Mavrik is going to be most effective as a contact spray and can continue to control certain insect pests for a week or longer though it should be reapplied as needed. Talstar P will have a residual of about 30 days outside. The key with mosquito treatments is to apply to the underside of leaves of trees and bushes as this is where the adults lay during the day.
