In 2018, a cockroach crawled inside a sleeping man's ear

Luckily, roaches don't go out of their way to do this,

But there are a bunch of other unsavory bugs

that will lay eggs all over your body on purpose.

These insects, which are native to Central

and South America, glue their eggs to mosquitoes

When the mosquito bites you, the eggs hatch.

creating a painful pimple that leaks pus.

Not long after that, they reach adulthood,

ready to mate, and start the cycle all over.

Another tropical parasite is Tunga penetrans,

Females burrow into the bottom of your foot

They start off smaller than a grain of sand

but grow to 2,000 times their size within a week

as they swell with your blood and up to 200 eggs.

waiting for the next bare foot to pass by.

But some egg-laying parasites go more than just skin deep.

Tapeworms, for example, invade your intestines.

Adults can grow to be longer than a bowling lane

because they lay tens of thousands of eggs,

If that sounds gruesome, just wait till you hear

When the flies bite you, the larvae enter through the wound.

After five months growing beneath your skin,

they reach adulthood and start to release

moving under your skin or across your eyeball.

But, hey, not every egg-laying invader is sinister.

Face mites, for example, are pretty innocuous.

They live on pretty much everyone's face,

After all, they feed on facial oil, not flesh.

females just lay one egg inside of your pores.

Even better, researchers can now study your face mites

to track how your ancestors migrated across the planet,

because we usually pass them from parent to child,

But face mites aren't the only helpful bug around.

Green bottle flies might be useful in medicine.

They lay their eggs inside of open wounds,

and then the maggots hatch and devour the damaged flesh.

They even secrete proteins that reduce inflammation.
