About 35 years ago Marshall Hanks ran a small one-man Pest Control service out of Sturgeon Bay, Wisconsin. Many people called and ask "What can there be done about our bat problem?" At the time the most common thing to do (legal at that time) was to fumigate your home and kill them. Hanks understood this to be cruel and pointless stating "the end result was hundreds of dead bats to deal with and all the exterior openings still open, welcoming more bats in the future".
So now he understood the task ahead of him: To find away to allow the bats to leave unharmed yet unable to reenter in any other area around the structure and Guarantee It!
This initiative to solve something is not surprising. His grandfather, also named Marshall Hanks, started the well known "Hankscraft" company that is still in operation today. His grandfather had over 70 pattens.

Over the next couple of months Marshall worked long and hard to develope an "Excluder" that would work 100%. The above picture is showing one of the original models of the Excluder. It was made of hard plastic with short metal fingures that extended beyond the center opening. This would allow the bats to push through but not return. This "Excluder" was short lived because it needed to be more versatile.
Many more styles were made until He designed the "EX100" which is still in use today.

During 1981 the Bat Control was really taking off. Because he could not be everywhere at once he decided to make "Bat Proofing Kits" for the public. This include the Excluders and a brochure on how to bat proof your home. Marshall, his wife, 3 sons and 1 daughter formed an assembly line to carefully package each kit and send it to the customer. Unfortunately this to was short lived. Marshall says "without the homeowners having the knowledge and experience of exactly where to place the "Excluders" and what openings to seal and not seal, the bats would end up right back in." From then on Marshall Hanks knew that in order to solve a job correctly he would have to travel and provide this service.
The picture above is showing his wife Marilyn also son Tim Hanks (now owner/operator of Commercial Bat Control in San Antonio, Texas) and son Andy Hanks (now owner/operator of Wissota Bat Proofing)serving Wisconsin and Minnesota bat problems.

In Marshall's early career of "bat proofing", the bats would enter through his "Excluder" and into a cage. The bats were unharmed and then relocated. Today cages are not used or recommended.
