Having bats in your home can be a daunting and problematic situation. These fascinating creatures might seem harmless, but they can pose serious risks to both your health and your property. In this blog post, we will explore why bats are considered one of the most problematic wildlife species to have in your home.

Histoplasmosis: A Silent Threat

One of the major issues associated with having bats in your home is the risk of histoplasmosis, a potentially life-threatening fungal infection caused by Histoplasma capsulatum, a fungus found in dried bat guano. When the droppings dry out, they can break down into fine dust that carries the fungal spores. If these spores are inhaled, they can cause flu-like symptoms such as cough, fever, fatigue, and chest pain. In severe cases, histoplasmosis can lead to chronic lung disease or even death. It is essential to take proper precautions and avoid any contact with bat guano to prevent this dangerous infection.

Home Damage: A Costly Consequence

Alongside the health risks, bats can also cause significant damage to your home. Bats are known to roost in attics, chimneys, and other dark, confined spaces. They can squeeze into tiny openings, causing structural damage and compromising the integrity of your home. Their droppings can accumulate over time, leading to a foul odour and staining ceilings and walls. Moreover, bats are nocturnal animals, meaning their activities can disrupt your sleep and cause stress.

Humane Exclusion Methods

It is crucial to address the bat infestation in a humane manner that respects the protected status of bats in Ontario. Instead of using harmful methods, consider using bat doors and prevention work to exclude them from your home. Bat doors, also known as bat valves or one-way bat cones, allow bats to exit your home but prevent them from re-entering. By installing these devices in the bat’s entry points, you can encourage them to seek alternative roosting sites without causing any harm.

In addition to bat doors, implementing prevention work can also be effective. Start by sealing any cracks or gaps in your home’s exterior, paying close attention to areas where bats might gain entry. Ensure that vents, chimneys, and other potential access points are properly screened. By eliminating potential entry points, you can discourage bats from returning to your home.

Protected Species: A Legal Consideration

It’s essential to understand that bats are protected species in Ontario and harming them or their roosts is illegal. Before taking any action to remove bats or their guano, it is recommended to consult with local wildlife authorities or hire professionals specializing in humane bat removal. These experts have the knowledge and experience to safely handle the situation while complying with the law and ensuring the well-being of the bats.

In conclusion, bats can become a significant problem when they invade your home. The risk of histoplasmosis from dried bat guano, potential damage to your home, and legal considerations surrounding protected bat species in Ontario are all compelling reasons to take immediate action. By employing humane exclusion methods and seeking professional advice, you can safely and effectively deal with the presence of bats while protecting both your health and the environment.
