Cockroach Facts !! YUCKYY

The world’s largest roach (which lives in South America) is six inches long with a one-foot wingspan.

Roaches By the Numbers

6 — Number of legs on a cockroach

18 — Number of knees on most cockroaches (at least!)

40– Number of minutes cockroaches can hold their breath

75 — Percentage of time that cockroaches spend just resting (how lazy can you get?)

Some female cockroaches mate once and are pregnant for the rest of their lives (bummer).

Better Check Those Cracks in the Wall !

Young cockroaches need only a crack as thin as a dime (about .5mm wide) to crawl into. Adult males can squeeze into a space of 1.6mm or the thickness of a quarter.

Cockroaches can run up to three miles in an hour. (Hey, it’s no marathon, but it’s not bad.)

Male cockroaches transfer sperm to females in a “gift-wrapped” package called a spermatophore. Some males cover the package in a protein-rich wrapping that the female can eat to obtain nutrients to raise her young. Delicious!

Roaches can live without food for a month, but will only survive a week without water.

Most species of roaches live in the tropics. But roaches live all over the world, including the North and South Poles.

Pest cockroaches can withstand temperatures as cold as 32°F (0°C), but will die if the temperature goes much below that. In extremely cold places, however, they survive by moving in with humans. (Hey, quit hogging the covers!)

Cockroaches can climb walls because they are equipped with a set of little claws on their feet designed for that very purpose.

Crushed cockroaches can be applied to a stinging wound to help relieve the pain.

Sniff, sniff…oh, it’s just Uncle Leo. Roaches use their feelers, or antennae, as noses. Their sense of smell is so great, they recognize family and friends by their distinctive odors.

Female roaches attract male roaches by producing pheromones. Pheromones are chemicals that make the female roach smell REALLY good to the male roach.

Some female cockroaches incubate their egg cases in their bodies until they are ready to hatch. These babies stay with their mothers a day or two after they are born.
