A Parent’s Impossible Choice

Every summer, parents face a frustrating dilemma. Do you let your children get covered in itchy, potentially dangerous mosquito and tick bites? Or do you spray them down with DEET, a known neurotoxin that carries explicit warnings against heavy use on children?

Children are particularly vulnerable to chemical exposure. Their skin absorbs topical applications more readily than adult skin, and their developing nervous systems are more sensitive to the neurotoxic effects of conventional repellents.

If a chemical requires you to wash your hands immediately after applying it, is it really safe to leave on your child’s skin all day?

The Danger of Chemical Sprays on Kids

Health authorities advise against using high-concentration DEET on children, and recommend washing it off as soon as they come indoors. But children rub their eyes, put their hands in their mouths, and sweat profusely while playing, making accidental ingestion and heavy absorption almost inevitable.

Cream of tartar and MSM sulfur powder, the two ingredients in Tarsul, in the context of insect bites and repellency
Tarsul is a fine white powder — potassium bitartrate (cream of tartar) combined with MSM sulfur — stirred into water rather than swallowed as a tablet.

Many parents turn to “natural” essential oil sprays, but these are notoriously ineffective, evaporating within minutes and leaving children completely unprotected.

Safe, Systemic Protection from Within

The safest way to protect children from insects is to change the chemical signals their bodies naturally broadcast. By introducing elemental sulfur into their daily routine, you can gently alter the volatile organic compounds they excrete through their pores.

Sulfur is not a foreign chemical; it is the third most abundant mineral in the human body, essential for healthy growth, joint development, and detoxification. When taken as a supplement, the trace sulfur compounds excreted through the skin act as a powerful, invisible barrier against mosquitoes and ticks.

Peace of Mind for Parents

Internal repellency means no more chasing kids around with a spray bottle. It means no sticky residue, no harsh chemical smells, and no worrying about what they are absorbing through their skin.
