Harvest Mites

Harvest Mites

The most recent information suggests that there might well be a link between Harvest Mites and SCI (Seasonal Canine Illness).  With that in mind, I thought we’d take a look at what they are and what to do about them.

Harvest Mites (known as chiggers or berry bugs) appear, as the name suggests, around harvest time – ie late summer/early autumn.  Harvest Mites usually infest field mice but can also live on the surface of the dog’s skin, and feed on skin cell debris rather than burrowing under the surface.

The mites themselves are just visible to the naken eye and often appear as tiny red or orange dots and form clusters – hence their name “berry bugs”.

Severe itching which is usually found on the underside of the abdomen or on the feet/toes
Irritation causing the dog to lick his feet
Larval stage mites may be visible between the toes
Larval stage mites may be seen between the skin folds at the edge of the ear flaps

Various insecticidal preparations and shampoos can be used in the treatment of Harvest Mites, although some dogs may require treatment with anti-inflammatory medication as well.  It is usual for this type of mite to just “disappear” following the first frost in September.

A great non-chemical treatment that has been suggested is something called Neem Oil.  Neem oil on the coat can be an effective deterrent to various critters including ticks, fleas and mites as it has a very pungent, savoury odour.  It is, however, worth noting that if you intend to use your dog for breeding any time soon, this treatment should be avoided as the smell can be very off-putting for any would-be suiter!  Apparently in some parts of the world it is even used as a contraceptive!

Another great way of treating Harvest Mites, particularly if you favour non-chemical alternatives is Diatomaceous Earth (DE).  Ive added a blog all about DE and its many varied uses on another post but one of our followers, Sue Craigie of Imbaliridgebacks.co.uk sent me this message about using it for Harvest Mites.  Sue writes “One of my Ridgebacks had a Harvest Mite infestation and I cleared it up completely by rubbing DE (Diatomaceous Earth) into the affected areas. Within about a week the mites and sores had gone and her skin was back to normal.”

    One of my Ridgebacks had a Harvest Mite infestation and I cleared it up completely by rubbing DE (Diatomaceous Earth) into the affected areas. Within about a week the mites and sores had gone and her skin was back to normal. This is a non-chemical way to clear the problem.

        no no, simply apply in its dry powder form and work into the fur 🙂

      Hi Sue. Do you rub the powder into affected areas or mix with water to make a paste? It’s not for our RR, it’s for our cat. We live very rurally and has been a big problem for him this year. Kris

        Hi Kris, you just rub in the powder dry directly onto the fur/skin

    Last year was a terrible year for harvest mites (and they are off again!). I telephoned Lintbells (show people will know them as the Yumega people) to find something for one dog who was suffering – as was I!! They told me that their Skin Cream with Silver and Calendula was very effective. I used it all last year for both the dog and myself and it is brilliant. this year the dog (at the moment) shows no signs, but I have been really bitten and I react badly. It can be ordered on-line. I ordered some at 3 p.m. last Friday and the postman delivered it on Saturday morning – that’s service!

    Can harvest mites be spread from one dog to another by contact?

      Hi Carolyn, they are picked up from the environment, attach the host and drop off at a later stage in development.
