This is the 3rd snake i have caught in approx. 3 weeks time. The first one was the 1st week of june, i was sitting out side enjoyinh the calm night. I felt something crawling up my foot and leg and i jumped up and shined the flashlight (the flashlight stays glued to me when i am outside at night because of the huge population of spiders that populate my yard) and the 3 ft. snake was black and had poorly shaped greyish rings going down his body. It curled up and snapping at me. How could i let this potentialy deadly snake get away?
I have a soon to be 4yr old and soon to be 2yr old that play in the yard, so i completely ignored the fact that you should not attempt to catch these snakes; i want it gone! So i grabbed some “picker-upers” and captured the snake to find out more about this one later. I put it in a plastic container with a heavey piece of glass i been saving for a rainey day, and sat back down. 10 minutes later i heard a plump behind me. I jumped up once again and shined the light. Another snake of the same kind! i thought for sure it just escaped my container. so i grabbed it again and took it to the container and found that it had not escaped, i have captured 2 of these snakes in 10 minutes time. Still have no idea what kind they were, i only know that they are the dead kind now.
Now today i was walking aroung my utility trailer and a glimpse of yellow movement caught my eye. I look instantly and discover this black 2 1/2 ft. snake with yellow stripes running the length of its body. I stepped closer to make sure i wasnt seeing a mirage or something. It jumped at me and snapped wide mouthed, extremely fast. That made me mad. I darted across the yard (most of my momentum camed from when i jumped back startled the thing charged at me) and snatched my handy “picker-upers” and headed back ready for my last breath-once again, fearing for my childrens safety. It wiggled heavely and burst a disgusting amount of some form of liquid. It has 3 stripes that are yellow along its back and a checkered belly.
Is there an agency that helps in the capture of the snakes for removal? I wander if i should invest in some more gear for what may be lurking next?

Luckily we only have one poisonous kind, that I know of, in Michigan and it is shy and not seen much. I don’t know what I would do if I encountered the snakes pictured in your post. I expect it would involve screaming and running.
