Its that time of year when people are seeing Red foxes and coyotes with Sarcoptic mange. THIS IS TREATABLE AND YOU CAN DO IT!
Treating Sarcoptic Mange in Red foxes,
by Elise Able Fox Wood Wildlife Rescue, Inc
Symptoms:
Fox out during the day, but also laying in the sun, acting lethargic, eating under bird feeders, thin fur on tail, thin fur on body, crusty eyes, scratching a lot, shaking head as though there is a bug in their ear. Swollen, scaly feet, laying in baled hay, going into culverts. A limp in hind legs. Red foxes are not nocturnal, so there must be combined symptoms, not just being out during the day.
Baby foxes, especially those younger than 5 weeks of age hide signs of mange well, as the puppy coat doesnāt fall out, it is thick and you have to part it and look very closely. They will die quickly
What you can do right away:
Start conditioning by putting out some dry cat food or dog food and hot cooked chicken in a spot where the fox will find it easily.
If possible, turn home surveillance toward the feeding station or use a trail camera to see who eats the food, and if a fox, what time. Foxes tend to keep a schedule.
Treatment:
Quickest, easiest, most effective: 3-month Bravecto chew
A single dose of the three-month Bravecto (fluralaner) Chew for a 10 lb. dog wrapped in two Greenies hickory smoke flavor two capsule size pill pockets. Form into a round meatball that can easily be tossed to the fox from a window, car, or left at a feeding station once fox is conditioned. These meatballs are also easy to pick back up and try again later in case the fox doesnāt eat it.
Bravecto Chews are much more economical when a larger size is divided. Use a razor blade, cut at room temperature. Wrap up the remaining chew in original container, then Ziplock bag. It can be refrigerated. Take advantage of promotions and sales!
88-123 lb. will treat 12 foxes
44-88 lb. will treat 8 foxes
22-44 lb. will treat 4 foxes
9-22 lb. will treat 2 foxes.
Donāt refrigerate Pill Pockets, it will dry them out. Store in a Ziplock bag or covered container room temp.
By Prescription in the USA. Most veterinarians wonāt provide for a wild fox. If you get some for your dog, chances are you can have enough to cut off enough for a 10 lb fox and have enough left over to protect your dog from fleas, ticks, and mites for three months.

Alternative Treatment "
Using Ivermectin
Ivermectin: Less expensive, over the counter, easier to obtain, but requires multiple treatments for at least a month
Recommended: 50 mL bottle of 1% injectable Ivermectin for cattle and swine. Works orally.
You can pry off the rubber stopper top with a bottle opener, or use a 16 or 18 gauge needle and 1 mL or 3 mL syringe. Insulin needles will not work.
Purchase at farm stores or online. Different brands are Agrimectin, Durvet, Bimectin, Noromectin
CAUTION: Do NOT use the Pour On ā it is deadly if ingested.
Ivermectin Horse Paste is very difficult to dose accurately and may have palatability issues. A red fox weighs 10 lbs, each notch on a tube of horse Zimecterin paste represents 50lbs of animal weight, or as specified on box
Caution: Make sure there are no collies, collie breeds or collie mixes that might eat this. Collies, shelties, border collies, Australian shepherds or high mixes might be sensitive to Ivermectin and experience ataxia.
Ivermectin
Condition fox to daily food to make sure the fox will find the ivermectin. You will need to feed the fox daily until the treatment is done in order to maintain the conditioning and treatment. If the fox leaves before all eggs are hatched and the life cycle of the mite is complete, then the fox will get re-infected.
Treatment:
0.2 mL once every five days for 30 days. Its OK, if a fox gets more than one medicated meatball at a time
At the den- Litter of fox kits 0.1 mL once every five days. Scattered around, with a few more meatballs than kits , scattered widely. If one kit gets more than one, thatās ok, ivermectin is a fairly safe medication

Troubleshooting tips
How do I make sure the fox gets it? This is why we use conditioning with food ā dry cat food and hot cooked chicken. Put it out in the early morning to reduce raccoon, opossum, skunks, etc from getting it. Use a camera, foxes will keep a schedule. If the fox is in a culvert or under a shed or deck, you can pt the medication-laced meatball underneath or inside the culvert with it. Also, meds can often be tossed from a window directly to the fox. Meds can be tossed from a car window to the fox. Pick them back up and try again if the fox gets frightened and leaves the area, not eating the meds.
There is more than one fox. How do I target the sick one? Mange is very contagious, so they should all be treated if theyāre coming for the same food. Do the best you can, timing is the key. Foxes tend to keep a schedule.
Should I trap the fox and relocate it? Relocating without treating will infect a new population. The fox in question will also die. What if it has kits depending on it? Treat, and then if needed, use scare balloons to discourage fox from coming back.
Should I trap the fox and take it to a wildlife rehabilitator: What if it has babies? Also, stress from capture can cause a sudden downward spiral from shock and a quick death. The fox has the best chance of recovery in its own environment.
Can my dog catch Sarcoptic mange from the fox? Your dog can catch Sarcoptic mange from the grass, like the fox did. In order to catch it from the fox, it would have to have physical contact i.e. roll on a dead fox. Protection through the Spring and summer is a good idea. Bravecto, Nexguard , Simperica, Trifexis, Seresto collar all protect dogs from Sarcoptic Mange mites. However, these meds donāt all necessarily cure mange in the fox, and multiple doses are generally necessary, i.e NexGuard needs three doses, one every two weeks for 6 weeks.
Will the Bravecto kill my cats if they eat it? Bravecto for dogs and cats have identical ingredients and are the same strength. The fox is the same average size as a cat (10 lbs)
What else can I use to put the medications in? Anything that the fox can eat in a single bite. Foxes love sweets too. A marshmallow or glazed donut hole work nicely. Some people say to use hard boiled eggs, but these are too large and must be broken up to be eaten. The meds may fall out and go uneaten.
How can I tell if my fox is getting better? Fur may not grow back until fall, so look for spring in the step, clear eyes, being more skittish, and not being seen as much, less scratching and ear shaking
