Help!

[Leafmite]

When I was bringing the plants inside, I discovered that I had infestations of bush snails and pill bugs with some colonies of mealy bugs. I haven't seen any of the three for nearly a month. I spread coffee grounds on the soil of all my plants and added some to the orchid pots as some studies have shown caffeine to be effective on Bush Snails. I also added sluggo plus for the pill bugs and sprayed the plants with Neem Oil three times a week for three weeks. Either the caffeine alone or the combination seems to have worked.

I really hate bush snails. I had gotten rid of them the last time with Sevin but, about a year ago, I found one in an order of new plants and picked it out, then examined all the other mounted plants very closely. Unfortunately, the snail I found must have either left behind hidden friends or eggs. I kept looking for them and would find one now and then after but they really exploded, apparently, over the summer.
