Speaking of spiders.....
When we moved into this house we had all kinds of spiders inside of it. It had been vacant for three months. I mean, big spiders, little spiders, spiders I had never seen before. They showed up everywhere! In dresser drawers, in the kitchen cabinet. We bombed the house only to have the spiders back in a few weeks. SO we went to our county extension agent and he told us to use an insecticide on our lawn as the spiders were probably living in there. We didn't have any pine mulch around the house. We put on this insecticide (you only used a very small amount, water it in and it foams up and the foam then penetrates the ground) and within an hour all of our sidewalks and the driveway were literally covered with spiders! It looked like something out of a Stephen King novel. I used the garden hose to wash them all away. But almost instantly, we didn't have any more spiders in the house since. We have a St. Augustine lawn and live in a country environment. I guess they were happy in there, the spiders that is.
