seems black snakes have took a likeing to mom and dad's house.
momma aint all that happy about it lol.
any kind of repellent i can buy to get em gone?

Nope. It's going to be a food source and habitat problem. Deal with those two issues and the snakes will go away.

that's a big part of my problem warrior.
no rats or mice in the house so i can't figure why the danged black snakes like it there so much.

Chipmunks in the yard, bats in the attic, birds nesting in the shrubbery, it could be anything. It doesn't have to be much either with the slow metabolism of snakes they only have to eat every so often, maybe once a week.
Where are the snakes being found?

Rodents and birds are our most local snakes preferred food sources.Most difficult to eliminate their entire food source. Just because we all live in a diverse habitat. What isnt there that they prefer they find an alternative food source that they must settle for.

Kind of like going to a bar in the evening. You have big plans for finding a pretty, curvy gal but as the clock ticks by no takers it seems. However as the clock gets close to closing time your standards drop a few levels and a few drinks later your previous thought of finding a 10 are now lowered to settling for a 3 -4 or lower. Or worse comes to worse you go home alone or hungry.

Snakes arent much different.

Bob, a friend of mine that played in a band put that whole 'closing time' thing in proper perspective. He said when you wake up with your arm around a gal that is so ugly that you want to chew that arm off, you should have gone home alone and hungry.

Black snakes

i know all about the food and it drawing the snakes, just can't figure out the why cause aint much food there at all.

ding ding a light just came on lol mom has loads of bird feeders outside maybe thats the draw.

Once I eliminate the food draw, I look for habitat. Clutter is a snakes best friend.

Now, I don't mean dirty or nasty. Every body has clutter to a certain degree. It can be something as simple as Christmas decorations stacked up in the corner of a basement. Or maybe boxes of old cloths piled up in the corner. Now. Stack and pile this stuff in a cool dark quiet space with little to no traffic and you have a snake habitat!

I went to a lady's house a couple weeks ago. The place was immaculate! But, down in the basement was lots and lots of things being stored. Much of it was stacked neatly atop of cement blocks to keep it off the damp floor. One spot where there was a space of dirt floor had cement blocks lying flat with boards laid over them to create a floor to store things. This is where I found the snakes bed.

I do sell repellent jobs at times. I put down straight sulfur. Does it work? The jury is still out. But I tell my customers up front that it's not a proven deterrent and then explain the theory behind it. Sulfur, while being fairly harmless, is an irritant. It burns the eyes and nose and taste foul. Supposedly, it gets between the snakes scales as he crawls and irritates. They tend to pay me to treat the premisses for peace of mind.

I also go around and look for travel ways, little holes or big open spots where they can get in and out. If the customer so chooses, they may hire me to plug all these holes.

Since you mentioned the bird feeders, there is your definite draw. Bird feeders will draw birds, mice, squirrels, chipmunks and all sorts of seed eating critters. Snakes are drawn to all of these.

Oh! Here's another thing to consider. Night lights! If there are many night lights that stay on at night, this will draw bugs. Bugs will draw frogs and frogs can draw snakes.

Okay. I'll stop here. That's a lot to think about. Snakes are easy to get rid of. Pack up the clutter, take away their cover, seal their travel ways and remove the food source and your snakes will leave on their own.

Snakes like tall grass. I see them around my house when I don't mow.
