Problem with flyes

I just moved my yard, and close to new place there are pigs, thats why i have many flyes here, well maybe not only normal flyes, i dont know how they are called in english, but they bite a little.
So they attack my dogs ears all day long bitting and blood start to come, im nervous about infections and also ofcourse its irritating for the dogs.
I would like to ask if anyone dealed with this before?
Some spray for the dogs or the chainspace?
Any help would be appreciated
Thanks

 

When I was young we lived in savannah and had the huge flies.We always just called them horse flies.I was pretty young so
i dont really remember how they took care of it ,except they would put vaseline on the dogs ears.I dont know though,it might be really hard to get rid of them due to the pigs.

 

for horses but I am sure it would work for dogs

During the summer months flies are a major irritation to horses. There are a variety of fly repellents sold in equestrian stores but there are also remedies that can be made at home.
Common recipes often involve a combination of essential oils, available from many chemists and health food outlets. Such oils include eucalyptus, tea tree, lavender and sandalwood, the first three being the most useful. These are most commonly mixed with water in a spray bottle and sprayed on as required.

Other fly repellent recipes involve garlic, probably the most powerful natural fly repellent there is although the products of garlic-based fly repellents tend to be rather on the unpleasant smelling side, especially when combined with the likes of lavender oil.

'Internal' fly repellent have the effect of either causing the horse's body to secrete oils that will repel flies (garlic), or raise the pH (acidity level) of the horse's blood enough to put flies off from biting. Such repellents take time to produce an effect so combining these with a fly 'spray' as well will probably be the most effective.

Below are some of the more popular home-made fly repellents.

1. White wine vinegar, water and any combination of eucalyptus, lavender, sandalwood or tea tree oils Mix a few drops of each essential oil into a little washing-up liquid and add to the vinegar and water. Put the resultant mixture into a spray bottle and shake well before using. Variations include the addition of strong, cold tea instead of water, crushed garlic (although this can clogs the 'spray' mechanism of the bottle), meths, and Dettol.
   
2. Take a large lemon with a thick rind and slice thinly. Place in a bowl with a few sprigs of rosemary and cover both in boiling water. Allow to steep overnight and strain the mixture the following morning. Pour the mixture into a spray bottle and shake before applying. A similar response seems to be had by doing the same with leaves, stems and flowers from Elder bushes. (Slipping flowering elder twigs through your horse's browband can also act as a fly repellent.)
   
3. Mix one part crushed garlic to five parts water. Shake the mixture and leave overnight. Strain and pour liquid into a spray bottle.
   
4. An internal fly repellent. The addition of garlic to a horse's feed causes the skin to secrete garlic-scented oils that deter flies. Garlic powder can be bought from most saddleries and feed merchants.
   
5. Adding a little vinegar or cider vinegar to a horses water raises the pH of the horse's blood sufficiently to put flies off from
   

 

Thank you for your replys..

 

Check out a product by Farnam. Main ingredient is Pyrethrin. But you can buy it in a wipe form, or spray bottle form. It works wonders. Check it out online, I buy the wipe form. And I use a sponge for it, keep it in a ziplock bag, and just poor it on and wipe. And I also spray Pyrethrin around the kennel and yard area that they are in. It's a dark green bottle and you can't miss it. A lot of feed stores have it as well.
