Riptide is a contact kill; it does not have any type of residual effect after it is dry. Talstar P (Talstar One) has a residual effect that would keep on killing for at least 30 days outdoors and 90 days indoors. They are both wonderful options for mosquito control but if you are looking for something that is going to last longer, we would recommend using Talstar P (Talstar One).
