When bats decide they want to live in a specific area of your home it is crucial that you take quick action by arranging removal plans. Bats are a mostly protected species throughout the modern world, with extreme penalties awaiting anybody who mistreats them. Evicting them is no easy matter, for as well as the protection law; it also dictates that eviction can only be done at a particular time of the year. When the young of the bat are born they need to be made welcome guests until they are able to fly freely, this period will certainly last from early spring until September.
To make matters worse the quantity of bat droppings (guano) surge considerably during the time the young are being reared. Bat colonies grow in size each year, by at least doubling their population. Unlike they do not disperse and go their own way when they are fully grown, they become part of the nest and will certainly stay at the spot of their birth. So if no action is taken, the size of the problem will just grow and grow till it is completely out of hand.
