Here are the three main ingredients in non toxic bedbug sprays:
Sodium Lauryl Sulfate
Sodium lauryl sulfate is used in many personal hygiene products i.e. soaps, shampoos, toothpaste, etc. It is also used in cleaning products such as dishwashing liquid. It causes the product to "foam up" so you can lather it on your face, teeth or your dishes. To most people, sodium lauryl sulfate is harmless. But to some, when in direct contact with it, it causes a rash-like reaction. It attributes to skin problems like perioral dermatitis, which causes red bumps, inflammation and an eczema-like rash on the face. Make sure no one in your family has this allergy before spraying.
Sodium chloride is salt or saline. It is the salt that is in the ocean. We know it as common table salt. To have a salt allergy is pretty much impossible. Sodium chloride is not a chemical per se, but it is used in non toxic sprays.
Potassium sorbate is the potassium salt in sorbic acid, which is a natural organic compound. Sorbic acid is used as a food preservative. Potassium sorbate is used in baked goods, cheeses, wines, yogurt, etc. Many people ingest potassium sorbate on a daily basis, but do not realize it. People do have allergies to potassium sorbate. In fact, bakers who have large amounts of exposure to it can have allergic reactions such as hives and skin/eye irritations. So be safe and make sure no one in your family has this allergy.
Now that you know about the chemicals in non toxic bedbug spray, you can protect yourself, your family and pets. Make sure to always check labels and research all chemicals. You never know when you may be allergic to a seemingly harmless chemical.
