Open warehouse doors issue an open invitation to
birds. Inside, the high rafters offer warm shelter and a
natural nesting niche for birds of all feathers.
Wendell Murphy, vice president of an Avis rental car
franchise and an air-freight trucking business in
Lexington, Ky., knows the habits of birds all too well.
"For a dozen years, we tried to keep the birds out of
our 4,000-square-foot warehouse at the airport," Murphy
says.
Numerous varieties of small birds invaded, attracted
by the 15-foot ceiling and by the potential of
uninterrupted roosting space.
"Last spring," Murphy reports, "the problem got worse
as insulation in the ceiling was deteriorating."
Driven in by spring rains, the birds nested wherever
the insulation pulled loose, creating convenient pockets
for nests – "up and behind the insulation, where it was
warm and dry," Murphy describes.
Look Out Below
Murphy minces no words about the nuisance created by
the incoming birds.
"Droppings hit the freight and the floor and got on
packages and equipment," he says. With birds nesting in
the rafters and in the sagging ceiling insulation, "it
was a mess," he says.
The warehouse/dock was a major hub of activity, with
trucks loading and unloading on one side and airplanes
on the other side. The doors were open all summer for
receiving and dispatching. A cure for the scourge of
small birds was badly needed.
If at First You Don't Succeed …
Murphy and his crew tried many remedies.
"We washed the building with high-pressure cleaners.
It did not get rid of the birds," he says.
They tried rubber snakes and artificial owls in the
rafters.
"It didn't phase them," Murphy says.
One employee tried rifle shot.
"That didn't suit me," Murphy is quick to point out.
"I like birds, and rifles would put holes in the
ceiling."
Murphy took his next lesson in bird deterrence from
the Lexington Airport.
"The passenger terminal has a big overhang," he says.
"The airport facilities' manager, who is also an
engineer, told me they used an ultrasonic device
successfully to avoid problems at the passenger check-in
area."
The facilities' manager recommended a product
manufactured by Bird-X Inc., a Chicago-based company.
The unit uses a high-pitched, variable sound above the
threshold of normal human hearing but which is annoying
to birds.
Preparation and Installation
Murphy ordered a QuadBlaster QB-4 unit from Bird-X.
"We read the instructions and followed them to the
letter," he says.
Because of the excessive deterioration, Murphy's crew
erected scaffolding to get the birds out, cleaned up the
mess and secured the insulation with wood strips. They
then washed the whole building with high-pressure hoses.
"It's very important to prepare the site properly
before installing the unit," he says. "We placed the
QB-4 unit about 10 feet above the floor and away from
the dispatchers' office."
The unit is small – about 8 inches square and 2
inches thick, he says – and easy to install.
"It worked wonders for us," he says. "We had no more
trouble. Birds fly in, land on the rafters, and fly
right out. The unit bothers the birds by emitting a
high-pitched tone that birds don't like. It surely
eliminated our problem."
Benefits Flock In
Now the warehouse is clean. "No more mess," Murphy
states. "And our employees feel better now because the
dock is clean. It perked up morale because employees
understand that management does care."
Murphy cites the health factors that were of concern.
If bird droppings are allowed to accumulate, he
suggests, they can release unhealthy gases. "We
corrected the problem, and employees appreciate it," he
says.
Murphy also notes the savings in clean-up costs.
"Anybody in the warehouse business probably has a
problem with birds," says Murphy, who has been in the
business for 42 years. "We spent less than $600 to get
the job done. I would have been willing to spend ten
times that.
"I've looked for years for something like this. I'm
happy that someone told me about it. Without this
ultrasonic solution, our bird problem would have
multiplied ten-fold."
Murphy is also happy that the unit does no harm to
birds.
"I enjoy birds," says Murphy, who has been blind
since 1965. "I like listening to them, and I have bird
feeders and bird baths around my home."
A Second Opinion
Ray Salvesen is warehouse supervisor for Comdisco
Inc., a technology services company that uses a
warehouse near Chicago to recondition and store
high-tech equipment. Salvesen explains Comdisco's
special problem with birds.
"We were looking into installing motion detectors as
a security measure, and we didn't want birds setting off
the alarm system," he says.
And there was another problem: "Prospective customers
tour the facilities," Salvesen says. A scene of dead
birds and excrement dripping on equipment would not be a
pretty sight.
Many varieties of birds – sparrows, blackbirds,
robins and starlings – were coming in the dock doors and
nesting in the warehouse's three enclosed docks. To
deter the birds, Salvesen first considered mounting
flashy tape and balloons, but he didn't think that would
be sufficiently effective since the birds had already
nested.
Doing It Right
Then he heard about Bird-X's ultrasonic unit.
"We bought one and installed it about 35 feet up in
the beams of one of the docks," he says, after he and
his staff removed existing nests and applied steel wool
and mesh screening to deter repeat visitors. "We noticed
that birds came in, perched in one spot a minute or two,
tried another spot, and then flew out. Soon they stopped
coming in at all.”
"I was leery at first," Salvesen says. The QB-4 was
installed during the month of May. "Winter would be the
true test," he says. The test of the QB-4 during
wintertime was indeed successful. "They didn't come in
at all," he states.
Since the QB-4 worked so well in one dock, Salvesen
installed another unit in the second dock.
"We didn't need one for the third dock," he says; the
two ultrasonic units covered the territory adequately.
Conclusion
Warehouses and birds don't mix well. Birds create an
unsightly and unhealthy environment for employees,
customers and visitors. Bird droppings, besides creating
costly clean-up problems every day, can damage stored
products and warehouse equipment. Many facilities'
directors have found that one reliable and unobtrusive
way to control or eliminate the nuisance is to install
ultrasonic devices. The high-frequency sounds
effectively "bother the birds away" without harming
them, keeping the warehouse building and dock areas
shipshape and safer. To learn more about such solutions,
