Jeff from Beckley, Wv writes,
Is it safe to apply Precor IGR to mattresses and box springs for flea control?
You do not need to actually spray the mattress and boxspring with Precor for it to effect fleas that may be hidden there. If you spray around the area where the bed is located the fleas will still be effected because of the unique molecules of this product. You should also thoroughly vacuum the bed to remove as many fleas eggs and larva as possible.
