Ants

Question How do we keep red ants out of potted plants? I have two hibiscuses in pots along with a couple of other plants, prepared by a gardener who works in a local nursery. I had them put together about one and a half years ago to spruce up the front entrance of my daughter¹s apt. I have them now at my place. One of them has had blossoms and the other hasn¹t. Today the ants were milking the aphids on the buds! Ants are such a problem. I want to put pots on my steps but the ants always find there way under the pot.

AnswerAnts must crawl up the pots so using some type of physical barrier can keep them at bay. The above mentioned Tanglefoot can be applied to a band and then put around the pot—the ants can’t cross it. I have also had gardeners use the hot pepper wax as a barrier and even Vaseline. It is not unusual to find ants ‘herding’ aphids. They love the sweet honeydew the aphids give off.

Question I have received several emails from friends and associates about a new cure for fire ants. Would you please consider looking into this assertion which follows: an environmentally friendly cure for fire ants has been announced. Simply pour two cups of CLUB SODA (carbonated water) directly in the center of a fire ant mound. The carbon dioxide in the water is heavier than air and displaces the oxygen which suffocates the queen and the other ants. The whole colony will be dead within about two days. Besides eliminating the ants, club soda leaves no poisonous residue, does not contaminate the ground water, and does not indiscriminately kill other insects. It is not harmful to your pets, soaks into the ground. Each mound must be treated individually and a one liter bottle of club soda will kill 2 to 3 mounds.

AnswerI have gotten the same emails and also a bunch of questions from interested gardeners. It has also been making the rounds in other fire ant states, and a response has actually been posted on the national eXtension site at http://www.extension.org/faq/36624 I posed the question to our entomologists and the overall opinion seems to be that it might make them move during the growing season but the chances of it actually killing fire ants is slim to none. The best control of fire ants is to use the UA Extension recommended 2-step program which you can view at: http://www.uaex.edu/publications/PDF/FSA-7036.pdf This would be done during the growing season when the insects are active.
