Do Scorpions Go in Trees?
Yes, scorpions can and do climb trees. Many species are excellent climbers, especially those that live in deserts and forests. They go into trees to hunt for food, find shade during hot days, and escape floods or predators.
Do scorpions actually climb trees?
Absolutely. Scorpions are natural climbers. Their legs have tiny claws (called tarsi) that let them grip bark, leaves, and even smooth surfaces like glass or painted wood. Some species, like the Arizona bark scorpion, are famous for climbing trees, walls, and ceilings. Others, such as the Florida bark scorpion, live almost entirely in trees and never come to the ground unless forced.
Not all scorpions climb, though. Burrowing species—like the giant desert hairy scorpion—spend most of their lives underground and only rarely venture up a trunk. But if you live in a warm region with trees, you can expect some scorpion species to be up there.
Why do scorpions go into trees?
Scorpions climb for three main reasons: food, temperature, and safety. Trees offer a buffet of insects like moths, beetles, and caterpillars. Scorpions are ambush predators—they wait on a branch or under bark, then grab passing prey with their pincers. Trees also provide shade during scorching afternoons. On hot desert days, the ground can reach 140°F, but a tree trunk might be 20 degrees cooler. Finally, scorpions climb to escape flooding. In monsoon season, tree branches become safe islands above rising water.
During mating season, male scorpions also climb to find females. Some researchers have found that tree-dwelling scorpions communicate by vibrations—tapping their legs on branches to signal their location. So trees can be a busy scorpion highway at night.
What types of scorpions are found in trees?
Not all scorpions are arboreal, but several common ones prefer trees. Here are the most notable:
- Arizona bark scorpion (Centruroides sculpturatus) – Found in the southwestern U.S. and Mexico. Highly venomous, frequently climbs trees, walls, and even into attics. Its slender body and long tail make it a nimble climber.
- Florida bark scorpion (Centruroides gracilis) – Lives in the southeastern U.S., Caribbean, and parts of Central America. Spends most of its life in trees, especially palm trees and oaks. Not as venomous as its Arizona cousin, but still painful.
- Asian forest scorpion (Heterometrus spinifer) – Native to Southeast Asia. Large and black, but not a strong climber; it stays low in bushes and fallen logs rather than high branches. Still, it can scale short trees.
- Bark scorpion (various species) – Many Centruroides species around the world are tree-dwellers. They prefer rough bark where their flat bodies can hide.
For a quick comparison, here's a simple table of two common tree-climbing scorpions and two ground-dwelling species:
| Species | Region | Climbing ability | Danger level |
|---|---|---|---|
| Arizona bark scorpion | Southwest U.S., Mexico | Excellent – climbs trees, walls, ceilings | High – potentially fatal to children and pets |
| Florida bark scorpion | Southeast U.S., Caribbean | Excellent – lives mostly in trees | Moderate – painful sting, rarely deadly |
| Giant desert hairy scorpion | Southwest U.S. | Poor – rarely climbs, prefers burrows | Moderate – mild venom but large size |
| Black emperor scorpion | West Africa | Poor – mostly ground-dwelling | Low – calm temperament, weak venom |
How do scorpions get into trees?
Scorpions climb using their legs and specialized claws. They don't jump or fly—they simply crawl up trunks, along branches, and under loose bark. Some species are so good at climbing that they can scale a smooth metal pole. If a tree has low-hanging branches touching the ground, scorpions walk right up. They also climb walls of houses and then drop onto tree branches. In urban areas, scorpions often use tree branches that touch roofs or fences as bridges to get inside homes.
Scorpions are nocturnal, so they do most of their climbing at night. During the day they hide under bark, in tree hollows, or inside palm fronds. If you shake a palm tree in Arizona during the day, you might see several bark scorpions fall out.
Are scorpions in trees a danger to humans?
Yes, especially if the tree is close to your house, patio, or play area. Scorpions can fall from branches onto people below. Children and pets are at higher risk because they are closer to the ground and may grab at hanging branches. The most dangerous scorpion in the U.S.—the Arizona bark scorpion—is a tree climber. Its sting can cause numbness, vomiting, and trouble breathing, especially in small children. Other tree scorpions, like the Florida bark scorpion, have painful stings but aren't usually life-threatening.
Sometimes scorpions in trees go unnoticed until pruning season. When you cut a branch, they may drop onto you. Always wear gloves and long sleeves when trimming trees in scorpion-prone areas. If you live in the Southwest U.S., consider having a pest control professional inspect your trees before major trimming.
How can you keep scorpions out of trees near your home?
The best approach is to make your trees and home less inviting. Here are practical steps:
- Trim branches away from your roof, walls, and windows. Scorpions use branches as bridges to enter attics and upper floors. Keep at least a 3-foot gap between trees and your house.
- Remove debris from around the base of trees. Fallen leaves, woodpiles, and mulch give scorpions hiding spots near the trunk. Rake them away.
- Install sticky barriers around tree trunks. A band of sticky tape (like Tanglefoot) can trap scorpions trying to climb up. Change it every few weeks.
- Use a black light at night. Scorpions glow bright blue-green under ultraviolet light. Walk around your trees with a black light flashlight to spot and remove them safely.
- Seal entry points on your home. Check for gaps around windows, doors, vents, and utility lines. Use caulk or weatherstripping to close these gaps. Scorpions that climb trees can easily sneak inside through tiny cracks.
- Consider insecticide treatment around the base of trees and along the stem. A professional can apply a residual spray that kills scorpions on contact without harming the tree.
For quick scouting, a black light flashlight is your best tool. It lets you find scorpions after dark before they climb into your home. Another useful item is sticky glue traps that you can place at the base of trees or along fences to catch both scorpions and the insects they eat. For sealing gaps, choose a silicone caulk that works on wood, stone, and siding.
What should you do if you find a scorpion in a tree?
Don't panic. Most scorpions are not aggressive and want to avoid you. Stay calm and follow these steps:
- Identify the scorpion from a safe distance. If it's an Arizona bark scorpion (slender, yellowish, small pincers) treat it as dangerous. If it's a larger, dark scorpion with thick pincers, it's likely less venomous.
- Keep kids and pets away from the tree area until the scorpion is removed or gone.
- Use a long stick or pole to gently knock it into a bucket or jar. Scoop it from below, never from above (they can sting upward).
- If it's near your house, spray it with an insecticide labeled for scorpions, or call a pest control professional. Do not crush it—some scorpions can still sting after being crushed.
- If you are stung, clean the area with soap and water, apply a cold pack, and seek medical help if you have trouble breathing, swelling, or if the victim is a child or elderly person. Call poison control (1-800-222-1222 in the U.S.).
To prevent future visits, inspect the tree every few nights with your black light. Remove any scorpions you find and take away any branches that touch the ground or your home. With consistent checks, you can keep your trees scorpion-free.
