Hello,
The spider in that photo is definitely not a Brown Recluse Spider. It lacks the "violin" shaped marking on its back. I'm not sure but the spider you are looking at might be a Woodlouse spider.
Our traps are only guaranteed to catch Brown Recluses, but they will catch other spiders with similar anatomical features. They will also catch crickets, roaches and other undesirable insects.
Thanks,
Tom
