Different climate zones of the world support quite different populations of plants and animals. Tropical zones generally have greater biodiversity than cooler climates. With human development of air conditioning to cool and to heat, the small sizes of many pests organism that prefer temperature climates are now able to survive and thrive in the micro-environments provided inside buildings when outside is inhospitably hot or cold.
Climate includes not only temperature or humidity but variations in length of day (light), rainfall, and wind. Animal pest organisms are often dependent on the type of plants endemic to an area and plants are less likely to thrive outside their preferred climactic zone. This is particularly relevant to termites, which almost always come from an outside colony that is subject to a prevailing climate. The fact that their natural forest has been replaced by timber wrapped in masonry or metal is something that many adapt to quite easily.
Fleas, bed bugs in Singapore and lice are portable pests given economy class, even first class transport to anywhere in the world that humans can survive.
Temperature and Life
Life depends on an extraordinarily complex arrangement of biochemical reactions that can operate only within a certain range of temperatures. Although a particular organism may be able to survive over a fairly broad temperature range, particular activities such as food seeking are usually governed by a smaller temperature range. For example, cockroaches live in the sewage system in a temperate region may survive throughout the year, but the warmer conditions of summer result in increased activity, food-seeking, flying and perhaps shorter life cycles. This would make cockroach control in summers an imperative measure. Many insects are more active and abundant in warmer conditions.

Moisture and Life
Organisms obtain life, which is essential to all life, in a number of ways: from rain, surface water, water vapor in the air and the water contained in their food. The normal equilibrium of moisture content of grain and wood is sufficient to support the activities of insects that specialize in these materials. Humidity can influence the activity of various organisms. Termites’ colonies can create and maintain the very high relative humidity that promotes their development.
Light and life
Over a million years many organisms have established a pattern of activity that is governed by the regular cycle of light and its absence – Day and night. Cockroaches and rodents often sharing accommodation with humans, are active mostly at night (or perhaps more accurately when the lights are out). Such night activity organisms are referred to as nocturnal.
So defined is this pattern that it is not uncommon for infestations to exist without the human occupants being aware of them.
Familiarity with the ecology of pests and the environment in which they thrive is a most important first step in their management.
