You have to discover where they are coming from. Do you have leaves on the floor that are spoiling? Is the room outside the tent dirty? Unfortunately, strains like strawberry cough do attract more pests. If your environment is clean, all you can really do is continue treating with neem oil and trapping. I also recommend looking into bud washing once you harvest. Seems counterintuitive, but it will make sure you're not smoking bugs and fecal matter. Trichomes dont dissolve in water, so it shouldnt hurt your final product. The 3 bucket method for bud washing is best. Good luck friend!
