I think it brings the desired result immediately regarding the control of the mosquito population. It may be lacking in duration of action, but the purchase cost allows for several repetitions.

Quite effective for both mosquitoes and other insects like flies, cockroaches, or ants. It made the areas around the house completely human-friendly. Before I sprayed, if I went out to the yard or the balcony, within a minute I would have gotten five mosquito bites. Now they have almost completely been eliminated.
