Before introducing the Pest Border we spent 12 months studying the behavior of Bark Scorpions and two years of testing exclusionary methods for scorpions before ASU Entomology Research Center began their testing.
Bark Scorpions are tough little creatures some simple facts:
- Exoskeleton (body armor)
- Uses its pincers (claws) to constantly feel, eyesite must be very poor
- Nocturnal (most active at night)
- Go long periods between each feeding for bark scorpions
- Always seeking water
- Don’t dig, jump, or fly
- Gives birth to 30 or more live babies at a time
- Sting can be very uncomfortable or painful, rarely lethal
- Glows green under a blacklight
- Very hard to control with conventional pest control, especially bark scorpions
Bark scorpions are the most venomous scorpions in the USA. As adults they have the ability to control how much venom they disperse to their prey or other life forms (like us or our pets). The young have not learned how to do this yet so when they sting they usually release all they have. That’s why stings from the young are more painful.
If you have the presence of scorpions it is almost impossible to eliminate them completely with the use of pesticides. Scorpions are part of the spider family (arachnids). Their bodies are elevated off of the ground. When walking across pesticide treated areas the only contact they make is with there palps (or little feet). They do not groom themselves like cockroaches do and spread the poison on their bodies – so it has no effect on them. A scorpion has to be sprayed with a direct hit or squeeze through a tight opening that’s been treated and their body is exposed to the pesticide, otherwise a scorpion can walk across pesticide all day and have no effect on them.
Bark Scorpions eat rarely, trying to eliminate their food source with continual pesticide treatments do not eliminate them. They are always seeking water. That is why often you will find them under plant pots, wet towels (don’t let your kids leave their pool towels on the ground), in your home they will often show up in the wet rooms, laundry room, bathrooms, etc.
It only takes one pregnant female to introduce a scorpion problem on your property since they give birth to thirty or more babies. This female scorpion can come from a neighbor’s yard, or new plantings introduced. Yesterday you didn’t have scorpions – today you do.
The best way to be proactive in the battle with these bark scorpions is blacklight hunting, and moisture lures. Many people go out at night during their active hours and hunt them with a black light flashlight, they glow green when shined on. This helps reduce the population, but they’re always more coming.
