That will provide some relief for manged foxes?

I saw one come out the other day that wasn't as severe as the one I dispatched, but have no doubt it is just a matter of time before it is.

Napalm?

Anything a little less expensive?

Foo Gas.

Drop baits in the area with Ivermectin in them.

Gasoline, powdered laundry soap and a shot of fuel oil isn't that expensive.

Can't believe you just shared that.

That works on lice but I don't know about mange. It might

100% will work on mange mites, however 2 problems:
1). How do you keep the 1st fox along from eating all the baits ? And is there a lethal dose of ivermectin ?
2). There has been some evidence that mange mites can persist in the den in the mild winters we have here.

Hobbie: My father and Grandfather had a fool proof way of dealing with dens near the marsh. Call me for details....

might try Permethrin , it kills the mites that cause mange

powder might work the best dust the den

or mix the liquid like you were treating a dog kennel and be generous with your application at least the cost is low to try a quart which makes about 16 gallons is about 15 dollars at most farm stores.

you could try using oil it might have greater sticking /transfer power from den to fur.

Mange mites only live on the host animal. Not in dirt or grass. They cant survive in either. Ivermec is a pretty safe drug. Takes a tremendous amount to cause trouble. Best thing to do is catch them and give a shot if thats doable. I trapped hard around my house two years in a row when coyote mange got bad. Pelted the good ones and gave a shot to the mangy ones and released them. I cant say for sure I efected the mange problem but it was significantly lower the third year. Still dont see a lot of it.

You say you gave the mangy ones a shot then releasing. Werent you worried about them infecting others before they were cured?

No. I had no place to quarentine them either. Those mites are dead pretty quick once you inject them. Probably safe to other animals in a few hours. Certainly no more than a few days.

BTW it stays in their system about a month

This. I would do the bait thing, 2 oz piece of meat injected with 2 cc of Ivermectin and scatter a few every couple of days for a week should insure they get enough, I think. That is over doing the dosage in hope it gets ingested and recognizing that some will be wasted.
If I trap and inject .5-1cc under the skin at the neck I'd be sure. Or give 1 cc orally.
This will also worm them and keep lice and ticks off for about three months. Disclaimer I am not a vet and the above is only a thing that I would try based on my use of the drug with huting dogs and a discussion with a veterinarian. Caution If the canine has heart worm the dead heart worms resulting from the treatment may stop the heart causing death. Caution if the canine is collie or part collie they may die.

Goldnut, they would just about need to rub each other or lay down together for the mites to transfer. Likely that the mites will be dead before that happens and also likely that without the treatment they would spread the mites. I have read that the mites can live less than about 24 off the animal, maybe less than 12 hours, with out the animals body heat. So there is little likelihood of the mites spreading from a bed or from a dead animal.

Dog dose of Cattle Ivomec is .1 cc per 10 lbs. 20 cc is good for 200 lbs. You must have big fox.

Interesting info here. I just thought that they would be spreading this in the den where they would be close to each other.

Gentlemen, the mites die without heat but the mite eggs can survive longer.

Most likely any treatment of the den would spook them off?

Lot of misinformation out there. they ONLY lay eggs under the skin of a host. They are host specific. Fox mites don't infect dogs or coyotes and vice versa. No eggs are lain in dirt or grass or anyplace except under the skin of a host animal.

X2 what Danny says. That is what I know about mange also.

I wish I knew more about the life cycle of the lice that have been infesting yotes. It is a wide spread problem, that seems to be getting worse. There is very limited info out there about lice, and I really don't enjoy throwing away half of my catch.

this should work well or ivermectin horse paste

Have to wonder after the actions of our dogs when getting oral doses of it if a fox will eat a bait that has been injected. They won't eat a cow after being injected with antibiotics.

Contaminated dens last for years

The best way to prevent natures diseases from thinning out overpopulated animals is to manage the numbers through trapping.
Seen mange on my line once in 34 years in fox,when I first got the line.
Wolves have shown up with the chewing lice from time to time.When more trappers were taking wolves in the past the lice was rare in wolves.Now because of so many vacant traplines in the North,it can be a problem since wolves range so far,it takes more than one trapper to manage them on the landscape.

Get a few here with it. They get taken care of.
Eliminate the ones that are spreading it.
IMO it would take a series of treatments to get rid of it, even then extreme cases are hard to rid.

no mites in dens for days let alone years. one shot of ivomec is a cure.

there is a type of mange dogs get when they are allergic to their own skin mites. we all have skin mites living on us eating dead skin. that allergy in dogs requires a constant treatment of allergic symptoms. that however is not the sarcoptic mange that ruins fur and eventually causes the death of the host animal.

Mange doesn't always kill the animal.The fur council had a nice wolf pelt in their fur kit,and a scrapbook full of pictures of the same wolf when it was collared a couple years earlier by the MNR.At the time it was collared it was bad with mange.

My buddy had a dog like that he treated and treated without any success. Must have been that allergy ..
I see hairless coyotes in the Dead of winter some def find a way to survive . See them up around hay piles alot.

if your dog develops the allergic reaction mange a vet can give a shot every month or so that will provide relief. wife has a little lap dog that will drive you nuts scratching and biting herself without those allergy shots

I've seen yotes die down to a very small population twice in my life. Both times, it killed the pups in the dens and shortly after they started moving. But I have caught a lot of old coyotes that have the scars from having the mange, and in some cases were in the process of growing their fur back. They are survivers! Now fox.....not so much. Fox get scarcoptic mange, they are DOA.

Now the lice, I have seen yotes clean up from year to year. About four years ago, all I was catching was yotes with lice. I quit on them by thanksgiving, they were so infested. The next year, I didn't catch a single one with lice. Last season, I threw half of the catch away in Ks, and a third in SD. I wish some studys would be done to find out a lot more of how it is propagated, where it comes from in the environment. If you google chewing lice, it just tells what they are but doesn't address they're interaction with canines. It is a wide spread problem that little is actually known about. It has been around for years though, as I saw it back thirty to fourty years ago, but at that time, I thought it was mange that hadn't gotten bad yet! We always called a coyote with a fur problem....mangy!

you would think someone would create a fashion trend out of thin pink haired in the crotch coyotes

The lice is also a problem over here Lee , they get real thin in neck and shoulders? ^ and pink inside the legs
