Having studied termites for the past 11 years, Brian Forschler
is constantly making new discoveries about them. His most recent
research shows how deceptive termite control can be.

Forschler, an entomologist with the University of Georgia
College
of Agricultural and Environmental Sciences, is studying the use
of control populations. One group of termites remains untouched
throughout the research project.

Do-nothing Approach

"If you look at one of our control groups and use the
criteria the industry uses to claim success, we can successfully
control termites by doing nothing," he said.

How can that be?

"They see termites. They put out a bait," he said.
"And if the termites aren’t there two to three months later,
they claim they’ve eliminated them."

Forschler’s research shows that not all termites in home lawns
are eliminated when baits are used.

"Sure, the baits will kill termites if they’re placed
where termites are," he said. "But we’ve found that
termites move around a lot naturally. If you do nothing, they’ll
move and come back."

Industry Uses Zero-Tolerance
Level

On farms, entomologists monitor row crops for pests, Forschler
said. And when the population count gets to a certain level, they
make control decisions. This method isn’t used when controlling
urban pests.

"The pest control industry sticks baits in the ground
and records the presence or absence of termites," he said.
"They have a zero tolerance level when it comes to termites.
They’re treating wherever they find termites."

Forschler says killing termites at the site of the termite
bait doesn’t control termites that may be found just a few feet
away or termites that may arrive later.

"There’s no doubt the baits kill termites. But do they
impact the termites in your yard that aren’t in your house?"
he said.

"I can find termites in every yard in Georgia because
I know where to look," he said. "But what is the value
of killing these yard termites? Does this make a difference as
to whether your house is going to be infested?"

Forschler is working to answer these and many more questions
centered around controlling termites.

Termite Control is an On-going
Process

"People think you can control termites by calling someone
to come out, treat your house and go away," he said.
"Termite
control is an ongoing process. Not an event. The mind-set has
to change."

Termite control should be centered around a home inspection,
he said.

"The pest control operator should come out, look really
hard — using all of his experience and tools — and find all
the areas of the house that are vulnerable to termites,"
he said.

"Then when the termites show up," he said,
"different
treatments should be used for the conditions present. It’s just
like a doctor prescribing medicine. The same medicine doesn’t
work in every case."

Forschler and other UGA CAES entomologists share their
research
findings with the pest control industry through training programs
at the Georgia Household and Structural Pest Control Training
Center in Griffin, Ga.
