On today’s visit, I treated a yellow jackets nest in front of house and removed paper wasp nests by garage. After about 2 to 3 days, the wasps should become lethargic, 5 to 7 days activity should die down significantly, and 10 to 14 days, the nest should be neutralized. If there is activity after 10 to 14 days, please call us back for a re treat. Thank you for choosing Green Pest Solutions!
