Eric from Washington State writes,
Can I dilute Evergreen Pyrethrum then water directly to the soil to potted plants for fungus gnats?
Evergreen Pyrethrum is labeled for fungus gnats but it does not state on the label that it can be applied for long term control on potted plants. We do carry Bonide Systemic Insecticide Granules that is labeled for treating fungus gnats in potted plants. Please refer to the product label for specific application instructions.
