Rodents
Rodents slip in through open doors and attic or foundation vents.
They can gnaw through furniture and electrical wires causing short-circuits to electrical appliances and in extreme cases an entire building.
They can carry infectious diseases and contaminate food with their feces and urine.
Cockroaches
Cockroaches can enter through small cracks and crevices, vents and pies,
and in grocery bags or on firewood. They produce odorous secretions from parts of their bodies
which affect the flavor of food.
Mosquitoes
From the standpoint of human welfare, mosquitoes spread diseases such as malaria, yellow fever and dengue fever.
They can be annoying, interfere with work and spoil hours of leisure time; females are blood sucking,
bite man, and they serve as vectors in the transmission of potentially fatal organisms.
Ants
Ants are one of the most successful groups of insects in the animal kingdom.
They are of particular interest because they are social insects and form highly organized colonies or nests which sometimes consist of millions of individuals.
Colonies of invasive ant species will sometimes work together and form super-colonies,
spanning a very wide area of land.
Flies
Flies are not only annoying but they can also carry harmful bacteria that
they pick up from decaying materials and spread to any uncovered food sources.
Termite
Termite is considered to be the most destructive insect pests in the world. They can enter your premises via mud trails and attack modern structures. They feed on cellulose-based material and cause damage when they feed on structural timber either indoor or outdoor.
