Carpet beetles do not bite humans, but their larvae can cause skin irritation that’s often mistaken for bites. These tiny, bristly larvae have barbed hairs that can lead to allergic reactions in sensitive individuals, resulting in red, itchy welts or rashes. While the irritation may resemble bug bites, it’s actually a response to contact with the hairs or shed skins, not an actual bite. Adult carpet beetles are harmless and primarily feed on pollen, but their larvae can damage natural fibers like wool, fur, or leather in carpets, clothing, and upholstery.

The most effective natural roach repellent is Borax with its key ingredient of boric acid and diatomaceous earth. But some homeowners may not feel like these are “natural” enough, especially since you can’t use Borax around curious pets or toddlers.

On the other hand, studies have shown that oregano oil mixtures have some of the best repellent effects, and other research indicates that catnip oil, peppermint oil, and citrus oils have notable effects on keeping roaches away. Rosemary oil has been shown to be the most effective natural oil for killing cockroaches outright.

Termites are very hard to remove, especially if you don’t work with a professional pest control service or keep up with routine treatments. Queen termites can lay up to thousands of eggs per day, meaning these pests can spread quickly. You may need to combine DIY treatments and professional extermination services to get rid of a termite infestation.

Bleach can technically kill drain flies, but it’s not really a great tool for getting rid of an infestation. Bleach flows down your pipes too quickly to penetrate the film where drain flies lay their eggs. Alternatively, you can use it to clean around drains, which can help prevent drain flies from returning once you get rid of the infestation.
