What lasts longer outside - Barricor SP or Bifen IT? Would one product be safer than the other? I've been using Alpine WSG, but it isn't doing as well on spiders. Would one of these products work better for spiders?
Both Bifen IT & Barricor SP have the same residual outdoors, which is 30 days. For spider control, Barricor would be best. Both are going to just as safe as long as used as directed.
