We’re having a ridiculous flea issue. My son and I get bitten by them in bed- my husband and daughter don’t. We run the blankets, pillows and sheets in the dryer every night befor bed, vaccuum the bed, etc, etc. We’re covered with bites. We’ve made homemade light traps and have caught a fair amount this way. We keep the animals out of the bedrooms almost completely at this point. We give them Capstar and Program. And we have diatomateous earth, etc.
