Q: Do ultrasonic squirrel repellents really work?

• <div><p>According to the <a href="https://icwdm.org/species/rodents/tree-squirrels/tree-squirrel-damage-prevention-and-control-methods/">Internet Center for Wildlife Damage Management</a>, no frightening devices are proven effective for squirrel control. This is likely because the squirrels quickly become habituated to the noises. However, strobe lights show some promise, so motion-activated lighting could be an option worth considering as part of your integrated pest management strategy.</p></div>

Q: What is the best natural roach repellent?

• <div><p>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 &ldquo;natural&rdquo; enough, especially since you can&rsquo;t use Borax around curious pets or toddlers.</p><p>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.</p></div>

Q: Do roaches ever completely go away?

• <div><p>Getting roaches to completely go away will take a lot of effort, and they hardly ever go away on their own. You will likely need a combination of home treatments, like <a href="https://www.angi.com/articles/whats-best-cockroach-killer.htm">roach sprays</a> and traps, and regular visits from an exterminator, to control an infestation. It can take awhile for these treatments to start working, and you&rsquo;ll need to stay on top of replacing old traps and having additional extermination services, plus keeping your home clean and decluttered, to deter roaches.</p></div>

According to the Internet Center for Wildlife Damage Management, no frightening devices are proven effective for squirrel control.

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.
