Take precautions to fight mosquitoes and insects

This weekend, Ann and I are headed to the Dirty Dozen 4-H Camp with seven 4-H'ers and one counselor from Bourbon County, along with nearly 350 other youth and agents.

Rock Springs Ranch is neatly tucked into the Flint Hills area south of Junction City, surrounded by creeks, timber and nature. Therefore, we are certain to have our run-ins with mosquitoes and other irritable insects.

According to Kansas State University entomologist Ludek Zurek, nothing repels mosquitoes better than products containing DEET (for skin and/or clothing) or permethrin (for clothing only). For kids, a product labeled for kids or a soy-based product should be used, realizing it will have to be reapplied more often.

The amount of the ingredient a product has, the longer its effects will last. But that does not mean one should use the strongest product out there.

It is recommended that adults not use a product with more than 33 percent DEET. The strongest is not better; it refers to how long the product will remain effective.

A product with 20 percent will repel insects for four to five hours, which for most is long enough or will provide enough time to re-apply.

He also warns that when applying a sunscreen product and DEET at the same time, the effectiveness of the sunscreen can be reduced as much as 33 percent.

There are ways to cut down on the number of mosquitoes in your yard. Populations can be controlled by:

* Adding goldfish or guppies to standing bodies of water or adding an aerator.

* Clean and replace water in children's pools, birdbaths and water bowls at least once a week.

* Eliminate and regularly empty other items which collect water such as clogged gutters, toys, buckets, wheelbarrows, empty cans and bottles, old tires, etc.

* Make sure all windows and doors are bug tight.

* During summer months, mosquitoes are most active from dusk until dawn.

* Place netting over infant carriers.

* Mosquito traps based on the release of carbon dioxide or ultrasound technology are not effective for reducing the nuisance level.

Enjoy your time outdoors by following these recommendations to help reduce the mosquito populations and to protect yourself and your children.
