How long will each application of ULD BP-100 Fogging Concentrate be effective?

Most professional Mosquito Fogging services say their treatments will last 21 days. Black Flag claims their treatment will last about 6 hrs. How long will ULD BP-100 last?


Like most fogging concentrates on the market the ULD BP-100 is a contact kill insecticide and will not leave behind a residual to give a continuous kill. Fogging is mostly designed for the instant control and knock down of pests in the area and to kind of keep them away for a few hours. For continuous control you normally use products that are not applied with a fogger and that have a residual to give you control over several weeks as the mosquitoes land on the treated surfaces. We would suggest taking a look at our Mosquito Control Guide and clicking through the steps for treating and prevention and through the kits we offer to help get the best results.
