Are there any plants that are known to repel spiders indoors?

Answer 1

No, sorry, no spider repelling plants. I'm guessing you have a phobia, or are over run with garden spiders. if it helps, provided you live in the U.S., there are only two spiders you really need to look out for and that is the Black Widow and Brown Recluse (fiddleback). Fortunately, these two spiders are very shy and you pretty much have to find their hiding place even to come into contact with them. All the other spiders are common garden spiders or fly spiders and completely harmless. If they do bite the chances are you won't feel it and it will resemble a mosquito bite. Really all you can do is swat them or catch them and let them go. Spiders are really more of a friend than a foe. Good luck

Answer 2

No. And besides that, spiders are hard to kill. Most exterminators will not treat for spiders-they are afraid of liability. The best thing you can do is to buy an airesol insecticide that is labeled for spiders. Don't spray it all over the home, just wait until you see a spider and then zap him. If you get some insecticide on the spider-it will die within a few minutes.
