Protect Your Property from Mosquitoes
What You Can Do As a Homeowner
- Empty or clean out all water-holding containers in your yard (bird baths, tires, cans, rain barrels, wading pools) – 1 small can of water can hold as many as 10,000 mosquito larvae.
- Keep your gutters cleaned.
- Keep ornamental ponds free of weeds, cattails, or other aquatic vegetation.
- Use anti-larval products (dunks or bits) available at local hardware stores and use them in ponds or standing water.
Adult mosquitoes are most active at dawn and for about an hour after dusk. Plan outdoor activities during warmer daylight hours or later in the evening to avoid adult biting mosquitoes.
- Keep your lawn mowed as short as possible.
- Cut back dense vegetation surrounding your yard; this is where mosquitoes hide during the day.
- Keep ornamental shrubs and bushes pruned to allow more light and air to flow through them.
Farmers & Agricultural Landowners
