I want something that keeps mosquitos away and diminishes them. I don't want to kill spiders.
Wondercide Flea & Tick Control Yard & Garden RTU Insecticide is labeled for killing fleas and mosquitoes, and for repelling mosquitoes, ticks and other insects. If this product was sprayed directly onto a spider, it may kill it, otherwise it would likely not have a fatal impact on spiders coming into the treated area once it dried.
