Hi
@Fergie1984 the best way to deal with them is with yellow fly traps. you can also apply some product to protect your plant like the bio bizz leaf coat. neem oil is also a good option but I think it delays the development of small plants. these mosquitoes love the moist substrate, you can also put a 1 cm layer of vermiculite on top of the substrate. vermiculite dries faster and does not attract them. good luck 💪🙏👍
