As I'm french (sorry! ) I don't know what you're calling tapeworms.
Telmin KH is killing some specific kinds of ascarids and tenias. Price of the 10 pills box is around $8, here in France. As balls are not too heavy snakes and deworming should not be done too often (once every 3 months?) one single box provides you what you need for quite a long time...
As often as possible I try to avoid "hard injections" with needles or force feeding.
I'm using Flagyl and Telmin under the pill form. I break the pills in little pieces, and calculate the appropriate size depending of the weight of the snake.
I use Panacur under the powder form and here also calculate the amount of powder needed.
With dead prey put the little pieces of pills in one hear of the prey before giving it to the snake. Funny way, indeed, but it works pretty fine without any stress for the snake, and obviously for the prey, as it's a dead one!
With live preys carefully open the mouth of the snake.
A tip for that? While holding him behind the head tickle the nose gently with a pen for a while and he will wide open his mouth himself. At that point put the pen between his jaws. Drop inside the mouth, just before the pen, the pieces of pills (make sure that they're not going inside the hole of the trachea!) and then move the pen before them. Push gently the pen to the back and pieces of pills are going at the begining of the throat without stressing too much the animal. Retire the pen, wait for a few minutes, feed with a little mouse, and all that (mice and pieces of pills) goes right into the stomach!
Regarding the powder wet half of the fur of the prey and give it like that to the snake. When the prey is half ingested drop the powder on the wet part of the fur. It stays on, like glued, and the snake is eating it without even notice the product.
