What can I do to get rid of a massive spider population infesting my backyard? (about 2/3 acre on a hill)...
For spiders and other pests in a large area in the backyard, Permethrin SFR would be a good choice. It is a liquid concentrate that you mix with water and apply using a hand pump sprayer. It is labeled for just about any insect you could have.
