Wasps are beneficial insects because they prey on many other insects, including crickets caterpillars, flies, and other pests. But during late summer and fall they are more interested in collecting sweets and other carbohydrates. That’s why it’s not uncommon at this time of year for our outdoor activity to be disrupted by their annoying presence!
Wasps come in many types and sizes. The ones that are of most concern to people because of their stinging habits are yellowjackets and hornets. Control of scavenging wasps is difficult, as there are no insecticides that 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. If a wasp flies to your food, 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. This of course attracts more wasps. Place the traps in a wide circle 40 or 50 feet away from the area you want to be wasp free. Sweet smelling liquids like carbonated pop are the best attractant.
