Bark Scorpions Brought Here on Plants and Mulches Where Bark Scorpions Live

Q. I am hearing that some of the palms and rock are bringing in scorpions. 

A. It is very possible that bark scorpions are being transported here on plants and nursery materials that are coming from desert climates where bark scorpions are common. If plants and nursery materials are coming from places where bark scorpions are not common, then they are probably not going to be a problem. 

Black lights at night help you to see them.

This is not true of Viragrow mulches. They are delivered to Las Vegas from parts of southern California which do not have bark scorpions.

          I have heard the same comment made about landscape mulches. Those mulches originating from nondesert areas most likely do not contain scorpions. That doesn’t mean they can’t be infested once they arrive here.

          If you have some concerns about bark scorpions then investigate your landscape in the evening hours with a black light to see if their present. Many common insecticides used to control spiders are very effective in controlling bark scorpions.

          Now is a good time of the year to make a foundation spray around the perimeter of the house to establish a barrier that these critters are less likely to cross. In the next month outdoor critters will be trying to stay warm and looking for food. Your warm house during the cool evening or night is a magnet for drawing all sorts of critters.
