When I do this, I usually see some surprised, scared pill bugs wondering where their home went. What I\u2019m aiming to do is give them no shelter close to my baby vegetable plants, which reduces their feeding on them. All animals are as lazy as we are and will eat as close to home as possible.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">I sometimes add some compost to the surface of the soil at this time.
