The CDC health advisory states “Veterinary formulations intended for use in large animals such as horses, sheep, and cattle (e.g., “sheep drench,” injection formulations, and “pour-on” products for cattle) can be highly concentrated and result in overdoses when used by humans. Animal products may also contain inactive ingredients that have not been evaluated for use in humans. People who take inappropriately high doses of ivermectin above FDA-recommended dosing may experience toxic effects.”
Incorrect use of any pesticide can lead to injury, negative health impacts, or severe illness. Be sure to always read and understand the label when using pesticides and only use them where specified on the label. As a reminder, disinfectants are pesticides too, and should be used properly to minimize health risks.

Mosquitoes that can transmit WNV breed in aquatic environments like ponds or other sources of stagnant water such as roof gutters, bird baths, and swimming pools.
You can minimize mosquito habitat in your landscape by:
- Cleaning rain gutters and downspouts to remove debris.
- Sealing rain barrels. Keep all filters and prefilters clean and free of moisture-retaining debris and inspect regularly for leaks.
- Maintaining quality in swimming pools with chemical treatments. Cover or drain water from plastic pools when not in use.
- Turning over any unused garden pots, children's toys, and other objects so they don't hold water.
While working outside, be sure to wear long-sleeved shirts, pants, socks, and a hat when mosquitoes are present. Use insect repellents that contain DEET, picardin, or oil of lemon eucalyptus and reapply according to the label instructions.
