Legal considerations include adherence to local and federal wildlife protection laws, particularly for species that might be protected or endangered.

Numerous predators kill hornets, including frogs, birds, lizards, bats, spiders, and hedgehogs. Some larger predators, including rats, skunks, and racoons, will occasionally attack a hornet nest in order to eat the larvae inside. These natural predators typically don’t eat enough hornets to make them an effective form of hornet control. 

Rabbits face a range of formidable adversaries in rural and suburban areas. Natural predators such as hawks, foxes, bobcats, raccoons, coyotes, and weasels pose significant threats to their survival. These skilled hunters target bunnies for food, contributing to regulating rabbit populations. Outdoor housepets can be enemies, too, particularly dogs and cats. And loud little humans playing in your yard make great rabbit deterrents, too.

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.
