True, but in the same way wasps and hornets are not poisonous. They can put one heck of an OUCH on you.
We have then here too. I took my grandchildren out one night with a portable UV light so they could see how they glow under the UV light.
Doesn't take too long to find them around tree bark, old logs etc. When you start to picture them as "land shrimp",
("Ummmmm! land shrimp!")
it's time to go back to the house and pig out.
