You can go to Wal mart and there is a product in garden area ( SAFE GRO ) it is used for Tomatoes it has Pyrethins in it Look for that PYRETHRINS. Or you can use NEEM OIL and a shot of dish soap and spray up and down heavy, either way they will be back in 4-5 days you need to spray again 3 more times being the eggs will hatch and all over again. I say use the Pyrthins then wait 7 days and got o the local nursery and buy either lady bugs 1500 for 7$ or Praying mantis. I just set off the lady bugs 2 days ago and the S.M. have not returned, they eat the eggs and adults all gone.
