Makenna Sewell called the police on August 16 to help kill a spider in her Forest Grove, Oregon house.
The teen is wheelchair-bound because she has muscular dystrophy.

She said the spider was a brown recluse and has toxic venom that can be deadly. Her mother had recently been bitten by one.
"It was no quarter-size house spider. It was massive! It was massive. Just seeing a spider that big and knowing what it did to my immune system and me having a compromised immune system and a younger brother, I just knew that it wasn't good and I had to call someone," she told Fox 12 (video below).
After failing to reach her parents, she called the police non-emergency number and told the dispatcher: "'I'm home alone and there is a giant spider on the back of my couch, and I'm talking giant. I've never seen a spider this big and I have no idea what to do."
A police officer arrived and killed the spider with a rolled up newspaper. He reported the spider was about 2 inches in diameter.
