Azatrol is a neem oil extract. Its a systemic, so it's going to take a while for it to work. You can try multiple modes of action to ensure eradication. Easier said than done.. I recommend you clean your grow area, including filters and fans. Use best business practices. Wash your hands before and after working with them, if you have outdoor pets, keep them out, etc.
Do you know how you got them? Is it a clone?
