When temperatures exceed 85 degrees, that's when we typically see flying cockroaches, with some species actually gliding rather than flying. In extreme heat, cockroaches usually seek out cooler spaces because higher temperatures cause them to use up more energy.
There are several species capable of flying short distances and a number of species — including American cockroaches — that use their wings to glide from high elevations to lower surfaces. Wood cockroaches and smoky brown cockroaches are both strong flyers. Australian, Asian and Cuban cockroaches are also capable of flight, but none of these could truly be labeled "flying cockroaches. One of the reasons that you don't see many flying cockroaches is because of their size. For insects, cockroaches are relatively large creatures.
Their large body mass and flight wings are not conducive to speed or maneuverability. A large, slow-flying insect is easy prey for birds or bats. So even though some cockroaches can glide, they still use their highly effective legs for running most of the time.
In fact, cockroaches are some of the fastest running insects, capable of covering several feet in a few seconds. At 50 body lengths per second , the American cockroach is about three times the speed of a cheetah. Cheetahs, the fastest land mammals, only cover about 18 body lengths in the same amount of time.
If you think flying cockroaches are flying right toward you, they actually aren't. Most cockroach species aren't good "flyers," and what you take as them flying toward you is actually just them being startled and gliding uncontrollably in a certain direction.
Some cockroach species are also attracted to light, and there could be light or brightness behind you or around you that's causing the cockroach to glide toward you. Flying cockroaches aren't necessarily dangerous when they're gliding toward you.
However, cockroaches themselves can be dangerous. They generally don't bite or cause any kind of direct harm to you, but they can contaminate anything they touch or walk across, potentially spreading E.
Coli and salmonella. Cockroaches, including dead cockroaches and cockroach parts, have also been known to trigger allergic reactions and asthma in some people. When disturbed, adult males will take flight. Where they hide: These roaches prefer warm, dry spaces, such as on the upper walls of cabinets and inside pantries, closets, and dressers.
They prefer to stay far away from water sources. Control tips: Place sticky traps where you suspect these cockroaches are hiding, such as near a wall or in the corner of the floor, shelf, or drawer. You also can treat the areas with baits containing hydramethylnon , fipronil, sulfluramid, boric acid, or abamectin. Target areas where the traps have collected cockroaches. Wood cockroaches are about an inch long, chestnut brown, flat, oval-shaped, and have long antennae, tan wings, and spiny legs.
Females have short wings and rarely come indoors. These roaches enter homes after coming to the porch light and crawling under the door. Where they hide: Wood roaches live outdoors in moist, woody areas such as woodpiles and mulch, or under loose tree bark and decaying logs. Control tips: Since wood cockroaches struggle to live inside, you rarely need treatment within your home. Just remove these cockroaches with a vacuum or dustpan and discard them.
Seal cracks and openings, ensure your door and window screens are in good condition. The Asian cockroach entered the United States in , likely from the port of Tampa. These two cockroach types are practically identical, both in size and color. They are both light brown and have bold dark stripes behind the head. The big difference? Asian cockroaches are strong fliers and can fly as far as feet. Where they hide: Asian cockroaches prefer to live outdoors in moist, shady areas such as leaf piles, mulch, compost, and grass.
When their leaf litter is disturbed, they will take flight. These roaches are attracted to light and may enter the home through openings in doors and windows. Inside the house, these roaches will fly to bright lights like TV screens and lamps. Control tips: Reduce the amount of mulch or plant debris in your landscape.
The back pair of wings remains hidden and protected beneath the front pair until the cockroach takes flight. When preparing to fly, cockroaches lift the front wings to expose the back wings. The insects keep the front wings lifted while flying and move through the air by using the back pair. In contrast to the front pair, the back wings of cockroaches that fly are membranous, thin and clear. Even though many cockroaches can fly, the insects boast highly effective legs and prove more adept at running than flying.
The body of a cockroach features three legs extending from each side of the thorax. Covered with setae and pointy spines, each leg varies in length and fulfills different yet interrelated functions that enable the physical act of running.
With a total of six legs working together to propel the insects forward, cockroaches can cover a distance equal to roughly 50 body lengths in a single second. For a human to run the same distance as 50 of his or her own body lengths in one second, he or she would have to reach a speed of about miles per hour. Cockroaches have been bugging businesses for the entirety of human existence. But you can send pests packing this year by kicking them out the door before they even step inside.
