Hi, so I fight them in two ways. One is with yellow sticky boards. The adult mosquitoes stick to them. It also helps against fungus gnats. The other thing I always do is buy nematodes, which are also available on Amazon. You add them to the soil with water, and they eat the mosquito eggs and larvae. It works very well. The exact species used for fungus gnats is called Steinernema feltiae. No more problems. You can also order the adhesives on Amazon. You can also see them in my diaries.
