What Repels Bats?
When bats invade your space, they bring noise, filth, and in some cases, even disease. Although rabies caused by bat bites is probably rarer than you might imagine, bats still make a mess wherever they make their home. Yet, because Colorado law protects them, you cannot exterminate them as you would cockroaches or fleas. Instead, the most common way people try to manage bat infestations is to repel the bats away from homes, schools, and other buildings where humans reside. Consider the following methods of repelling bats.
With many ultrasonic devices marketed to repel bats, it might seem like a simple way to solve your bat problem. These electronic devices emit a high-frequency sound that humans cannot hear, but that may drive bats away. You can buy an ultrasonic bat repellent device without spending a fortune, and it requires very little maintenance.
However, there is little evidence that ultrasonic bat repellent devices work. In independent testing, these devices have not been shown adequately effective. Also, these devices might disturb your pets or other wildlife that you don’t want to frighten away.
Lights and Sparkles
Shining lights where the bats go to roost disrupt their sleep, so they may leave to find another place where they can settle down. Additionally, you can use a mirror or a sheet of aluminum foil and shine a light on it to increase the light. Unfortunately, unless you illuminate every possible roosting spot, the bats will simply move somewhere darker.
Products with Naphthalene
Chemical bat repellent products might succeed in keeping bats away when electronic devices fail. On the other hand, you need to consider the safety of using such products. The most popular chemical bat repellent products use naphthalene, the same chemical in mothballs. However, these chemicals are hazardous to human health. Therefore, if you used enough of them to eliminate a significant bat problem, you could be putting your family at risk. Consequently, it is best to use naphthalene products in small areas where people and other animals do not go.
Natural Bat Repellents
Natural bat sprays are effective because bats have extremely sensitive noses and do not like the smell of the ingredients used in the sprays. For example, some bat repellant sprays have essential oils like spearmint or peppermint. Fortunately, such sprays present no danger to you or the pests. However, these sprays or packets are best for the early stages of infestation and may require frequent reapplication.
