How long can a cockroach live without food or water?

Did cockroaches coexist with dinosaurs?
Absolutely! These resilient creatures have been around for quite a while.
It’s estimated that cockroaches have been scurrying the Earth for at least 200 million years.
Considering we have roach fossils from about 350 million years ago, they even walked (or rather, scuttled) before some dinosaurs.
Can cockroaches worsen my allergies?
Sadly, this is true.
Cockroaches release certain proteins that might trigger sensitivities, especially in individuals with asthma.
Moreover, their droppings, decaying molted skins, and the bacteria they carry can further exacerbate allergies and even lead to diseases if they come into contact with food or common household surfaces.
Do cockroaches really eat anything in sight?
They sure do have a diverse diet.
Cockroaches aren’t picky eaters – they’ll munch on plants, our food, shed skin cells, trash, and, a bit unpleasantly, even feces.
Is it true that cockroaches like beer?
Some might joke that roaches are just trying to enjoy a cold one, but in reality, certain roaches are attracted to alcoholic beverages like beer.
The likely culprits are the sugars in the drink, rather than a penchant for partying.
Is there any place on Earth where you won’t find a cockroach?
If you’re looking to live in a roach-free zone, pack your bags for Antarctica.
