[QUOTE="marimus, post: 694268, member: 3924"] You are supposed to cut those tags off a certain number of days after applying them. I'm not sure how many days for the blue ones. Then next fly season you use one of the other colour tags instead. This way, the flies are not exposed to sublethal (low) doses, and can't build immunity to the chemical. By switching to another colour tag, they use a different chemical - so even if some of the flies have developed resistance, they will be killed off by the next colour tag. [/QUOTE]
