(Video) is this a common house spider?

[malaise]

My mom thinks it's a brown widow but I didn't think so. I can't get a good look at the underside of its abdomen. It was in our bathroom, I live in the states in Texas and I assumed this is an american house spider just chilling in a corner. I put it in a little enclosure. I had a look at my local spiders and I couldn't find any that had an exact match but it's possible I just didn't search enough.

If it’s not red underneath then it’s something like a Parasteatoda tepidariorum type of spider .

I’d say yes , but I’ll wait for the experts to chime in..

I'm pretty certain it's a steatoda triangulosa (triangulate cobweb spider), great picture for identification.

Yes, this is S. triangulosa:

Are they nationwide or just in Texas?

I’ve swore I’ve seen them here in Ohio, but just curious lol huge amounts of them!!! I had no idea they were communal.

They're not, really. When mine started laying egg sacs, I started reading research papers to prepare, and one paper described the behavior of S. triangulosa slings under different conditions with controls for temperature, humidity, and prey availability. I learned that captive slings don't cannibalize each other nearly as much when they have access to adequate moisture and food, and I think my experiment of sorts verified those findings.

Yep, pretty common house spider

Yeah but it’s not hard to make flies I can make thousands with my roach colony easily . They are invaders but house spiders are killing them off.I’ve never grown a culture though.im trying to kill off the flies. But I got no traps.

 

[darkness975]

They're relatives of Latrodectus. Some of mine are even more food motivated than the widows.

She laid eggs!!! It's a girl! I'm highly excited by this, although admittedly completely unsure what to do with them. I might allow her back to the spot where I found her so she can tend to her little ones.

Got a fly problem? You got the solution. nice ! Baby’s. I don’t know why I never see these in the basement.

 

[NMTs]

Just leave her in the enclosure - now that she's made a sac, you don't want to move her. Once the babies hatch, you can take the entire container outside and take the top off and they'll disperse. Until then, you might stretch a stocking over the enclosure so the babies don't make their way out the air holes.

Thank you for the advice, I will avoid disturbing her and make sure the babs get out safe<3

 

[Contingence]

The problem with that tactic is that she will, 1000%, lay more egg sacs before those eggs hatch. I just went through this lol

I don’t mind spiders in the house. Some have been allowed to make their webs in designated areas.

but the yellow sac spider, is way to at home in my bathroom. At one time, their were hundreds of spiderlings dropping on me while i bathed.

There were so many at one time, i considered getting ichneumon colonies.

i take everything outside. Except jumpers. Those have free reign. I discriminate with class.

Very similar thing happened to me; I was renting from a slumlord and the windows didn't close properly; some Cheiracanthium chose our windows to set up nurseries, and when the slings dispersed we had these chandelier-like structures of interconnected slings and webs all throughout the apartment. They would line up on the ceiling to jump off this little outcropping and then use the fan to balloon across the room. It was wild. In fact, [[ this ]] may be the exact specimen responsible (my first submission to bugguide)

People don’t get that i am not afraid of Tarantulas. And yet, an invasion of sac spiders…
