Is this TRUE?

Trying to say this without being dramatic but yeah it's really really important to comb your pigs hair because they can get this thing called blowfly strike, it's when flys lay eggs on the animal's , eyes, ears or nose and basically maggots hatch out eat it's way into the animal and eat it from the inside-out. i don't say this to scare you i just want it to be known because to be honest i think this is one of the worst ways to die. This infection can often be miss read and can cause unnecessary worry BUT if you see any maggots on any part of your pig's body then take them off and rush them to the vets immediately if action is not taken quickly then im afraid your pet will most likely die within 24 hours.
