Moms is back! I've found that soils that contain added Mycos usually come preinfested with fungus gnats. Since this is their food source. Just add water and they come to life. I don't know if they have it up there but I use a product called "mosquito bits"and cover the surface of my pots with them. They contain a special bacteria which kill them in the grub stage. Around week 4 I usually add a 1 inch layer of 1/8" to 3/16 pumice. The pumice drys fast and they don't like to lay eggs in dry substrate. That with the sticky traps keeps them at bay.
