Don't worry, they're just eating booklice (another common name for pseudoscorpions is book scorpions) or carpet beetle larvae or flies or clothes moth caterpillars. So they're helping you out. Here's another mama carrying her eggs.

A macro photo, lateral view, of a mother pseudoscorpion carrying her large eggs underneath her curved abdomen. She is orange-brown, and the shiny yellow eggs are large relative to her size (only two are visible, and she could probably only manage 4-6). She walking across a pale orange-tan rock.

Mama pseudoscorpion & her cute baby high in the mountains of Montana. Mama is half the size of a grain of rice. These harmless micro arachnids have no stinger, but can deliver venom to prey via their pincers. Also, they can walk backward. Also, you probably have them in your house. #BugSky 🐙🌿

A macro photo looking down at a mother pseudoscorpion and her baby. They're on a patch of pebbly, sandy substrate. These arachnids look kind of like regular scorpions but without a tail and stinger, which means they are to regular scorpions what corgis are to collies. The mama is dark orange with reddish-orange pincers, while the tiny baby facing her is translucent, with a bluish white cephalothorax and pale yellow abdomen.

A very pale but very gorgeous female Dicranopalpus Harvestman sat on the side of a tree at the Cotswold Sculpture park Gloucestershire. Just to the right of it was this very simple sculpture of an owl having a tussle with an earth worm. #Harvestmen

Built by the spiders. Actually watched one making adjustments to it's retreat. Visited Rhoose Point, only a short distance from Porthkerry, with R.Gallon today and the igloos were abundant at this site also. Will hopefully get an ID on the specimens collected

The grass/stone bank line produced lots of spider igloos under the stones near areas with ant activity Zodarion fuscum. Most igloos had egg sacks, some were being used by imm. salticus. Recorded here previously, the third different location I have come across it locally. @britishspiders.bsky.social

A pale specimen like this is almost certainly Larinioides cornutus and although the other two Larinioides sp. have been recorded in Scotland, they are not common. Not able to reply to your original post so quoting instead.

Spider prey item in Tree Sparrow's bill. AI suggests Larinioides cornutus, but Britian's Spiders, a field guide, says difficult to take to species. So do I record as Larinioides sp? @britishspiders.bsky.social - hope you can help. At @rspbscotland.bsky.social Loch Leven reserve.

Popped the Steatoda triangulosa female into a container for temporary storage. When I checked 2 hrs later it had constructed an egg sac, attached to the underside of the “lid” (a piece of curtain material). It had looked quite gravid when I found it, but I didn’t realize it would lay so soon.
