Detergent water, vacuum cleaners, door sweeps.
These simple household products are on the front lines of "green" pest control.
Amid a new wave of environmentalism, eco-savvy consumers are realizing they no longer need to rely on traditional pesticides, which may pose health risks, to combat rodents and insects.
Environmentally friendly exterminating services, dubbed integrated pest management, are popping up across the nation. The companies say demand for their services is on the rise.
"Traditional pest-control companies run around spraying pesticides," said Joel Sklar, vice president of sales at Assured Environments, a New York integrated pest management company. "We're using glue traps to find out where there are animals and pests . . . and we seal holes and areas to prevent them from getting in."
Instead of using chemicals, ecowarriors investigate how and why pests infiltrate a building. Then they rely on detergent water, vacuum cleaners, and low- or no-toxicity products to fight the problem.
"Probably the best product out there is a door sweep," said Tom Green, president of the Integrated Pest Management Institute North America Inc. in Wisconsin, referring to the vinyl strips installed on the bottoms of doors.
"A mouse can squeeze through a hole the size of a pencil diameter. So if you've got a quarter-inch gap underneath your door, as far as a mouse is concerned, there's no door there at all."
About two-thirds of the 378 exterminating companies that responded to a survey by Pest Control Technology magazine last year claimed to offer some sort of integrated pest management.
But most consumers are not aware these services even exist, said Cindy Mannes, a spokeswoman for the National Pest Management Association, a trade organization.
She cautioned that each of the approximately 18,000 US pest-control companies may define IPM differently.
And a typical $75 exterminator's visit to a four-bedroom home can cost clients 10 to 20 percent more if they choose such services, which are more labor intensive, according to Sklar.
Green pest control products are also in demand.
"Natural pest controls are the fastest growing part of our business," said Eric Vinje, owner of Planet Natural, an online and catalog-based organic gardening supplier.
His most popular products include Orange Guard, which suffocates insects, and Diatomaceous Earth, made from skeletal remains of plants that can cut through insects' protective shells and kill them. He also recommended boric acid-based products, like Terra Ant Killer.
"It acts as a stomach poison to insects," Vinje said. But "for us, it's about as toxic as table salt."
