The best time of the year to control wasps is in June after the queen has established her colony and while the colony is still small. However, because nests are small, they are also harder to find. The best time of the day to control wasp nests is at night when they are less active.

• Wasps have a slender body with a narrow waist and slender, cylindrical legs.
• The body appears smoothed-skinned and shiny.
• Yellow jackets, boldfaced hornets, and paper wasps are the most common types of wasps encountered by people.
