While the cooling temperatures of fall months reduce the activity of wasps and other stinging insects, this is the time of year that wasps are preparing for winter and looking for places to stay warm. This dispersal can create problems for homeowners, where these wandering wasps may migrate into their homes. Controlling the entire nest now helps your customers protect their homes before they become active again in the spring.
Here are some tips to help you and your customers identify and control a stinging-pest infestation:
• Eaves are the most popular nesting spot for most species of paper wasps. Other areas to check include attics, soffits and window and door casings.
• Paper-wasp nests are typically umbrella-shaped and built out of a paper-like material. In addition to the common locations listed above, they can be found on light fixtures, grills, outdoor furniture and mailboxes.
• Hornet nests may resemble a large gray football. They are usually affixed to trees, bushes and the side of the house.
• Yellowjacket nests can be difficult to spot. They are typically built underground, beneath rocks or inside attics and/or crawlspaces indoors.
• Nests may be easiest to spot in the early morning when colonies are most active. However, they are best treated in evening hours when they are less active.
