What products are y'all using for fleas in the yard? As of right now we've been using Tempo SC Ultra in a fogger for fleas along with bifen granules in the yard. The owners want me to sell this as a one time service for $225 and it's not working for 80 percent of customers. What are y'alls recomendations? I've thought about a flea, tick and mosquito program every 21 days. What's worked for y'all? I'm in Jacksonville FL for reference.
