The traps are set in areas mosquitos like. Once set, these will attract the mosquitoes causing them to be infected while laying their eggs in the treated water inside. These mosquito larvae will not become adult mosquitoes, and the female will fly off infecting other sites she lays her eggs.

Female mosquitoes after coming into contact with the treated pad are less likely to bite. They will also die within several days of contact. Her larvae in the trap will not become adult mosquitoes, and the population in the area should continue to decrease!
