Hartz Nature's Shield natural flea and tick sprays with cedarwood oil and lemongrass oil.

Made from
Plant Based Ingredients

Cedarwood oil is derived from the needles, leaves, bark and berries of cedar trees. Similarly, lemongrass oil is extracted from the leaves and stalks of the tropical, grassy lemongrass plant.

Both herbal substances are a natural insect repellent, and have been proven to be lethal to fleas, flea eggs, flea larvae and ticks due to their ability to disrupt the insects’ nervous system function.
Hartz Nature's Selection is made with plant based ingredients.

Protection

When fleas and ticks are exposed to the cedarwood oil extracts in Hartz Nature’s Shield, pheromones are disrupted which disorient the insect and interfere with fundamental processes like breathing which can ultimately kill the insect.

Lemongrass contains a high concentration of the chemical component citral which increases the pesticidal activity of the formulation. The formulation also kills flea eggs and larvae to put an end to an active infestation. The lingering scent of the botanical oils then work to act as a barrier of entry to newly arriving fleas and ticks.
