealed in voids behind walls or in attics where the only evidence of a nest are wasps flying back and forth through a crack or hole in the home. It is highly recommended to hire someone experienced to exterminate such a wasp nest as insecticides usually do not work very well on hidden nests.
During late summer and fall, wasps and hornets become scavengers and frequently disrupt activities where food or drink is served. Control of scavenging insects is difficult as no insecticides effectively repel or discourage them.
The best strategy is to minimize attracting them. Wait to serve food and drink until people are ready to eat. Promptly put away food when done and throw garbage into a container with a tightly fitting lid. Examine glasses, cans, and other containers before drinking from them to check for wasps that may have flown inside.
VERY IMPORTANT - should a wasp fly to your food or arm, wait for it to fly away or gently brush it away. If you crush them they will give off an alarm scent that will attract others wasps.
Many people make the mistake of placing wasp traps in areas of human activity. Place the traps in a wide circle 15m away from the area you want to be wasp free, sweet smelling liquids are the best attractant. By placing your traps early in the season you will have more of an impact reducing the population.
Wasps prey on many insects, including caterpillars, flies, crickets, and other pests however during late summer and fall they are more interested in collecting sweets and carbohydrates. Bees feed only on nectar and pollen from flowers, but will go to a trash can for a drink can to feed on the sugar.
Wasps and bees have colonies that last for only one year. The colony dies in the fall with only the newly produced queens surviving the winter. The new queens leave their nests during late summer and mate with males. The queens then seek out overwintering sites, such as under loose bark, in rotted logs, under siding or tile, and in other small crevices and spaces, where they become dormant. These queens become active the following spring when temperatures warm. They search for favorable nesting sites to construct new nests. They do not reuse old nests.
