Yes, The Wasp-X Wasp & Hornet Spray wil spray upside down. Upside down spraying allows for hard to reach nests.
There is not a specific expiration date on Wasp-X Wasp and Hornet Spray, but we would recommend using within about 3 years of purchase. You should store this product out of extreme temperatures to ensure it stays stable on the shelf, and be sure you shake well before using. Since this product has a foaming action, you will apply in 1 second bursts, rather than holding down the nozzle for several seconds.
Wasp-X Wasp & Hornet Spray is sprayed directly on the nest. It will foam around the nest so you do not need to make holes. The foaming action provides a residual activity to help eliminate the nest. Wasp-X spray can reach nests up to 20 feet away. The water-based formulation is easy on plants and the active ingredient is safer for the environment yet tough on pests.
It is recommended to avoid spraying plants or foliage when using Wasp-X Wasp & Hornet Spray.
If you are able to locate the holes and/or nests, Wasp-X Wasp & Hornet Spray is a great product to use. It kills very quickly and has a long distance spray so that you can treat the nests from a safe distance. It's best to spray the nests at night, when they have retreated to their nest for the night and are no longer active. Once you've treated the nests directly, you can spray surfaces so when bees land on the surface they will pick up the spray and die. A product like Demand CS can be sprayed around the perimeter foundation of your home, around doors and windows, in the lawn and ornamental landscapes, etc.
Cricket Hunter Wasps can be found indoors year-round and will often occupy existing holes in the ground or in cavities in the walls of buildings. Inspection and exclusion will be important for keeping this pest out. Wasp-X would be good for knockdown outdoors and for hard-to-reach areas. Insecticide dust such as Tempo 1% Dust applied with a B&G Bulb Duster 1150 would be great for cracks and crevices and void treatments.
Also, since these wasps target crickets, you may want to use a cricket bait around the structure, such as InTice 10 Perimeter Bait.
