Cockroaches are one of the most primitive insects to walk the earth. They evolved about 350 million years ago, and today there are more 4,500 different species of cockroaches. The most common cockroaches to be reported, according to Pest Management Professional are the German, American, and Oriental Cockroaches.
Cockroaches can survive in almost any climate, and can live up to 42 days with no food and water. They can eat almost any plant or animal matter, making them extremely versatile and resistant to changes in environment. Some reports even claim a cockroach can live on the glue off the back of a postage stamp for up to a week!
When treating for roaches, it is important to be persistent. Sprays and baits are the best treatment, in and around cabinets, wall voids, and appliances. You can use Catch-its to trap the roaches or JT Eaton Boric Acid for Roaches to kill on contact. This powder should be applied liberally to areas where roaches frequent.
