Looks like aphis in the pictures? Generally speaking you can get rid of most bugs with diatomaceous earth or neem oil with a few drops of dish soap. You can also use rubbing alcohol, cinnamon, peroxide, guano foliar feeding, and many more that wont harm your plants if used correctly. Diatomaceous earth is both my favorite and least favorite, it's an all natural micro abrasive in a powder form. Dust the plants as heavy as youd like and never hurt them, but beware, a gust of wind will send it airborne and can irritate lungs and eyes! Its somewhat slow acting at 7-10 days before results, but it works, it's cheap, and it's easy, throw powder at your plants. Welcome to the forum!
