when you have an insect infection, there is only one safe solution that works 100% of the time. Throw out your plants and clean every piece of equipment with bleach and soapy water. Wash your walls, your lights, your floor, or pots ect. Get rid of ALL plants, and start from seeds. Neem oil will only stop them temporarily, the infection of insects is in the room you are growing in and not just on your plants, so act accordingly.
