F.A.Q.

It can, because landscaping decisions affect how much standing water collects, how much shade your yard holds, and how freely air moves through it. All three directly influence mosquito populations.

Yes, barrier treatment works on a wooded property, but there are limits to what’s possible. You can treat your yard and the tree line around it, but not the whole forest.

There's no clear answer. Lake country has more woodland and floodwater mosquitoes because of wetlands and marshes, but cities have more mosquitoes that can breed in small containers like gutters, storm drains, and discarded containers.

Once a barrier treatment has dried and bonded to the foliage, normal rain doesn't wash it away, so your treatment stays effective through typical showers. Rain mainly matters if it falls heavily before the treatment has dried, which is why applications are timed around the weather in the first place. 

Yes, covered docks are common spots for paper wasps to build their umbrella-shaped combs. They like doing this because docks provide lots of protected overhead surfaces where they can easily build such as eaves and boat lift canopies.
