Slugs and bugs

My bunnies were away for 3 weeks for holiday boarding and have been back a week. With them being the way and the weather the way it is (warm and rainy) their hutch and runs have lots of slugs and woodlice and other bugs around. There have always been slugs around but there seem to be lots more and there are woodlice living all over the run especially where the tarp sits. Apart from totally grossing me out, is there any damage to the bunnies or their housing from these bugs? I wish I knew how to get rid of them for good

Woodlice live on rotting wood, so check the integrity of your wooden areas: they might be wet-rotting. Shouldn't be a problem to the rabbits and slugs and woodlice shouldn't damage things that aren't already (by water usually).
