The cost for bird and bat control services typically ranges from $300 to $1,000. The final price depends on several factors, including the size and severity of the infestation, the specific removal method used, and the complexity of accessing the affected areas.

Certain strong smells may help repel bats, though this is not a foolproof method and is best used in conjunction with other deterrence strategies. Scents like peppermint oil, eucalyptus, cinnamon, cloves, and mint are often suggested as natural remedies. To create a spray, you can mix two cups of warm water with half a cup of sugar and a few drops of your preferred essential oil. Apply this mixture using a spray bottle to possible entry points and throughout the affected area, such as an attic. While this home remedy is popular, evidence supporting its effectiveness is limited.

Using audio and visual methods to discourage birds might work initially, but birds tend to acclimate to them over time. While chemical deterrents can show some effectiveness, their results can be inconsistent. Some may dissipate too quickly, and there's a risk they might cause unintended damage to your surroundings. Additionally, birds might become immune or resistant to the impact of such treatments.

Look for goose repellents that contain the ingredient methyl anthranilate. This is a natural chemical found in grape juice. In human food, it’s often used as grape flavoring. With geese, it’s highly irritating. Grape Kool-Aid contains methyl anthranilate, the active ingredient in most bird repellents. It won’t harm geese, but it will deter them.
