You can't use ivomec paste because it is only 1.87% ivermectin. The ivermectin you are supposed to use is the injectable kind bought at the vet. You may be able to find it at a Tractor Supply store or other livestock store. The paste isn't going to do A THING.

PLus, if you got the paste, it better not have any other dewormers with it. Alot of that stuff is only meant for mammals and may not have been tested on reptiles. Therefore, you could end up with a big allergic reaction to it which equals a dead snake.

Injectable ivermectin has been tested on pretty much everything and is safe to use. I still don't see how that paste dissolved in the water...
