Glad to hear that things are working well! I have had a few customers who want to have you re-spray every two weeks, not sure if they just think because its free they need to do it or if they have unrealistic expectations, or maybe just want my body lol. When I spray the same neighborhoods six times a year and only have one person who calls every month about a re-spray I tell them that we cant continue to provide free re-sprays every month & that they need to move to my advanced 21 day program. If they call back to back, or more than twice in a year I then offer to treat the yard every 21 days instead of every 28, & explain to the customer they have higher than normal pest pressure that exceeds that of there neighbors & we cannot treat for the same price. So far most have managed to be content with the 28 day spraying. I'm glad to stand behind my product & understand that occasionally the customer may need a respray, but when its an every month thing something has to change. Its been a great year for mosquitoes so far!
