So, that makes sense now. I would assume that, since the dose is one tablet, this mix is pretty safe--or the company wouldn't still be in business. I'm shaking my head though over the thought of putting a pill down every chicken....maybe someone better at it than me.

I use lots of 7 dust on the floor of my coop and broom it into the cracks and crevices as well as in the nesting boxes. then I additionally add some diatomaceous earth to the nesting boxes as well. In six years I've never had mites. Of course I put wood shavings on top of it and the one thing I changed once I started this practice was to not throw scratch on the floor anymore. I used to want thenm to turn over the flooring, aerate it, etc. but not now and the poison does not effect them. As for worms, I use the same medicine on my chickens as I use on my dog for heartworms. I buy it at my feed store. it is not made specifically for chickens but for pigs.You just go by weight. You can get injectible or topical. I use the yopical and put several drops on their backs once a year.

Valbazen gets all worms that chickens can get. Higher dose and withholding feed required for tapeworms.

I have ivermectin (the frontline drug for dogs) but have been hearing that it has lost its edge, so ordered the levamisole. I had a fecal float done and the vet said it's roundworm, several searches indicated that levamisole would be good as a drench.

I'm not up to putting a pill down the throat of my chickens (it's me, not them). I don't have valbazen, if I did I would use it per your suggestion Dawg. My coop is clean, I've done the whole thing last weekend and sprayed it all real good with permethrin spray, then put sevin dust on the floor & nest boxes before the bedding.

I think I'm just almost panicking since this issue isn't going away with the treatments I've tried, I have to be out of town first part of August, and I have 9 chicks recently put in with the bigs--I don't want them to get this. If I drench, they all get a dose and then all get the retreatment. It should be here Friday, so Saturday they'll get a dose. Then, next Saturday, I'll be out of town, so they'll either get a dose early or a dose late (probably Friday morning before I leave) and then a 3rd dose the following Saturday. Any problems you see with my plan? Or dose? (2 grams powder in 1 gallon water, sole source o

Levamisole is a very good wormer. It'll take care of large roundworms, capillary and cecal worms. Sounds like you have a good plan, go for it. Have a safe trip.

I found this:

Levamisole residues in chicken tissues and eggs.

Abstract
Levamisole is currently being used to treat capillaria infection in chickens even though there is no published withdrawal information available for levamisole in chickens. Tissue residue withdrawal of levamisole in chickens was studied in 32 healthy broiler breeder chickens at the age of 32 wk (peak of egg production). Levamisole residues in chicken tissues, eggs, and plasma were determined by HPLC with ultraviolet (UV) detection at 225 nm. The highest level of residue and longest withdrawal after oral administration of 40 mg/kg levamisole to chickens was in the liver. On d 3 the level of levamisole were undetectable in the plasma. On d 9, levamisole residue in eggs was 0.096 microg/g and on d 18 it was 0.06 microg/g or less in all the analyzed chicken tissues. Those levels were lower than the recommended maximum residue limit (MRL). The withdrawal time for levamisole in chickens was longer than for other species tested, which is due in part to a larger dose of levamisole being recommended for chickens. In conclusion from this research, 9 d are needed for levamisole in eggs to be less than the MRL, and 18 d of withdrawal are needed before medicated birds are slaughtered if their tissues are to be safe for human consumption.

Information published in 2005. Since then, withdrawal times and acceptable drug residues in eggs and meat have gotten much tougher, which is why Levamisole, lovely product that it can be, is no longer approved for poultry. Actually there's currently nothing approve that will kill tapeworms, so helpful!

Was it ever approved for use in laying hens?

 

[Folly's place]

I have no idea, but it isn't now!
Ivermectin is NOT the same as Frontline, BTW, and I'd use Ivermectin way before using Frontline on my chickens!
I try to stick with approved drugs, realizing that approvals change over time.
