Cockroaches
The two main species of cockroach in the Philippines are the American cockroach which is dark brown in color and about 30mm long and the German cockroach which is light yellowish brown, and about 12mm long. Both species bodies are divided into three sections and have long antennae protruding from the head. Immature stages look just like the adults on a smaller scale. There may be a distinctive odor due to the presence of Cockroach infestation.
Cockroaches are generally found indoors, in areas such as cellars, basements, kitchens, bakeries and heating ducts. Cockroaches can survive outdoors. Cockroaches will often remain hidden during the day using cracks and crevices as harborages. This means that in most cases they will not be evident during the hours of daylight. Most species can climb with ease, especially the German cockroach which can climb smooth vertical surfaces. Cockroaches can survive for several months without food, but will not live for more than a few days without water. Cockroaches are capable of carrying the organisms which cause food poisoning in humans and many other bacteria. They will feed on almost anything, including refuse, fecal matter and food for human consumption.
