The Mosquito’s Hunting Mechanism

To understand how to repel mosquitoes from the inside, you first have to understand how they find you. Mosquitoes do not hunt by sight; they are chemical trackers.

They follow plumes of carbon dioxide from our breath, but CO2 only tells them a living creature is nearby. To pinpoint a human target, they rely on highly specialized olfactory receptors that detect specific volatile organic compounds (VOCs) secreted in our sweat and sebum.

If mosquitoes track us by our unique chemical signature, what happens if we change that signature?

Altering Your Chemical Broadcast

Topical sprays attempt to overwhelm or block the mosquito’s receptors temporarily. But internal repellency takes a much more elegant approach: it changes the actual VOCs your body produces.

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.

When you consume specific compounds—most notably, elemental sulfur—your body metabolizes them and excretes the byproducts through your pores. While these trace sulfur compounds are imperceptible to human senses, they act as a powerful deterrent to a mosquito’s delicate olfactory system.

Instead of broadcasting “food,” your skin begins to broadcast a signal that mosquitoes naturally avoid.

The Superiority of Systemic Protection

Repelling mosquitoes from the inside offers several distinct advantages over topical applications:

Full-Body Coverage: A spray only protects the exact patch of skin it touches. If you miss a spot behind your knee or on your ankle, a mosquito will find it. Internal supplementation protects your entire body evenly.
Continuous Defense: Topical sprays evaporate, rub off on clothing, or get washed away by sweat. Systemic protection remains active as long as you maintain your daily supplement routine.
No Chemical Exposure: You avoid absorbing neurotoxic chemicals like DEET or dealing with sticky, foul-smelling lotions.

How Tarsul Provides Internal Defense

Tarsul is specifically formulated to provide the bioavailable sulfur required to alter your skin’s chemical signature. By taking Tarsul daily, you build and maintain the internal mineral levels necessary to keep mosquitoes at bay, naturally and safely.
