After 300 Million Years, Roaches Still Sickening By
Faith Peppers.

Roaches Recent reports
that cities like Houston, New York, Miami and Atlanta have roach problems don't
surprise many. Roaches are an age-old problem, and they don't seem to be going
away. "Roaches have survived for more than 300 million years," said Paul
Guillebeau, an entomologist with the University of Georgia Extension Service.
"They have changed very little, according to fossil evidence." A study by Combat
Insect Control Systems ranked Houston as the 12th most cockroach infested city
in the nation. Los Angeles topped the list. The study was based on 1996 sales of
roach control products. Roaches come in more than 3,500 varieties. But you can
tell most from other bugs by their flat, long, tinny, oval-shaped, brown bodies.
The adults typically have wings. "The most common varieties in the United Sates
are the German, brown-banded, American, Oriental and Smokey brown cockroaches,"
Guillebeau said. They range from about a half-inch for German cockroaches to two
inches for American adults and up to a little over 1-1/4" for Smokey brown
roaches. "You usually find larger populations in cities," he said, "due to the
number of apartment buildings. And the climate has some effect." Cockroaches
need three things to form a population: food, moisture and shelter. "Apartment
buildings usually provide all of these," he said. "Once a few get established,
it doesn't take long for a huge population to form." So how do you keep a
population of roaches from taking over your home? "Be scrupulously clean,"
Guillebeau said. "Even a crumb is a feast for a cockroach." He recommends
cleaning the kitchen every night and putting away all food, including pet food.
"Roaches like pet food as much as your pet does," he said. He also warns you to
quickly fix leaks in the kitchen or bath, because even small amounts of water
will attract roaches. Some factors out of your control, such as climate, attract
roaches, too. "Some roaches come in from outdoors, like Smokey browns, and they
like warm climates," Guillebeau said. "Others like German cockroaches live
almost exclusively indoors, and the outdoor climate doesn't matter to them."

These are the three primary roach problems
here in Houston that keep pest control operators busy year round.
