Termites live in colonies that, at maturity, are numbered from several hundred to several million individuals. Colonies use a decentralised, self-organised systems of activity guided by swarm intelligence to exploit food sources and environments that could not be available to any single insect acting alone. They have highest level of social organization in a hierarchical classification. Termites are sometimes called "white ants", though they are not closely related to true ants.
Termites mostly feed on dead plant material, generally in the form of wood, leaf litter, soil, or animal dung, and about 10% of the estimated 4,000 species (about 2,600 taxonomically known) are economically significant as pests that can cause serious structural damage to buildings, crops or plantation forests.
Term There are about 4,500 species of cockroach, of which 30 species are associated with human habitations and about four species are well known as pests. Some cockroaches have been known to live up to three months without food and a month without water.
They prefer warm climates and considered "cold intolerant” but, are resilient enough to survive occasional freezing temperatures. This makes them difficult to eradicate once they have infested an area.They feed on human and pet food, and can leave an offensive odour. They can also passively transport microbes on their body surfaces including those that are potentially dangerous to humans.
Rats have acute hearing, are sensitive to ultrasound, and possess a very highly developed olfactory sense. Their average heart rate is 300 to 400 beats per minute, with a respiratory rate of around 100 per minute.
Rats carry a number of pathogens which can result in disease, including Weil's disease, rat bite fever, cryptosporidiosis, Viral hemorrhagic fever (VHF), Q fever and hantavirus pulmonary syndrome .
