You can either lay them out flat or fold them up to protect pets and small children from getting stuck. To use the traps most effectively for brown recluse spiders, place traps in closets or other secluded areas where you have seen spiders and/or webs. Rather than exposing yourself and your family to poison (sprays & pesticides), place non- poisonous and natural-attractant-baited Big H TrapsTM to trap Hobo & Brown Recluse Spiders when they move into your homes to keep you feeling safe.
