For the soak I did 2oz of brown listerine to a gallon of water with a Tsp of castile soap and a Tsp of neem oil for two hours. Some of the critters tried to escape the water by moving to the tops of the leaves that were sticking out, these I took out with alcohol and a Q tip.
Hope the little bastards enjoy Davey Jones locker...
Any that survived got another alcohol spay down the following week and so on.
