Getting rid of Scorpions requires a combination of both chemical and non-chemical measures. Think of non-chemical measures (such as vacuuming, sanitation, harborage removal, and exclusion) as limiting or removing conditions that contribute to the infestation. These measures are largely preventative. The next step is to come in with the real ammunition-chemical pesticides-that do the job of physically wiping out an infestation.
Step 1) Nonchemical Methods for Scorpion Control
Nonchemical methods for scorpion control are:
- Harborage Removal- Harborage removal is key to scorpion control and will greatly reduce the numbers of scorpions in the area surrounding the structure, making it far less likely that they will enter. Harborage removal includes eliminating piles of lumber, bricks, and other stacked items that create clusters of tight spaces, elimination of vegetation and other heavy ground coverings near homes and buildings, trimming back tree and shrub limbs from walls and roof, and keeping gutters clear of leaves and other debris.
- Exclusion- Scorpions and other pests can be kept out of structures to a large degree by installing tight-fitting screens, weatherstripping around doors and windows, and caulking cracks and crevices.
Step 2) Chemical Treatments for Scorpion Control
- First, apply a residual pesticide labeled for scorpions ( Demon WP Insecticide or Suspend SC both provide excellent results) with a Gallon Sprayer around the entire outdoor perimeter creating a 3 to 10 foot band, and indoor along baseboards and in cracks and crevices.
- Next, using a Hand Duster, apply waterproof residual Delta Dust Insecticide (lasts up to 8 months) underneath baseboards, inside of cracks and crevices, and behind cabinets.
- CB Intruder HPX may also be used and kept on hand for instant kill when scorpions are sighted on countertops or walls. This aerosol product may also be used around window and door frames (providing a 4 to 8 week residual).
How to Safely Capture a Scorpion
Scorpions can be captured by placing a quart-sized glass jar over the scorpion and sliding a sheet of heavy construction paper under the jar, thus trapping the scorpion. With the sheet of paper securely over the mouth of the jar, invert the jar and the scorpion will fall to the bottom of the jar. Screw a secure lid over the mouth of the jar. Scorpions can also be picked up safely with forceps that are 10 to 12 inches in length, or with other long mechanical devices made for picking up small objects, and placed in a glass jar secured with a screwtype lid. Insect Glue Boards measuring 8 x 5-1/4 inches may also be useful in trapping scorpions.
Be Smart-- Avoid Scorpion Stings!
If you have a scorpion infestation in your home, take these simple precautions to avoid painful stings:
- When picking up any object, do so carefully and inspect the underside.
- Shake shoes and clothing vigorously before wearing.
- Move beds away from walls, and keep bedding off the floor.
- Do not walk barefoot at night when scorpions are most active.
- The legs of a crib or child's bed may be placed in glass jars, as scorpions are unble to climb glass.
