Death by Coffee

Had a snail invasion like I've never seen before.  As fields are drying out, snails are looking for moist areas.  Home gardens which get watered as needed are ideal. Just walking around the yard I frequently hear the crunch under my feet of crushed snails.

They are vegetarians and ate a crop of one inch green bean plants overnight. Also ate through fresh cactus

 

Coffee grounds are recommended on the net.  I tried instant coffee and caused instant death.  If coffee is watered down destruction is not so instant. Snails seem to cluster together.  I moved this group near the banana trees.  Coffee contains acid banana plants prefer acidic soil
