If you’ve ever spotted a tiny, scorpion-looking creature in your home around the holidays, don’t panic — it might be a pseudoscorpion, and it may have arrived on your Christmas tree.
Pseudoscorpions are very small arachnids, typically only a few millimeters long. They resemble true scorpions at first glance but lack a tail or stinger. Instead, they have small pincers (called pedipalps) that they use to capture tiny prey like mites, booklice, and other nuisance insects.
How Do Pseudoscorpions End Up on Christmas Trees?
Live Christmas trees come from outdoor environments where pseudoscorpions naturally live — under bark, in leaf litter, and in forest debris. When a tree is cut and brought indoors, these tiny beneficial predators can occasionally hitch a ride inside along with other harmless outdoor arthropods.
Because pseudoscorpions are cold-tolerant and slow-moving, they may not become noticeable until the tree has been indoors for several days and temperatures warm up.
Are Pseudoscorpions Dangerous?
No. Pseudoscorpions are harmless to people, pets, and structures. They do not bite, sting, infest homes, or reproduce indoors. In fact, they’re considered beneficial, as they feed on other tiny pests.
If you find one, the best solution is simple:
-
Gently capture it with a tissue or cup
-
Release it outdoors
Can Pest Control Prevent This?
This is a good example of why not all insects found indoors indicate a pest problem. Pseudoscorpions don’t require treatment, and pesticide use isn’t recommended or necessary. A quick inspection of a live tree before bringing it inside — shaking it outdoors or letting it acclimate in a garage — can reduce the chances of bringing in harmless hitchhikers.
Final Thought
Finding a pseudoscorpion around the holidays can be surprising, but it’s ultimately a reminder that live Christmas trees come from real ecosystems. In this case, the visitor is temporary, beneficial, and nothing to worry about — just another tiny part of nature tagging along for the season.
