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.

It is highly unlikely that fleas will go away on their own without treatment. Female fleas can lay dozens of eggs per day—up to 50—causing their numbers to multiply quickly and spread throughout your home. An adult flea can live for around 100 days or even up to a year as long as it has access to a host, such as a pet or human. Even without a host to feed on, fleas can survive for weeks. Because of their rapid reproduction and resilience, it's best to tackle a flea problem as soon as possible. Hiring an exterminator is recommended to prevent the infestation from worsening.

While it may cost more to hire an exterminator than trying to treat the problem yourself, a professional is worth hiring if you have a major infestation. If the problem is severe and the ants are causing damage to your home, then DIY methods may not be as effective as a professional treatment. Plus, if you have carpenter or fire ants it’s best not to risk the damage they can cause to your home.

Foxes can catch rabies. However, it is rare, and even rarer for them to pass this disease on to humans. If you do see a fox in your vicinity acting strangely, disorientated, having seizures, or randomly trying to bite, contact your local animal control, police, or Department of Environmental Control. And if you are scratched or bitten by an animal you suspect has rabies, seek medical treatment immediately.
