Wasps deliver a poisonous venom in their sting that causes red, itchy, painful welts and a serious allergic reaction in some people. You can differentiate a wasp from a bee by its slender, smooth body. Their papery nests can be found near roofs and windows. Take careful precautions when killing a wasp because wasps are naturally defensive insects that sting when threatened.
Isolating the Wasp
A wasp is difficult to kill when it flies from room to room. Locate the wasp and close all doors and windows in that room. Take children and animals out of the room in case the wasp retaliates and stings a bystander. Turn on all lights to get a full visual perspective; however, high ceiling lights will only draw the wasp up to an unreachable location because they are attracted to lights. It's rare to see a wasp flying inside a home at night because wasps aren't nocturnal insects and typically fly back to their nest at dusk. Use a ladder if you have high ceilings, but have someone hold the ladder steady. To attract a wasp from the ceiling of a room, set out food and sugary drinks or turn on table lamp lights. Wear a thick coat and pants to minimize the wasp's ability to sting you through your clothes.
Grab a can of wasp-killing spray, such as Raid Wasp and Hornet Killer or EcoExempt Jet Wasp and Hornet Killer. Use a can of aerosol spray if you don't have a bug killer in your home. Pick a time to target the wasp when it is away from kitchen counters and open food. Instead of killing a wasp in a kitchen, it is best to wait for the wasp to go into another room of your house to prevent contaminating your food preparation areas. Wait for the wasp to come into spraying distance. Refrain from spraying a cloud of insecticide in the direction of the wasp. Hold out your hand and spray. When coming into contact with the spray, the wasp should immediately fall to the ground. Spray the wasp again once it has fallen. Pick up the wasp with a towel and throw it in an outside trash can. Avoid using tissue paper; if the wasp is still alive, it will attack and can do so easily through tissue paper. Use soap and water to clean all surfaces that may have been sprayed.
Killing a Wasp Without Spray
If you don't have an aerosol spray or don't want to breathe toxic fumes, you can kill a wasp by using other methods. Throw a towel over the wasp and step on it. Stomp on the towel thoroughly, and then pick up the entire towel with gloves to take it and the wasp outside. You also can use a flyswatter as long as you get a good shot. For a wasp flying near a ceiling, use a broom to smash the wasp against the ceiling or a nearby wall. Always be extremely careful because wasps are aggressive insects that will attack when you try to kill them.
