Ways to protect yourself from mosquito bites

Avoid being outdoors around dusk and dawn, this is when mosquitoes are most active.
Wear Long sleeves and pants when outdoors.
Use insect repellent containing 20% DEET, Picaridin or Oil of Lemon eucalyptus. Make sure you apply as directed on product label.
Inspect your yard for containers that are holding water, dump them out if they can hold water up to 5 days or more.
Set up a box or oscillating fan on your patio, set it to create a 7-10 mph wind. Mosquitoes can not fly in higher winds.
Make sure you have screens on all windows and doors.
Avoid being in heavily shaded or wooded areas.
Nothing can prevent all mosquito bites, but taking these steps can greatly reduce the number of bites.
Remember, Mosquito populations fluctuate during the summer months. On average, mosquitoes live 14-20 days
