Best pest control specialists near Sharptown, MD

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.

There is no exact science here, due to the nature of nests and how mice raise their young, but a good place to start is to inspect the droppings. A single mouse poops a lot, leaving around 50 droppings in a single day, likely near a primary food source. If you find only sporadic droppings, you likely have a small infestation. If you spot large mounds of droppings, you are dealing with a big problem.

Rats are nocturnal creatures, meaning they are most active at night, typically from late evening through the early morning. They use the cover of darkness to explore, forage for food, and find water, as they feel safer and can avoid daytime predators and human activity. Their sharp senses, including keen night vision and hearing, are well-suited for navigating in the dark. Because they prefer to stay hidden during the day in secluded areas like walls or attics, you are more likely to spot signs of their presence—such as droppings or gnaw marks—before you see an actual rat.

The full process of using a rat exterminator can take several weeks. If you have a larger infestation, the exterminator may need to return several times to collect rats. The timeline of your rat eradication depends on the infestation size and type of treatment, so consult a rat exterminator to get an accurate estimate for your specific issue.
