Is this a Recluse?

Asked November 20, 2018, 9:40 PM EST

Found this in my bedroom this evening after getting home from work. It appears, to me, to be a Brown Recluse, but I have a friend in pest control who says no. I cannot find another spider that looks like this in the Missouri Conservation site.

There are many more spiders in Missouri than the Mo Dept of Conservation can put on their website. Here is a bit more information on Missouri Spiders, https://extension2.missouri.edu/g7386. this guide has more pictures and discussion on controls.

Yes, the general appearance is similar to the brown recluse. Getting a good identification of the spider requires a description of eye arrangement and mouth parts. The legs look a little too robust for brown recluse. But, there appears to be a fiddle marking on the back that seems to indicate that it may be a brown recluse. See, https://extension2.missouri.edu/G7386?p=3#Brown. Seldom do we see the brown recluse out in the open.

So, I am undecided. If you still have the spider, you may take it to the St Charles County office for a better ID. Justin Keay is our new Horticulture Specialist in that office and he can help you take a closer look.
