Answer: Pill bugs and earwigs are usually attracted to decaying organic matter in an area that is constantly damp and moist. They do not usually harm plants, and are a natural part of the decay process. However, if they are appearing in excess, you may want to take steps to discourage them. Eliminate any piles of mulch or gravel, check your drainage and watering patterns to make sure that the yard is draining correctly, and follow correct watering practices: water deeply and less often, avoid a daily light sprinkling.
There are several different kinds of Lobelia. Lobelia cardinalis is a perennial with red flowers in summer that requires evenly moist soil to do well; it will grow in full sun or partial shade. The little annual lobelias with blue flowers do well in morning-only sun (full sun in a cool summer region) and a well drained soil. In general the annual lobelias do not perform well in hot, humid weather.
I hope this helps.
