Have you ever seen a cockroach in a high place and wondered how it got there? Can they climb? Learn more about the anatomy that allows different species of cockroaches the ability to climb better than others.

Climbing Cockroaches

Cockroaches can climb. When you encounter cockroaches, you're not only likely to find them scampering across the floor or a countertop but also possibly climbing a wall or crawling across a ceiling. The “foot” at the end of some cockroaches’ six legs resembles a claw. This is called a “tarsus.” At the end of the tarsus is the pretarsus, which are essentially toes. These claws and pad-like structure are what allows the cockroaches to climb and walk across the ceilings.

Surfaces Cockroaches Can Climb

Unfortunately, many of the materials used in home construction — wood, drywall, brick and stone — offer cockroaches plenty of gripping surfaces, enabling them to climb vertically and walk upside down on a ceiling.

Surfaces Cockroaches Cannot Climb

There are some surfaces in our homes that are usually too smooth for cockroaches to climb. These include:

Porcelain Glass Smooth metal Granite Marble surfaces

Rapid Inversion

Rapid inversion refers to cockroaches’ ability to swing their bodies from the top of a surface to its underside in a split second. A cockroach will run rapidly toward the edge of a surface until most of its body clears the edge. At the last moment, the rear legs grip the edge and the cockroach swings its body around to grip the underside of the surface. This article explains how different animals, including cockroaches, perform rapid inversion. You can also checkout this video from the University of California, Berkely. Very few people are excited about discovering cockroaches in their homes. Cockroaches can be mechanical vectors for salmonella and E. coli, as well as trigger allergies and asthma in some people. They also secrete an oily substance with a sickening odor, which can affix itself to dishes, food and clothes. It’s pretty clear that cockroaches are very adaptable creatures on earth, surviving and multiplying on tiny amounts of food and moisture virtually everywhere. If you’re dealing with a roach problem, contact Terminix® and let our trained technicians help you combat these pesky invaders.

What are the little black bugs in pasta?

Flour bugs — also called pantry weevils, rice bugs, wheat bugs, or flour worms — are actually tiny beetles that feed on the dry food in your pantry. Flour, cereal, rice, cake mixes, and pasta are all favorites of these miniscule foodies.

grove.co - Are Flour Bugs Harmful? 6 Natural Tips to Keep them Out!

Whether you’ve already got ‘em or you’re trying to avoid ‘em in the first place, we’ve got six hot tips for flour bug prevention.

Six natural tips to keep flour bugs away:

1. Deep clean

Remove everything from your pantry, and toss any open containers and items that have been infested. Vacuum the shelves, then use an all-purpose pest remedy spray, hot soapy water, or a natural cleaning spray to give it all a good wipe-down before replacing your salvaged dry food.

2. Use proper containers

Storing your flour, sugar, cereals, and other grains in proper storage containers helps keep the flour bugs at bay. Choose airtight containers and jars for the best results.

3. Freeze

If your flour hasn’t been taken over by fully-grown bugs, stick it in the freezer for four days. Freezing kills off eggs and larvae, preventing them from turning into a full-blown army. Freezing any dry foods after bringing them home from the market is a good preventative measure to get in the habit of.

4. Use an insecticide.

Non-toxic insecticides are available specifically for pantry bugs. They do emit fumes, so it’s important to keep children and pets away until the odor dissipates.

5. Natural deterrents.

Garlic cloves and bay leaves are natural alternatives to keep the weevils away. Place cloves of garlic and dried bay leaves on your freshly-cleaned shelves to deter these nasty bugs.

6. Call the professionals.

If your flour bug infestation is really bad or you’re not entirely sure it’s weevils that you’re dealing with, call a pest control specialist to come check it out.
