The idea of parasites living in soil is the stuff of horror movies. Unfortunately, adult parasites and their eggs actually do inhabit soil, grass, sand and a variety of other ground material. Walking and spending time on infected soil puts you at risk for contracting parasites, as does eating food that is grown from it. You must eliminate them from the soil to keep your family and your pets safe.
Sprinkle 10 lbs. of sodium borate per every 100 square feet of soil to kill parasites such as hookworms. Sodium borate will kill vegetation, therefore, only use it if you do not mind killing your grass. Sodium borate is typically available at pharmacies and hardware stores. Keep any pets and children away from the lawn if you apply this substance, as it is potentially harmful.
Allow the infected soil to be exposed to frequent sunlight, if possible. Many parasites and their eggs will die quickly if they feel the heat of the sun for long periods of time. Clip tree branches or hedges to let the sun to beat down on the infected soil to help kill the parasites, their larvae and their eggs.
Remove infected soil, if possible. Some parasite eggs are resistant to most forms of treatment and can remain in the soil for years. You must often remove the soil and replace it with clean soil. If that’s not possible, attempt to overturn the soil to a depth of 8 to 12 inches.
