This is a device to which I wholeheartedly give my seal of approval. It worked when nothing else, including professional help, would. My personal experience with this product is overwhelmingly positive...a unique solution if you need to chase rodents from an enclosed space.
Had two holes a foot wide chewed into my attic and the critters partied every night. Had exterminators come in and offer to plug up the attic for $3200. Searched for an alternative and found Evictor. Figured it was worth a try and bought two 10K strobes to cover the attic. Have not heard a peep since I installed them. Been a year and need to replace the bulbs. Not cheep as bulbs go but I can buy a lot of them for $3200
