A California woman’s home became a very bad nightmare when dozens of rattlesnakes were found underneath her house. (AHHHHHHHHHHH)

The woman called Sonoma County Reptile Rescue on Oct. 2 after suspecting snakes were living under her home in Santa Rosa, California.

Al Wolf, the director of Sonoma County Reptile Rescue, responded the following day to retrieve the snakes. Wolf looked underneath the house where he found dozens of rattle snakes. He said that later he found baby snakes, too.

Wolf said, The snakes were Northern Pacific Rattlers, which are considered one of the most deadly snakes in Northern California.

It took almost four hours to retrieve the first 22 adult snakes and 59 babies in the den. Wolf made another two trips to the site and found another 11 snakes.

The Santa Rosa homeowner, meanwhile, said she doesn’t want to be identified because she doesn’t want neighbors to panic.
