Immediate knockdown/death?
Per the product label, Southern Ag Natural Pyrethrin Concentrate can be used as a space spray for wasps. You will use 1 oz per 1000 cubic feet of space. It needs to be sprayed upwards. The area also needs to be closed off for at least 10 minutes. You will ventilate and sweep up and destroy dead and fallen insects before reoccupying the room. Please let us know if you have any additional questions.
