[QUOTE=EdFNJ;1926314]I spray the perimeter every 6 months as suggested by the label on Talstar P. Haven't seen hardly anything in 2+ years. Before that it was a mess. Someone here recommended that stuff and it worked like a charm. Water based and safe for animals and children outside and inside. It's a concentrate mixed 1/2 to 1oz per gallon of water in a pressure sprayer. It seems the one bottle i have should last probably 10 years for around $25.
