Carolyn from Tullahoma, Tn writes,

How effective is borid (ORTHOBORIC ACID 99.0%) in treating for brown recluse spiders?


Cb Borid Boric Acid dust is not labeled for spider control at all. This is because boric acid must be ingested to be effective and spiders cannot ingest the product because of their sucking piercing mouth parts that only allow them to ingest sucked up liquids. Please see our Spider Control Kit for the best products for a spider infestation.
