The cold climate of Iceland is one of the reasons that the country doesn’t have flies. Iceland experiences three major freezes per year and only one major thaw. In addition to being incredibly cold, the soil and water in Iceland are also thought to deter mosquitoes.
Flies are a nuisance pest that can contaminate food with harmful bacteria and disease-causing pathogens. They are most commonly found in rural areas or suburban areas near bodies of water. These pests can lay up to 150 eggs at a time. They can also enter the house through open windows.
Flies are classified in two orders. The order Diptera is made up of true flies and filth flies. A pair of flies can lay 120 eggs at a time. Scientists have calculated that a pair of flies can produce up to 191 billion house flies in five months. Despite the high numbers of flies, most people only encounter four types at a time.
There are more than 120,000 species of flies around the world. More than 18,000 species can be found in North America alone. Many of these species are pests, spreading disease and causing illness.
