I used Spiderex at home a couple of weeks ago in anticipation of September (Spider month). I am one of these people that has a phobia- I cannot help it. Evryone kept telling me I had to learn to live with spiders but I can honestly say, at a time of year when you normally see a big spider every other day, I have not seen one at home. I have sprayed windows, doors, and all corners, crevices etc. I hope it lasts! I have told everyone how good this product is, as I have seen it for myself. Thank you!
