I spent about 2 days in the high desert. I didn’t see any snakes like I wanted to but I got some good documentation of Loxosceles habitat, including in the house I was staying at and next to my bed.
Microhabitat:
The spiders really love decaying wood. I found none under rocks. They also shared habitat with some sort of rodent I couldn’t identify.
Gravid females and eggs
I found several gravid females, and a couple on eggs. I also found 2 pairs living together. The mothers would attach their egg sacs to the top of the wood they hide under, often weaving it into a natural crevice. Their egg sacs are very flat and are covered by a fairly thin layer of silk.
A mom with a very pretty coloration. She has only 5 legs also.
A pair that I found living under a piece of wood.

Indoors
The house that I was staying at was very likely sprayed with pesticides but I have no solid evidence to support this.
The way I discovered the ones indoors was when I decided to get water at around 10PM. I looked and saw several Loxosceles running around on the floor, mostly mature males. After this I grabbed a flashlight and looked around in crevices and behind furniture. Again, the spiders readily occupied anything made of wood. I uncovered a mature pair behind a small bookcase and several more in similar areas. All the areas I found them had evidence of them living there for a long time as evident by multiple molts.
In total I collected about 7 indoors. I released all but one mature male. I saw several others that I was unable to capture as well.
Juvenile I found under my nightstand
