Any tips on getting rid of houseplant pests? I tend to bring mine out in the warm months, and use homegrown compost to enrich the soil. Consequently I get fungus gnat issues every stinking year! Their larvae are killing some of my herb pots. Letting the soil dry out between waterings doesn't work for me, and also doesn't strike me as the sagest advice. If anyone has had success getting rid of them, please help!
