How do you get rid of toads eating my caterpillars?

Depending on the type of caterpillar, you may not want to get rid of it. It could be a butterfly caterpillar. If it is definitely a pest caterpillar, they sell a something you can put on your plants, bacilus thuringesis (I could be way off on the spelling, but it is often abbbreviated BT) that will kill them, or if you have any wasps or birds around, they may take care of it for you. Unfortunately, I have the opposite problem, the wasps in my yard are eating every caterpillar in sight, unfortunately that includes my monarch and gulf frittilary caterpillars. I am having to rear the monarchs in containers so they don't get wiped out completely.
