American Cockroach [BLATELLA AMERICANA]

It is the largest of the common species, growing to 1.5 inches or more in length. It is reddish-brown in colour. Both the male and female are fully winged.

Young nymphs are grayish-brown and each will molt 9-13 times before reaching maturity. After the first few molts, nymphs become more reddish brown in color. The time required to complete the nymphal stage varies from 160-971 days. Under ideal conditions, an adult female can live up to 14-15 months;

When indoors, the nymphs and adults are usually found in dark, moist areas of basements and crawl spaces as well as in and around bathtubs, clothes hampers, floor drains, pipe chases and sewers.

The adults can survive two or three months without food, but only about a month without water. The adults have well-developed wings, but seldom fly. They are capable of gliding long distances and will cover considerable distances if they take off from a tree or roof top.

German cockroach [Blatella Germanica]

Cockroaches will eat almost anything: left-over human food, paper, wood, leather, cigarette butts, tooth paste, coffee grinds, glue, soap, feces, fabric, shoes, paint, the glue on the back of wallpaper, human hair, fingernails. In fact, they can eat just about everything!

These insects are extremely filthy and reproduce very rapidly. Their movement and activity spreads bacteria and diseases and their presence anywhere near humans is unacceptable.

Further Information

The German cockroach is the most common house-infesting cockroach and the number one pest in the world.

The cockroach can live without its head for an entire week – without its head it will starve to death!

If cockroaches cannot find any food they will eat each other!

Many species are able to fly well, although the familiar household species do not fly.

There are about 4,000 different species of cockroaches in the world and the world’s largest roach lives inSouth Americaand is 6 inches long with a one-foot wingspan.

Cockroaches have been around for a lot longer than humans! Fossil evidence indicates its extreme abundance during the Carboniferous period, about 350 million years ago. These ancient cockroaches were able to fly and were probably the first flying animals.

Left unattended with enough food and water, the adult pair of a male and female German cockroach and their offspring can produce 300,000 more roaches in one year.

The two species that infestMaltaare the American and German cockroach.

As they are active in all ranges of temperature, treating against them is a year-round process.
