Wild Animals/White tipped cylindrical droppings in my garage


Iterator wrote at 2006-07-17 01:29:53
A:Lizard droppings have white tips due to the process of reptile elimination: Both feces and urine exit their body through the same opening, the cloaca. Lizards are very water-efficient, and their urine is quite concentrated. The white tip on the droppings is uric acid crystals.

We have the same here in California and were also puzzled.  

Chris wrote at 2006-07-19 14:07:48
Yep, Lizards or Gecos in your Garage. I live in Houston also and clean this up from time to time.  Microscopic exam of feces shows MANY insect parts and that white tip of the droppings was Uric Acid or other urates ( Mostly Sodium Urate and Ammonium Acid Urate ). Until I brought these droppings into my Laboratory I was setting Mouse traps without results...wasting my time. The droppings were from Gecos.

I just found the same scat in north Georgia. Dropping vary in size up to about 3/4 of an inch.  All have a white solid end that I mistook to be Styrofoam cells at first. The white is not liquid like bird scat.  Most were on a window ledge in the basement, however I found one on a rock in the yard.  I'll try to get good photos tomorrow.

Add Branson, Missouri to the list. I have puzzled over white-tipped skat on a brick ledge on the front of my house. My best guess was it came from a shiny black lizard I have seen several times in that area. Now I need to find out how to discourage lizards.

white tip on scat (droppings) indicates reptile; what you have is probably lizard.  Gecko scat is common in garages (at least in Austin) but is less than 1/2 in long.

Glad someone else has them!  North Carolina 3/4 inch to 1" with white tips at the end.  On my deck outside!  Yikes!  Must be one big lizzard!

add cherokee county in nortyh GA to the list.  The only lizards i have seen, and seen a few, one large one (6-7 inches) is a skink, one of the lizards that are fast ans skinny and have multiple stripes on them.  Found the droppings on a ledge in the garage.  I do still have some creature eating peanut butter out of traps without setting off the trap though.

Add Tuscumbia, Alabama to this mystery until i found this site. I had been thinking Snakes, my wife will be relieved now. We've tried everything to catch the wrong thing maybe we will have some success. They were having Lizard meetings at our back door.

Charlotte NC too - I was petrified, thinking it was rat poo...same thing, white tipped end & when we moved things in the garage, a skink popped up.

I too have this same kind of droppings in my garage and on my front porch at times.  I know I have chipmunks in the nearby wooded area, and voles as well in my yard.  Several lizards are also found from time to time in the yard.  I live in northern VA if that helps any.  I am curious as to what it is from.

I had the same thing in my garage here on the Space Coast of Florida, and I thought the same thing as many of the other posters! I'm glad to find out it's probably just a lizard - that makes sense, since they are everywhere in this area. Thanks for a great page!

Katy, TX (just outside of Houston) must be the lizard capital of the world. We thought we had a terrible mouse/rat problem but now I know its the lizards. Black/brown cylinder about 1/2 inch long with white tip. Had them all over our garage. They were actually covering all of the ledges between the 2x4 studs. I was confused as to why a rodent would jump up there to poo but then I saw some lizards sitting on the ledge by the roof right over the spot with the poo. DING! We actually have an amazing lizard population which means the dropping problem is actually pretty serious. But on the other hand we have a noticeably lower bug population...

Nov wrote at 2010-12-07 01:38:01
This is kind of weird because I have the same thing. White tipped droppings on my Window ledge. I had a space inbetween my AC and i'm kinda confused, seeing how its pretty cold in NYC about (30-50 degrees). And also the fact that, where I see the droppings, its on the second Floor. Is this even possible, that there could be a lizard in a area of NYC thats so highly populated with little to no forest or lakes.

Definitely here is s. Florida......all over the place! And luckily it helps me distinguish between rat and lizard....

Found these in our garage on Oak Island, NC and suspected a snake.  We have our share of the creepy crawlie skinks and anoles noted over the years, but this is the first time the droppings were found. Thanks for all your input here!  Are there any skink-away repellants out there?

Margot Castle wrote at 2012-05-20 18:26:19
You can add the Sierra Foothills to the mysterious scat with a white tip.  I've been assuming it is from the many lizards we have and welcome.  Your response confirmed my guess.  Thank you for the information.  I'll just keep cleaning it up and enjoying watching them.

RoyalRuler wrote at 2012-06-27 18:32:42
We moved to Rancho Cucamonga almost two years ago, I have seen these white tipped dropping each summer, out side and sometimes in places I thought only birds would go.  But Lizards makes sense we have dozens of them.

In sunroom, south Arkansas. Thank goodness not a mouse!  

Todd Love wrote at 2012-09-20 00:18:56
Charlotte, NC  Thought it was snake poop, seemed to big for a lizard. White tipped 3/4" to 1" long. Found it in garage and boxing in attic.  There was quite a bit of it so I couldn't believe a snake would poop that much.  We do have a lot of the little gecko lizards.  I will relax believing it is a lizard and not a snake.

It is indeed, in my garage a Blue tailed skink. I kind of have him box trained. we have a little deal, he takes care of the bugs and I clean up. Its a square plastic food bowl with a mix of sand and cat litter. Like most guys he finds it about 75% of the time.

Ah-ha! This is really good to know. Moved to AZ a year ago from the east coast and have seen what is described here showing up in the garage. Hopefully those invasive little geckos are on insect patrol. ;-)

Laura wrote at 2013-09-03 00:02:58
Norfolk Va here! I am so happy that we don't have rats living under our deck! I've been in this house for 10 years, have always seen the skinks, but this is the first time ever seeing the poo.. I'll sleep much easier knowing there aren't any rodents out back!

DWB wrote at 2013-10-17 18:27:18
Semora, NC Here...we have Blue Tail skinks and Eastern Fence Lizards as well as assorted small (usually) snakes. Have seen the skinks and fence lizards on he porch, along with scat. Also have scat in the storage unit out back; typically 1/2 - 1" black with white tip.

Have them in Cape Coral Florida too. Cute little boogers.

I have this scat in my garage in Nashville, TN. Are we all CERTAIN it isn't a snake? I'm petrified of snakes. I'm not in love with the idea of lizards either:/  At an inch long, how big would the lizard be?! I'm such a whimp...,

El wrote at 2014-07-23 21:28:41
Bradenton, Fl I guessed the answer. So many geckos under my mobile home and lots of white tipped scat on my steps and driveway. Glad to get it confirmed. Thanks

Betty b wrote at 2014-08-13 01:35:02
The one's I find are Ai least 2 inches long. I don't think a lizard can do that much at one time.

Charlotte, NC here and a HUGE TY for all daughter will be so relieved to know it is a lizard and not a snake..she had a venomous copperhead visit her back porch last week and now finding all these drippings, she's been petrified!

You can also add Natchez,MS to the list. I see this on my porch and carport. I was thinking that it was a Mickey Mouse (sounds so much nicer) or chipmunks. Glad to know it is lizards.

I have found what I believe  lizard poop found in Pickens county, SC. We have a lot of blue tailed skinks.

OMG. We've got white tipped poo too in southern Sydney, Australia. An unwelcome find in the house after coming back from holidays.

Queensland, Australia - I have been told that the white tip indicates a carnivorous donator.  Mine is from our house Geckos.

Just found the 1/2 long blackish brown poo with white tip on ledge of screened porch. Ran across this site in search of what type of pest leaves the poop. Glad to know it's not a roach. I don't mind little geckos, but I HATE skinks.  I took pic of it, but don't see the option of adding photo.

So glad to see others from NC post here, especially Charlotte. I was scared to death thinking I had rats in my garage. All the other websites I visited said the scat from lizards were only a quarter to less than one-half inch. I,too, have three quarter to an inch droppings. I freaked out today when I found some in my bedroom walk-in closet. I was so afraid there was a snake in the house. I did have one in the garage a few months ago. Eeeww

Amy wrote at 2016-10-01 02:31:53
High Point, NC too! They are all over my back porch. I was very concerned on what type of critter was doing this. I can handle a lizard!  

Ethel wrote at 2017-03-07 15:53:46
Have same in New Orleans. But it helps if you turn out the light in that area. Bugs are attracted to lights and lizards hang out around lights to eat the bugs. Read on another website that coffee ground and tobacco is toxic to lizards. So I dispose used coffee ground in flower beds around my house. Went from hundreds to only a few.

I can answer questions about wild mammals and other animals, as well as extinct animals and zoos. I am not an expert about every animal species. I can look up information from books and the internet, but can't verify if all the information is true. Please don't ask questions about: 1. Pets. I am not a vet. Please contact a vet if your pet is ill. You may need to spend some money if you want your pet to live. Don't get a pet if you don't know how to look after it and if you can't provide it with the space, food and possible companions that will help it live a healthy life. Don't take animals from the wild, unless they are ill and/or injured and you can protect them until a wildlife charity can help. It is cruel to take animals from their parents, especially if the parents will look for the babies, while putting their other babies at risk. You may be breaking the law by keeping wild animals or you may need a licence to look after some species. Please check with a local wildlife group. 2. Eggs: Please don't remove eggs from nests. The mother birds provide the right temperature for the eggs and won't sit on them if the temperature is warm enough for them to develop naturally. It is illegal to remove eggs of some species and, unless you have an incubator or a broody hen, the egg may not develop. If you are allowed to touch the eggs, you can candle them to see if they are fertile. If theys aren't fertile, they won't hatch. 3. Fights: Please don't ask about fights between different animals. These questions assume that individuals of two species fight each time they meet and that one species will always be victorious over another. This is untrue. There are cases where a live mouse has been fed to a venomous snake, bitten the snake leading to the snake's demise. 4: Diseases: Please ask doctors or other medical experts about diseases that you may catch from animals. I can't advise on how to deal with viruses, bacteria etc.
