Bark Scorpions

ProBest Pest Management

Arizona

• Well if you live here you know all about Bark Scorpions – right!– Only scorpion capable of crawling up stucco or

vertical surfaces and gaining access into your home.

– Scorpions have hairs on their legs and bodies that are very sensitive to air movements.

– Scorpions are generally predators eating crickets, spiders and other insects.

Arizona

• They love to hide in cool and moist areas and can be found in any crack and crevice, under rocks and behind stucco and brick.

• They generally are 2 to 3 inches long and can live up to 2 to 6 years.

• Scorpions give birth to live young during the summer months and are often seen riding their mothers back.

Arizona

• The injected venom is a neurotoxin – and can cause respiratory paralysis and other complications.

• New construction often triggers new activity in neighborhoods as they be moved into other areas.

• All scorpions fluoresce under uv light.

Control

• 5-step process– Identify the scorpion– Harborage elimination– Reduce the food supply– Seal the structure– It may be necessary to apply pesticides

Control

• Identify the scorpion– 80 species in the U.S at least 45 of those species in

Arizona – Desert Hairy Scorpion is often much larger than the Bark Scorpion.

Control

• Eliminate the place they hide– The one area we find the most scorpions is the

block walls – it holds the heat well into the night.– Don’t stack firewood near the home, if you have

firewood stack it on blocks and away from the house. Landscape timbers also are great hiding areas.

– Clutter around the home is also a great hiding place for many critters.

Control

• Reduce the food– Scorpions eat crickets, cockroaches and small

insects so by removing them from the equation helps to limit the food for the scorpions.

– Don’t allow grass to build up around the foundation.

– Don’t allow rocks to touch the stucco, always make sure you can see the foundation completely around the home – termites also find there way in by the foundation.

Control

• Seal the structure – Home sealing is one of the greatest ways to

prevent scorpions and other insects from getting into your home or business. Clear caulking works the best, if the holes are large use cooper wool – this prevent rodents from getting in as well.

Control

• Pesticide application– It may be necessary to apply pesticides and I

suggest that you try switching chemicals from the winter to the summer.• Winter – I suggest Talstar (Talstar holds up pretty well in

the winter and depending on temperatures you might be able to get by with a treatment less often) now if it is warm all winter that statement may not apply.• Summer – I suggest Transport Mikron or Demand CS

– Microencapsulated – (tiny bubbles surrounding active ingredient product).

Hire a Pest Management Professional

• Several things I have learned over the years– Most people will try to remember to do the work

but most likely will forget treatment until you notice a problem – hire a company to come out on a schedule.

– Identification is the 1st step.– Read the Labels, MSDS and use directions.– If you don’t understand – call someone.
