Drink fluids even when you don't feel thirsty. Take frequent breaks and get out of the sun. Wearing a brimmed hat and clothing that allows perspiration to evaporate quickly will help, too. Bugs are the bane of many outdoor adventures. Not only are mosquitoes and ticks pests, but the creatures also can transmit disease.
Mosquitoes are most active early in the morning and at dusk.
But check with a doctor before applying any repellent on young children. Often a better way is to apply it to their clothing, not their skin. Wear long-sleeved shirts and pants and tuck your pants into your socks. Pest repellents that contain DEET also can help. When outdoors, make frequent inspections for ticks.
