The most dangerous creature to the human population
is the common housefly. The term housefly is used
to identify most of the insects in the Muscidae
family from the Diptera (two-winged) order of
flies, there are many different species of these
small, stocky flies. In most cases, any fly that
is found inside a house or building is considered
a housefly. The common houseflies can "taste"
with their feet, so they land on everything, tasting
and spreading disease. Houseflies can transmit
intestinal worms, or their eggs, and are potential
vectors of diseases such as dysentery, gastroenteritis,
typhoid, cholera and tuberculosis.
The most poisonous insects are in the order Hymenoptera
(wasp, bees, and ants) and the ones with the most
toxic venom are certain harvester ants.
