Beetle & spider identification..any help is greatly apprecia

[maryxx]

Hi guys,

as much as I appreciate spiders and beetles outside, I do NOT tolerate them in my house

I tried to identify both bugs (especially if they are dangerous to humans), but failed.
..The beetle looks like a darkling or a blister beetle (especially because of the brown secretion around it in the trap)..what do you think?

The beetle is about 1 inch (I found two in my house this week!) , the spider about 0.5 inch (found only once)
Location is Northern California.
I am really thankful for every help! Since many houses here have a bug problem due to the climate, I would like to prevent a possible infestation immediately!

Thanks a lot!

EDIT:
I got a new houseplant 2 weeks ago and since I never saw these beetles in my house before, I blame it on this plant..not sure if this helps with the identification

The first is a common ground beetle, family Carabidae. The other, well it's a spider is about all I can say. Both are nothing more than casual visitors indoors and not of concern as pests. I wouldn't be concerned as trying to prevent the occassional insect or spider intrusion into a home, except for maybe inspecting items stored outdoors before bringing them indoors, could be a lot of expense and effort for little gain in my opinion.
