For effective use, traps should be placed outdoors two or more days prior to the event. If applications must be made during the day, the use of protective equipment, such as gloves, hat, bee veil, coveralls, etc., will prevent stings from any foraging wasps. Nests are typically built in animal burrows, cavities formed in thick mulch piles, or other protected cavities such as rotted tree trunks, wall voids, and ceilings. An alternative is injecting an insecticide dust (registered for wasp control) into the entrance. Some yellowjackets nest in the ground and others build papery nests in shrubbery. The yellow-traps and lures which work well for yellowjackets will not work for European paper wasps, hornets or other bees. In addition, this species uses pheromon… It is important to know that no trap provides rapid knockdown of yellowjacket populations.

Unlike honey bees, yellowjackets can sting repeatedly and they will often do so near their nesting site. The more stings, the greater the risk. The only recognizable physical distinction between the two is the body type (paper wasps are much thinner near the waist and is larger than Yellowjackets). That means they work together to build their nests and protect those nests. If you go into an outbuilding or shed, you might find yourself face to face with a lot of angry yellow jackets.

The Eastern yellow jacket (V. maculifrons) is the most common species in these parts. They will even go around obstacles or hover near water and wait. Yellowjacket larvae eat meat and carbohydrate rich foods gathered by the workers. The workers, drones, and old queen die at the onset of cold temperatures, while fertilized, new queens seek protected places to overwinter. Adult workers chew and condition the captured insects or meat to feed to the larvae. Yellowjackets are capable of multiple stings, but only to a limited extent. Queens are visibly larger, approximately ¾-inch long. The larvae within the nests are white and grub-like. Nests are constructed entirely of wood fiber mixed with wasp saliva and are completely enclosed, except for a small opening at the bottom. 37: 73-92.

Yellow jackets are not your normal wasp. Foraging workers will fly into the trap in search of the bait. Goggles are recommended as the workers are known to squirt venom at animal eyes. The queen feeds the young larvae for about 18 to 20 days, which then pupate and emerge as worker-daughters that assume the tasks of the nest: gathering wood fibers to expand the nest size, foraging for food, caring of the queen and developing larvae, and colony defense. Desensitization therapy has proven very helpful to many people with allergies to stings of bees and wasps. Be careful when you picnic. Unlike the European hornets we visited in a previous episode, these gals seem to seek vengeance with little provocation. Abandoned nests typically decompose and disintegrate during the winter or are occasionally reused by another queen. By late summer and early autumn, colonies may contain thousands of workers and are often about the size of a football. Fly swatters, pressurized contact sprays, or aerosols labeled for indoor use can be used. When attacking, yellowjackets release a chemical signal called an alarm pheromone into the air.
