Yes, me too!

A lot of pill bugs and millipedes. I know the millipedes just munch on rotting stuff so that wasn't a problem for me. The only trouble I've had with pill bugs, or rolly-pollies, is that they will occasionally take up residence in one of my potted plants that sits on the ground. I don't see a lot of damage to the roots, however, they are just liking a nice protected home.

I think pill bugs (which interestingly enough are not bugs-they're crustaceans) can and will eat plants on occasion but in general prefer to eat rotting stuff like milipedes. Now, say you have some tomatoes that got left on the vine too long, especially ones that are growing on the ground - or got damaged in some way I think that would be an open invitation to a host of creepy crawlies, pill bugs included.

IMO what is more likely to happen is that something else comes along, causes damage to the plant and roly polys come in for a meal or dead or dying plants later.

I have tons of these guys in my garden and anyone who uses mulch I garuntee does too. But, they have never caused any obvious damage, or at least none that I have attributed to them, and I tend to count them as beneficial detrivores like worms and millipedes. Just my $0.02 and Im sure that plenty of people will disagree and they may be right, Im certainly no expert.
