I am new to this site and would like to inquire if any of you professionals also provide Mosquito control? (i.e. barrier spraying) I have looked at a few franchise offerings in this niche market, but thinking about starting up my own business, due to the high dollar investment for a franchise. I have been doing my reseach as to what license and certifications are required at the state level here in Michigan, so I am good there. Looking more for advice on what would be the best and safest chemical products to apply with a back pack sprayer. Any and all suggestions will be appreciated grately.
