While often associated with filth, cockroaches boast an array of fascinating and surprising facts you might find interesting. Read on for intriguing cockroach trivia and practical tips to keep these unwelcome guests out of your home.

Cockroach Fun Facts

  • The earliest cockroaches are believed to have been around 300 million years ago during the Carboniferous era. They are one of the oldest groups of insects on Earth.

  • Cockroaches can survive without their heads for up to a week. Their open circulatory system and ability to breathe through their body means they don't rely on the head or mouth to breathe. However, they ultimately die of thirst because they can't drink water.

  • Do you ever wonder how a roach stays alive if you put them in water? Cockroaches can hold their breath for 40 minutes and even survive submerged underwater for half an hour. This ability helps them regulate water loss.

  • Clocking in at three miles per hour, cockroaches may seem athletically impressive. However, this speed also means they can quickly spread germs and bacteria throughout a home.

  • One-day-old baby cockroaches, sometimes smaller than a grain of rice, can run almost as fast as their parents. Their speed and elusiveness pose a threat, especially considering their role in transmitting diseases.

  • American cockroaches are attracted to alcohol, especially beer, likely due to the hops and sugar present in the drink. They will also eat almost anything, including sweets, starches, feces, animal protein, grease, and cheeses. They've even been known to eat their own to settle their belly.

  • The world's largest roach, found in South America, measures six inches long with a one-foot wingspan. In comparison, the average cockroaches you are likely to encounter range from ½" to 2" in size.

  • Worldwide, there are over 4,000 different cockroach species. The German cockroach is one of the most common across America, joined by species like the Smokybrown, Asian, Brown-Banded, American, and Oriental cockroaches.

  • Cockroaches can survive without food for a month due to their cold-blooded nature. However, they can only last a week without water, explaining their preference for humid areas.

Tips for Cockroach Control

Whether you're seeking preventive measures or tackling an existing roach infestation, read on for expert-recommended tips to keep these resilient pests at bay. Below are actionable advice and insights to regain control of your living spaces and ensure a cockroach-free environment.

  • Properly secure and store food in airtight containers, especially in the kitchen

  • Routinely clean to reduce the accumulation of crumbs and trash, especially behind appliances

  • Identify and seal all cracks and holes in your home, including around entry points for utilities and pipes, as these can serve as access points for pests. Cockroaches can squeeze through openings as small as a quarter of their body height by flattening their flexible exoskeletons and moving their legs to the side. If you can slide a small coin or credit card into a crack, an adult roach can probably fit in it!

  • Keep all vegetation, including leaves, pine straw, mulch, bushes, and trees, at least 1 foot away from the perimeter of your home. Roaches thrive in damp environments, and keeping plants away from your walls helps keep roaches further away, too.

  • Maintain adequate ventilation and dry conditions in basements and crawl spaces. If you need professional help, reach out to the Palmetto Exterminator experts for recommendations or assistance in getting rid of unwanted pests.
