Here is some background info:
- The actual size of these critters is about 1/16"
- We live in Herriman about 30 miles Southwest of SLC at an elevation of 5300 feet.
- Our home is 1.5 years old.
- The insects are primarily found in our first floor gym, which is technically our basement, but since we live on a hillside, our basement is 75% above ground.
- There is an above grade window in the gym that has a planter outside, which is filled with brown dyed decorative bark.
- We do not have any moisture issues in the room, except for minor condensation on the window during the colder winter months.
- The planter gets water twice daily, but the plants have individual drip lines, so the majority of the soil does not get wet and is not moist.
- We maintain our indoor humidity at 35-40%.
- On the dozen or so specimens I have observed, I am unable to identify any visible wing structures.
- Behavior: They prefer the dark as they seem to congregate under items laying on the floor. When exposed, they crawl about very quickly despite their diminutive size. There is no obvious food source in the room, so it is unclear why they have entered the house.
