"These are bugs that have had some horrible impact on human affairs. These are not good bugs; these are not bugs we love. These are bugs we fear and hate," Stewart said.
The book features the scorpion, the black widow and even the bark beetle. One of the most harmful bugs in her book is also one of the smallest.
"On a catastrophic, human scale, the mosquito is the world's worst horror story. It's killed more humans through malaria than all other bugs combined," Stewart said.
"Wicked Bugs" is the sequel to Stewart's "Wicked Plants," which was a New York Times bestseller. Both books tell dark, tragic stories. But, she aims to educate people, rather than frighten them.
" Most bugs are very benign and very safe. But there are some that it is a good idea to get educated about. So if you're going to be afraid, just be a little more accurate with your fears," Stewart said.
Stewart will be at the Botanic Gardens on April 21. She will be speaking about plants and bugs at 7 p.m.
