Hello from the east coast. Just wanted to share an idea. Hubby and I recently were away for several weeks. Before we left I had noticed some ants around a door frame, inside. I sprayed as I thought necessary, ok fine. But on the day we left I set off 2 bug bomb sprayers, locked up and went on our way. Surprised to see a couple of crickets, about 6-7 spiders, several silverfish etc. when we got home. An added bonus. I consider us "bug free" as of today!
