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.

There are DIY methods and store-bought pesticides available for the public to use. However, these pesticides also come with a risk, and you need to follow the directions correctly and take precautionary measures to prevent exposure to these chemicals. These methods may be an option for small pest problems, but you should call in a pest control specialist for persistent pests and infestations.

No, you shouldn’t have to worry about bats in your yard as long as they don’t make their way inside your house. Typically, bats hang around backyards in order to consume bugs, especially if they’re located in the U.S. Bats that are native to North America can consume more than 500 bugs per hour, so they may actually benefit your yard if mosquitoes are prevalent.

When it comes to keeping birds from doing their business on your porch rails, you have several DIY options and home remedies you can try: 

• Tie a fishing line from one end of the deck post to the other. Birds won’t be able to see the line across the railing, so they can’t land on it.  

• Hang wind chimes close by, which may scare birds away. 

• Apply a bird gel repellent to the railings, which contains smells that birds generally don’t like. Or, similarly, you can apply citronella or lemon oil around the railings, since birds don’t like strong smells.
