It’s usually just one or two at a time.
And I wouldn’t worry about it unless you start waking yourself up at night digging at the inside of your ear.
You’re making my ear itch and now I hate you! 
Oh, stop! You’re being overly reactionary, gonzo! You know as well as I do that they prefer soft, warm, moist skin. Earwax repels them.
We use to see those occasionally on pet cats. It is a real skill to be able to reach in the hole and pull those suckers out with forceps.
Round here they are called “wolves” or “woofs” by the locals.
Hard to tell thus far. 
Mmm… grubby.
What an interesting place not to be.

If you’re talking about the grass he let them go in, I’d agree. Stay out of there!
Confucious says, “He or she, who plays by the hook… usually ends up with barbs in their fingers.”
(Where’s that ‘over-the-glasses’ mom smilie???)
Gah.

It’s been years since I had a biology class, but if memory serves me right, it’s the adult beetle that lays eggs, not the larva, or grub, right?
That was my understanding.
Oh, c’mon, don’t spoil the fun, especially with the Weekly World News going out of business and all. . .
I’ll take “The Bloody Obvious” for $2,000, Alex.
You guys are letting facts stand in the way of a good story.
Party Poopers. 
Reality is stranger than anything the nuts on this board can come up with. Actually, those holes are left by bot fly larvae in the genus Cuterebra when they emerge from the warbles, bumps are caused by them living under the skin. Some entomologists when they find animals with warbles will take good care of the animal in hopes of getting a good specimen of the adult bot fly. I was crestfallen when a veterinarian friend mentioned she had gotten hold of a rescue ferret and hadn’t reared the bot fly from the warble on the ferret. She dismissed it as a case of the disease cuterebra that had to be treated. That could have been a remarkably valuable specimen to science!
In the tropics, there is even a bot fly in the genus Dermatobia that infects humans. One of a group of entomologists in its range developed a warble. He tried to take good care of the larva in his arm so he could have the honor of rearing a rare and unusual specimen. It emerged from the warble to pupate, but died before it could do so. It was put in the traditional insect specimen collectors’ match box and given a memorial service fit for a head of state by the entomologists before being placed in a jar of alcohol to preserve it properly. The story made perfect sense to me, but I think you would have to be an entomologist to truly understand.
