Pyranha Zero-Bite® Natural Insect Spray offers fly control the way Mother Nature intended: with zero chemical pesticides. The goodness of Geraniol, an oil derived from fly-deterrent geranium, combines with clove oil and peppermint oil for a powerful natural alternative to traditional fly sprays. The natural oils are suspended in more than 90% water, so it is neither oily nor greasy, and has a great natural scent. It's effective against stable flies, house flies, bot flies, horse flies, horn flies, ticks, deer flies, mosquitoes, fleas, face flies, gnats, and lice.
