Gardening Practices to keep mosquitoes down in your yard
by Yvonne L. Bordelon
Besides ruining a day in the yard, certain mosquitoes can transmit West Nile and other diseases in their quest for the blood needed to produce eggs. In fall, mosquitoes mate and the males die.

Yes, you can control fire ants.
by Blake Layton
Fire ants. Just hearing the words will make most Southern gardeners anxiously check their shoes and the ground where they are standing. These non-native stinging ants are established in portions of 12 southeastern states, and six of these states – Louisiana, Mississippi, Alabama, Georgia, Florida and South Carolina – have fire ants from border to border.
Fire ants prefer treeless grassy areas such as pastures, roadsides, parks and lawns, and densities can reach 50 to 200 mounds per acre in areas where they are not controlled. Fire ant mounds are unsightly, but it is their stings that make them so notorious. Unlike honeybees, fire ants do not have barbs on their stingers, and this means they can sting more than once. A single fire ant sting is painful, but unsuspecting gardeners sometimes sustain dozens or even hundreds of stings as a result of unknowingly stepping in a fire ant mound. The raised white pustules that result usually persist for about a week. >> read article
