How do get rid of sal bugs?

Any granular pesticide will knock them out. They live under rocks etc. so if you granulate, your sprinklers will add the water and the pesticide will be released slowly over time until it is all dissolved. Just use a hand spreader to put it out like a whirlybird. You can use Deltaguard, Talstar or pretty much any granular to knock them out although it might take a couple applications if you have a lot. A power spray would be better yet but is costly and they are harmless.
