Even though bats are considered to be relatively good animals, the looks of a bat can be both startling and scary for people who stumble upon them in the attic or even inside the house. Apart from the fact that they are disease carriers and their droppings can be infectious, they largely help humans by eating off blood sucking insects like mosquitoes and moths.
Most people do not like bats in their house and have searched for ways to get rid of them. A lot of these people in turn look for repellents that would deter the bats from entering the house, but the effectiveness of repellents in getting rid of bats is questionable as they rarely solve the problem. Several types of natural and chemical bat repellents exist and are generally available for interested homeowners.
Mothballs are effective at dealing with and getting rid of bats but while they might be harmful to bats, they are also harmful to humans and can cause cancer. The Naphtalene smell of mothballs is so strong and touching it alone can trigger sensitivities to the substance. It works best when used in closed up spaces.
Bright lights placed at entry or exit points may be combined with mothballs or used alone. The nocturnal animal finds it offensive and may leave for another den. The downside is that the bats are likely to look for and fly to the dark corners; bright lights also invite more pests into the space, like moths and mosquitoes, both of which are food for the bats.
Loud noises also make your attic less conducive for the bat, but for how long? They don't work, because bats crawl into tight spaces away from sound. They also just don't seem to care. Read Bright lights & loud noises for bats — does any of it work?

4-THE-BIRDS GEL: This is available in calking tubes and is applied with a special calking gun. It can be used on a bat's roost sites both those inside the house and externally. The gel is sticky and very thick. It adheres to the surface and can stay for a long period. Whenever a bat lands on the gel, it leaves. The gel can be used for entry points and louvers vents.
4-THE-BIRDS LIQUID: This is the same material as the gel but comes in a liquid form which is sprayed on hard to reach entry spots. The substances in this product aren't harmful to the bats; they only create a surface that the bats would want to avoid.
PEST RID: This is another granule or liquid product that is believed to be harmless to the bats. They release tastes and odors that bats cannot withstand. Spray on their hiding points and the entry points. This solution is effective for a month at the most.
