Dealing with Black Snakes Around Your Home or Garden

By:

Black snake crawling on ground

We’ve got two black rat snakes living in our barn, and I recently encountered one of them on a morning walk. This is the only time I’ve seen them so boldly out in the open. More often, we get the “periscope,” a little black head popping out of the grassy fence line or under a barn stall to check out what we’re up to.

I don’t know if black snakes are more common in some areas, or if they’re just easy to spot because of their deep black coloring, large size – up to 6 feet long – and their fondness for climbing trees and rafters. Either way, they’re by far the snake most often encountered by people I know; making them the subject of the most screams, “snake dances,” and unfortunately, the most snake killings.

About Black Rat Snakes and Black Racers

If you’ve got black snakes around your house, chances are they’re either black rat snakes or black racers. Both are nonvenomous black colored snakes with white or grayish bellies that eat mostly rodents and other small animals, and neither are out to hurt you. They’re only around because there’s food nearby, and that food isn’t you.

  • Black Rat Snakes: These snakes are fairly slow moving, and often freeze when confronted. If they get really upset, they might rattle their tail in the leaves as a warning. Some rat snakes are laid back, but others will strike if handled, so it’s best not to mess with them.
  • Black Racers: Black racers, on the other hand, are much faster-moving and prefer escape over conversation. They’re more likely to panic, flail around, and bite if disturbed.

Facts About Black Snakes

  • Diet: Black snakes mostly eat rodents, lizards, birds, and bird eggs. Rat snakes are constrictors while black racers generally aren’t. They can climb trees; and, if you don’t protect your bird houses with baffles, will break your heart by invading the nests.
  • Smell: Rat snakes emit a musky smell when threatened.
  • Habitat: Black snakes live in grasses, forests, marshes, and buildings. Wherever there’s food and dark shelter, there might be black snakes.
  • Benefits: Black snakes eat large quantities of rodents. If you can get over your fears, they’re good to have around your garage or barn to keep the mice at bay.

Common Black Snake Myths

Myth #1: Black snakes keep poisonous snakes away.

Having a black snake doesn’t guarantee that there are no other snakes around. Black racers do occasionally kill and eat other snakes. Black rat snakes, however, aren’t known for snake killing. In fact, they sometimes will even hibernate with other species of snakes, including copperheads and rattlesnakes.

Myth #2: Black snakes mate with copperheads.

There’s a common myth that black snakes have interbred with copperheads to create a venomous black snake. That’s not true. Baby black snakes have colored markings that are easily mistaken for copperhead markings; but as they grow, those markings fade to black.

Myth #3: Black snakes are completely harmless.

Just because I think black snakes are good to have around doesn’t mean I want to be bitten by one, any more than I’d want to be bitten by a raccoon, a rat, or a stray dog. Any snake bite – even a nonvenomous one – is likely to be painful and full of bacteria which can lead to infection. So it’s best to treat all snakes respectfully, keep your distance, and avoid being bitten.

    We came a black snake stretched across our gravel drive basking in the sun. As we approached it took off, climbing into the brake portion of our tractor wheel. Poked at it a bit to remove him. It eventually came out but kept trying to go back under the tractor. It was eventually convinced to ‘move on and out’.It then climbed a nearby tree and INTO the bluebird nesting box! Yikes, hope the bluebirds were done nesting for the season. Now, off to build a baffle of some sort to deter further hibernation/sleep overs in there!

    Black racer snakes are the most scariest snakes from the family of Florida’s snakes. Yes, they’re non venomous. But their speed and their ability to swallow their preys alive make them rank the top of my “Don’t-Want-to-See-in-Person” list. Source: floridasnakes.net

    Just came up stairs from the ground level of my house (garage, den, laundry room) turned a corner to find a black snake in my hallway. I screamed a lot and let my husband dispatch the snake. How/is, there a way to make sure this does’nt happen again? I don’t think my heart can take it.
    I assume it came in through the basement door and climbed the carpeted stairs and into the hallway because my husband sometimes leaves the door open. He will not take the blame. I’m trying not to have bad thoughts. Any way to keep them away from the house is appreciated. We live in the suburbs of W-S.

    Last weekend I found a black colored snake with faded brown diamonds in its skin. The belly was silver with yellow spots near the head underneath. He was slow moving and froze when I was checking it out. It was like he was checking me out. I thought it was a Rat snake. Two days later my cat found a smaller one on my back porch so my husband kille it. Today I found that bigger snake again in the barn in a food bucket so I killed it. My horses have been kicking the stalls at night so I figured it was scaring them. I hated to have to do that.

    Today my wife spotted 3 foot black snake curled around her favorite front flower pot. This is a large pot with lots of flowers. He was very comfortable and didn’t want to leave and for some reason he/she was excavating one of the flowers. I turned the hose on and got him to move, but not very far. Now my wife is not happy with the situation. We are in a wooded are and the front has a series of shrubs that cover the foundation. My wife was all set to trim them, but now that job is falling to me. Is there any polite way to find a new neighborhood?

    When I came home there was a black snake in front of my garage. When I opened my garage to try and run over it I noticed there was another one already in my garage. I called for help and my neighbors can. All and all there was 3 of them. By the time Animal Control came two had gotten away and they caught one. I understand about the bit however I still do not want them at my house.

    This week we found a 5-6′ Black Rat Snake in our front yard removed it, 2 days later it was back on our rock patio. My husband took it about 100 yds away and it was back same area within a few hours… TODAY… my husband found the snake in our hallway of our home!!! We gave it 3 chances and sorry but not sorry it was killed today.. I am freaked out to say the least… We have 3 kids and small dog and I can’t for the life of me figure out why it kept coming back till it was inside my home.. We live in North Georgia Can anyone shed some light on this and should I expect to see more??? like babies???

    We live in the metro Atlanta area (Stone Mountain side), and my husband returned from library today to see find shedded skin in the drive way. Something made him look further and he found a black rat snake (assume this is what it was), which was approx. 3′ long, in our garage. It took awhile, but he managed to kill it with a shovel. What are the chances there are more? I do know if it had been in my garage long or just happened to go in today as I accidentally left it open (approx. 1 hour). Told husband that I wanted the garage cleaned out immediately so that I can see the floor. Thanks.

    Seems like we have more mice …and more snakes this year. I discovered a snake skin in our basement and found a live black rat snake in our garage yesterday. Is there any reason to remove him? He’s about 3 ft long and hides under our stairs. Frankly, I’d rather have a snake than mice but am mildly freaked out at the thought of it! Any suggestions?

    I have a black snake that keeps popping up around my house. I have railroad ties and there are lizards and frogs there, so I’m sure that’s what’s keeping it (them) around. It has stayed away for a while, because I worked out in the yard a couple of days and kept running it off. So far, it’s been pretty respectful, to take off and stay away if we’re out. But yesterday I saw it in my backyard, slivering very quickly along side my house and down the bank. A little too close for comfort. I have two little dogs that go out the doggie door, and wouldn’t want them to walk up on it.

  21. Charlotte Says:
    July 15th, 2013 at 6:26 am

    Like June, We also have railroad ties – most of them are rotting and we’ve begun to remove and replace them with 6X6 pressure-treated lumber…a slow process. Living on a mountain side, the original owners of the home piled rocks on top of the ties which only adds to the issue. Lizards, spiders, toads, etc., love to live there. I’m trying to be mindful and considerate of nature. In the meantime, I’m making sure there’s no “easy access” into our home. My husband found a rather generous hole in our foundation where the AC pipes go in – I’m sure mice and snakes have used it in the past – it’s now filled!

  22. Paul Halagan Says:
    July 17th, 2013 at 6:32 am

    Our black snake continues to be spotted in the yard, but not the chipmunks. We had quite a colony last year, but I’ve only spotted one this year. So I figure the snake is earning his keep for now.

    OK on July 4th I had a black snake about 5-6ft long on my front porch.. Today august 31st I was in my basement tanning and when I went to go up the steps there was a little black snake about 5-6 inches long.. I’m scared to death of snakes and always have been. I use to have nightmares about snakes when I was little. My husband killed the baby snake and I am just wondering if there is more in the basement? Does snakes lay the eggs and just leave? And if there is one baby snake in basement is there usually more.. Some one please help me.. I am ready to Move out..

  26. Charlotte Says:
    September 2nd, 2013 at 9:54 pm

    Candi – get a grip. Black snakes are just as afraid of you as you are of them. Find out how they’re getting in and fix the problem. In the meantime, you can look forward to fewer mice.

    This evening, while walking my dog, I saw a black snake stretched out, hanging upside down on a tree. It looked to be about 5.5 feet long. I ran into the house to get my camera and when I returned, it was gone. I didn’t know snakes could climb. I’ll be looking up, from now on.

    If you want to try to keep snakes away from your HOME there are granules which you can purchase at your local Feed store or for that matter, WalMart, etc. Also, most snakes abhor sulfur so you can use that around the perimeter of your home. Of course, both methods are NOT rainproof, so, you will have to bear that in mind.

    p.s. The title says “Dealing With Black Snakes…etc” yet the author does not mention ANY methods at all TO deal with them. The title leads one to believe that there will be information provided to keep them at bay, so, how about putting some information in the article which will do just that. After all, the title is misleading otherwise.

    Thanks.

    Thanks for pointing that out Gary. I, too, was hoping to get some advice rather than stories about “sightings.” Having recently spotted a copperhead slithering past our patio door, I’m more concerned about their presence. We have a new puppy so I’d rather keep them away from the house and will be sure to read the label to see about pet safety. Thanks again for sharing your knowledge.

    I recently went to my 3rd story attic for holiday decorations and found black snake skin shedded in various areas; also, rat droppings! Is this snake likely to live there during the winter to eat the rodents, or is the snake hibernating outside?

    Oh my goodness. I found baby snakes obviously just born in a drawer in my house in a room I hardly go in. My uncle took them out and got rid of them. There was a hole by my water heater. I moved out the babies where brown and black. A few days before I found the babies, I heard what I thought was amice running along the top of my wall and drop the floor in my hall. I was too afraid to look but I think it was the momma snake. There is both woods and a pond in behind my home and my uncle complained of water moccasins while fishing, I never went back. I just think they made my house a home.

    we have taken in a stray cat that is unfortunately declawed (both front and back). The cat likes to hid under our shed which is where some black snakes like to hang out. very large black snakes! Do I need to be worried with the snake hurting our cat since it is declawed?

  35. Charlotte Says:
    May 14th, 2014 at 6:57 am

    My experience is that black snakes are very shy and retiring. They only bite when harassed or placed in a defensive situation. If you cat has any sense at all, she will know to retreat if she runs into the snake. We’ve de-clawed cats but never front and back. Leaving the back claws in place allows them to climb and scratch to defend themselves. You might want to reconsider allowing her to go outside. I know there might be extenuating circumstances but if there’s any way to make it work, she should come in.

    RE: Snakes in the house – we had a small hole in our foundation where the wires come in from the AC compressors. The mice were coming in through the hole. The snakes were coming in after the mice! Shortly after removing their food source and plugging the hole and trapping the snake, the problem disappeared. So check for holes!

    I keep hearing a dragging sound at night in the ceiling over my bed in my bed room so it’s hard for me to sleep knowing that something is up there, lately it moves when I am asleep and the house is quiet so I get up and retreat to another room, I called a few pests control companys but they say that it’s not a snake because snakes do not make noise this thing is moving on the top of insulation, what can I do becaus I am not sleeping at all.

    My husband has killed two very lengthy black snakes in our back yard, one got away a couple of times but came back over and over and finally he was able to kill him, and then he killed another just a few days afterward, and now today we saw another one in the back yard in which crawled back into the wood before my husband could get to him, what is making these snakes come into our yard this year, we have been here for about 9 years and have never seen anything like this ?

  41. Charlotte Says:
    June 23rd, 2014 at 7:59 am

    Someone once told me that, like most wildlife, snakes follow the food. If you’ve seen an increase in mice, they may be after them. If you have moles or voles, same thing. Last year we had a ton of tunnels from moles in our yard and saw an unusually large number of snakes. This year, with the new addition of two large-breed puppies (who unfortunately like to dig), the moles seem to have vacated and to date, we haven’t seen a snake. Of course, I’m sure we will.
    It saddens me to read about many readers who are trying to and succeeding in killing black snakes. Of course, there are extenuating circumstances, but in general, they are the good guys – eating insects and all sorts of other vermin. They’re actually quite shy and don’t really want to have any thing to do with you. I hope you’ll all do some reading about them and think twice before attempting to kill one.

    I live in a condo in SW Florida and this morning I watched in shock as one of my cats chased a small black snake that slithered under my bed! It moved so fast. I have no idea where it is now, but don’t feel very comfortable about the prospect of sleeping with it in the house. I doubt that I can afford a professional to come out, find and remove it. How long can it live without food? Any recommendations?

    3 days ago, I saw a black snake crawling behind the dry wall in my garage. We have left both doors open to the garage for the last 3 nights, but he seems to either not leave, or keep returning. Do they find a home they like and stay there? I don’t mind him in the yard, but rather he leave the garage.

  51. Charlotte Says:
    September 1st, 2014 at 7:51 am

    My guess is that you may have mice or some other snake “food” living in your garage. That was our situation – we got rid of the mice and the snake went elsewhere. A word of caution – “snappy” traps seem to work the best. I would avoid poison, especially if you have a dog or cat.

    Yesterday I was working in the basement making a path for a new dryer to be delivered through the bilco door. I had the bilco door open for about 2 hours and when closing it for the night I found a black rat snake on the 2nd step. I closed the bilco door for the night and trapped the snake in the stairway area between the regular door and the bilco door. This morning I found the snake coiled up and resting quietly on to top edge. I gently picked it up about half way back and dropped it in a laundry mesh bag. The snake was released in the shed about 50 yards away. He/she was docile and not aggressive at all. If I see it back near the house I will release across the river, about 2 miles away.
