It's located above the rear differential. According to the dealer, the evap system draws in air on the passenger side near the front door via a tube/ductwork integrated into the unibody.
Other than using spider spray near the point of entry, the Subaru field tech said they can't place a screen or something similar to prevent spiders from entering due to the design.
I don't think the dealer will keep cleaning spiders out for free if this happens again. Hopefully it won't. Not sure why there's an overabundance of these yellow sac spiders this year. We did have an unusually dry summer up until last month though.
I wouldn't consider it preventive maintance under most conditions. I'll certainly be keeping an eye on it though. If you get a CEL related to emissions and the dealer can't quite find out why, this may be it.
