Mice Infestation
In countries or areas where grain production is a major industry, mouse infestations can be severe. Populations multiply rapidly and may persist for up to two years. They are most common following harvest seasons.
Variations in farming methods, high harvest rates, increased crop storage, reduced grazing and incomplete harvest cycles may lead to infestations on previously unaffected farms. Initially, a mouse infestation may not prove overly troublesome to these farms. However, as the proceeds from the successful harvest wear off and the ill effects of the infestation become apparent, extermination is often necessary.
When mice have an unusually long breeding period or when food is plentiful, infestations may cause many months of damage at a time. Although populations as low as 100 can cause considerable damage, it is important to recognize an infestation as early as possible. Even those crops that are not fed upon by mice tend to become contaminated with mouse droppings, urine and saliva. The excrement of a number of species spreads diseases to humans and animals.
