Generally, bats are animals which are beneficial to have because they eat hundreds of pests like mosquitoes and other bugs. However, if they are nesting on some places where they should not be, such as the attic, then you are probably wondering how to get rid of bats in ways that are allowed by law.
Keep in mind that in other countries like the UK, all species of bats are protected by environmental laws and it is absolutely illegal to disrupt or move them. If you think that it is necessary for you to step out of the line, call a specialist first to ensure that you will end up with no liabilities.
Bats In The Building
Choosing the right time. Disrupting and evacuating bats during the correct season is important to preserve their overall health and make sure that they survive. Try and look at what you are dealing with. If it is a nursing colony, removing the adult ones before the pups are capable of flying out will endanger them. Not only will this be inhumane, but it is also impractical in a way because you have to go through the effort of finding the carcasses and getting rid of them. For newborn bats, at least five weeks are needed for them to manage to fend for themselves. Garlic, noise, and light will not do you any good so it is better if you stay away from these old wives’ methods.
Winter is not the right time to get rid of bats. Typically, these creatures hibernate during the cold weather so there will not be enough food outside for them to survive. If the population is decimated, then you will notice more garden pests and insects during spring time.
Knowing their entry points. Try looking for guano or bat droppings below their point of entry. They contain small bits of insect shells so they look sparkly when exposed to the sun and their texture is somewhat crumbly, unlike rat droppings which are mostly made up of plant excess.
To avoid getting histoplasmosis, do not inhale the bat droppings. The elderly or the very young will experience flu-like symptoms and those who have weak immune systems will be especially prone.
If you cannot identify their entry points based on the droppings, maybe because they have not gone through that same route for quite some time, you can also observe where the creatures come from when they go out at night.
Preventing re-entry. If you have successfully evacuated the animals, you need to make sure that they do not come right back in. To know how to get rid of bats permanently, you need to do repeated sealings in your home. After they have flown out during the night to look for food, staple or nail a screen or cloth over their egress point. As they feed on a 24 or 48 hour period, go through the sealings carefully to make sure that the entire colony has been eliminated and that the mission was accomplished.
