They’re back. Those pesky mosquitoes begin to reproduce rapidly in spring and are looking for their favorite food: blood. Some will fly several miles seeking a meal, which could be you relaxing on your deck.

Mosquitoes can be controlled around your property. Eliminate breeding sites wherever water collects and remains stagnant for several days. Get rid of old tires, buckets, tin cans, tarps or other containers that collect and hold water. Drill a hole in the base of tire swings for drainage. Change the water in pet dishes, bird baths and wading pools every two days. Stock ornamental pools with top feeding minnows and clear rain gutters of debris. When not using a boat, cover it or open the drain plug. Low-lying areas on your property should be drained. If unable to drain wet areas, consider Bti (Bacillus thuringiensis). It has proven very effective, yet is safe for the environment. The bacterial spores attack mosquitoes during the larval stage, when they are most vulnerable, but are harmless to warm blooded animals and beneficial insects. Other safe and effective pesticides available are mostly made of mineral oil with emulsifiers, allowing the mineral oil to spread evenly on the water’s surface. The larvae then can’t breathe and die.

For outdoor events like reunions, graduations or weddings, a fogger can be used. The ingredients in foggers can be hazardous, so read and follow label directions for safe use or hire a certified company to do the work. Begin fogging at least one week before the event at sunset or early morning. Apply to foliage where mosquitoes reside. Do not fog when windy, especially if winds are 10 mph or more.
