5.) Set the trap out wherever you’ve seen these pesky buggers. Some good places might be: flower beds, close to a hedge, near the bird bath, etc.
6.) The wasps will fly into the trap to get at the bait, but have trouble finding their way out. They’ll eventually drown in the liquid bait.
Bait ideas by insect category:
Bees are generally not attracted to sour mixtures, but are very attracted to sweet mixtures. For example, honey diluted in water is a great attractant. Other ideas include: Jam dissolved in water, fruit juice, beer, sweet soda, wine, maple syrup diluted with water, and molasses diluted with water.
Wasps and Ants are looking for either protein or sugar depending on the colony needs at the time. Set out two different traps with the two categories of bait or mix the two together (eg. Sugary Juice with a piece of meat). Other ideas: Jam dissolved in water, fruit juice, beer, sweet soda, wine, maple syrup diluted with water, molasses diluted with water, or raw meat such as hamburger meat or tuna.
