Overview
Written for the homeowner,
not the industry.
Most information about bats online is either dumbed-down, wrong, or written by companies trying to close a sale. Sam wrote this book to be the opposite: honest, specific, Michigan-focused, and genuinely useful whether you hire him or not.
Across ten chapters, the book walks you from the first sign of a bat in your home through Michigan’s exclusion laws, entry-point identification, the humane removal process, long-term prevention, and how to vet a wildlife company. It reads like a conversation with the most experienced person in the field — because it is.
“I wanted my clients to be able to make an educated decision before they ever call me. This is the book I wish existed when I was twelve years old learning the trade.”— Samuel Sullivan

What readers say
Homeowners, inspectors,
and one very informed skeptic.
“I read this cover to cover in one evening. By the next morning I knew exactly what questions to ask the three companies I'd called for quotes. Two of them couldn't answer them. Sam got the job.”

“Every homeowner in Michigan should have a copy of this. Clear, honest, no scare tactics. It reads like advice from a friend who happens to be the top guy in the field.”
David T.

“I've been a home inspector for eighteen years and I still learned something. The section on entry-point identification is genuinely excellent.”
Michael R.
Home Inspector · Oakland County
“The chapter on Michigan law alone is worth the download. I had no idea about the maternity season restriction. This book probably saved us thousands.”

About the author
Samuel Sullivan.
Michigan’s Bat Expert.
Sam is a second-generation Michigan wildlife specialist and founder of Michigan’s Bat Expert. He apprenticed under his uncle — one of the earliest humane wildlife practitioners in the state — starting at age twelve. Today the practice represents more than 30 years of combined family experience in Oakland County and surrounding areas.
He chose to specialize almost exclusively in bat exclusion because it is the most regulated, technical, and misunderstood corner of the industry. He wrote this book because homeowners deserve better information than what the industry usually gives them.
