Subject: LEAFCUTTER ANTS
I have not had any success with the products that are currently
being sold for killing Cut Ants. In desperation I called Red River
Products to order some Volcano which I had used previously and
which killed two large mounds very effectively. The gentleman
at Red River Products returned my call and informed me that the
company that manufactured Volcano was bought out and that there
was not enough demand for Volcano, consequently no more Volcano.
HELP, what do we do now?
There’s apparently a long, sad story about the loss of
Volcano, but I won’t try to recount it. Right now the best
options are: (1) Grant’s Kill Ants – not highly effective,
but does work about 30% of time, according to Texas Forest Service.
(2) New Ambrand’s version of same bait, to be called Ant
Block Home Perimeter. Not sure who’s going to sell this.
Effectiveness, I’m guessing will be about the same as Grant’s.
(3) One of the insecticide dusts registered for control of ant
mounds (Orthene (acephate), Bayer Advanced Lawn Fire Ant Killer
Ready to Use Dust (cyfluthrin), or deltamethrin dust (Terro Brand)).
Dusts can work if blown into multiple nest entrances. I recommend
a garden duster capable of blowing it into the nest. Be careful
about using Orthene (acephate) in the vicinity of a home, however,
because of it’s potential for causing a stink. There is
a new product that some folks hope will reach the market this
spring. It will be called BES-100. It’s an orange-pulp based
bait, and it is supposed to be a little better than Volcano. I
don’t know whether the label will include urban landscapes
or not. Active ingredient is fipronil. Apparently the holdup is
at the EPA because of concerns about the environmental fate of
fipronil. Lastly, the most effective approach may be to simply
protect your sensitive plants with a permethrin spray. Not a perfect
solution, and it won’t get rid of the ants, but it does
confer some protection on valuable plants. I hope this helps.
