Tropical Cockroach

One of the world's largest cockroaches comes from Africa. It is called the tropical cockroach. It has also been called the giant tropical cockroach and the giant cockroach. Its scientific name is Blaberus giganteus (L.).

This giant cockroach can reach almost 3half an inch in length. It is found in Central and Southern Africa, the West Indies, and South America. It is popular with people who keep cockroaches as pets.

The tropical region is the original home of many of the world's cockroaches. Among the most common are the brownbanded roach, the oriental roach, the Madeira roach, the brown roach, and the American roach.

These tropical cockroaches have been transported around the world in cargo containers. For many years, cockroaches have traveled by ships. During the 1850's, travelers discovered that the cockroaches on their ship had eaten all of the bedbugs that had been biting the travelers.

In more recent times, cockroaches have traveled by airplane. They also travel by bus, train, and automobile. People transport cockroaches in boxes, bags, and luggage. Cockroaches also travel inside of furniture. They hide inside of items that people buy at yard sales and thrift shops.

In the United States, cockroaches are most numerous in the Southern states where the climate is warm. The roaches can live outdoors all year. They invade homes when the weather changes and food or water become scarce.

In the Northern states, cockroaches often survive inside of buildings. Greenhouses and atriums are common homes for cockroaches. They invade basements of homes and commercial buildings. Cockroaches have even been found living in the sewers of Northern cities.

Homeowners who want to avoid a cockroach infestation can practice a technique known as exclusion. Exclusion involves a variety of ways of keeping cockroaches from entering the home.

To exclude these tropical roaches, homeowners can start outside the home. The exterior doors should close tightly. Experts suggest that there should not be a gap under the door. A space as thin as a dime can allow a cockroach to squeeze inside. Access doors for crawl spaces should close securely. The crawl space and attic vents should all be screened.

Cockroach hiding places should be eliminated. Woodpiles should be placed on racks and be moved as far away from the house as possible. Ivy and other ground cover should be trimmed back away from the foundation. Mulch and dead leaves should be raked away from the foundation. Ideally, there should be a zone of 12″-24″ next to the foundation that is free of vegetation.

Outdoors, insecticide can be effective for preventing cockroaches from invading the home. Many brands of granular roach bait are water-resistant. They can be used effectively in flowerbeds and ground cover.

Liquid insecticide can be applied as a barrier on the outside foundation. Because sun and rain break down insecticide, the barrier will have to be re-applied periodically. Many homeowners call on a pest control professional to make these applications to control cockroaches around the home.
