Woman's Home Infested With Praying Mantises From Christmas Tree The holidays brought an unwelcome present for a Virginia woman - more than a hundred praying mantises that had infested her Christmas tree. Molly Kreuze says an egg sack was hidden in the tree's branches hatched, and now the bugs are everywhere, "crawling on the walls, crawling on the ceilings". But Kreuze, who works as a veterinarian, isn't scared - in fact she's trying to round them all up alive and is even feeding them fruit flies. She says she'll eventually give them away to people who use mantises in their gardens to keep away other pests - and says next year she's getting a fake Christmas tree. How would you react if your house was full of mantises? Ever find something unpleasant attached to your Christmas tree?
