Our winter has been very mild and dry and our spring looks as if it is going to be warm, dry and windy (as always!). Already our temperatures have hit the 80 degree mark a couple of times, the fruit trees are starting to blossom and everything living is getting signals that spring is here. It is still possible for us to have a downward swing in temperature; a late frost is not unheard of here and unfortunately will kill the fruit tree blossoms reducing our chances of any peaches or apricots from our trees.
Along with the warm weather the insect population is starting to become more visible. We saw a yellow jacket (large wasp type insect) the other day, crickets are starting to appear and the dreaded ticks have also started to make an appearance.
Unfortunately our sandy soil and warm temperatures make an ideal environment for ticks, and even worse alpaca ears are an ideal place for ticks to take up residence. The warm, sheltered environment of the alpaca ear is just the type of place a tick likes to live in and ticks will happily feed not only on the alpacas blood but also on any debris generated by the alpacas ears.
We had a bad run in with ticks in the past, our girl TeQueely had a terrible fight with tick paralysis (See entry December6, 2007) and my battle to save her has made me an avid campaigner for tick prevention.
Many alpaca breeders do not realize that their alpacas may have ticks in their ears. Often there are very few signs of the ticks, sometimes you will see the alpacas shaking their heads, sometimes an alpaca will hold an ear back, occasionally there may be some black debris found in the alpacas ear, but often the signs are few to none.
Having spent time exploring an alpaca ears with an otoscope (don’t try this unless you have had some education from your veterinarian as you can easily damage the alpacas ear drum) I am amazed at how many hiding places in an alpaca ear there are. With an otoscope and alligator forceps I can usually locate any offending ticks and remove them, but ticks are also capable of hiding deep in the ear canal past where the otoscope can reach.
So what is to be done about these tiny but potent creatures? Well as often is the case an ounce of prevention is worth a pound of cure and there are few things you can do to keep the tick population down.
Some alpaca breeders keep guinea fowl or chickens with their alpacas, as the birds will eat any bugs they find. This can be a good option; the birds will pick up bugs not only from poop piles but also from roll spots and other areas around the pasture. If you are keeping birds with your alpacas make sure you get them from a farm that is very conscious of the health of their birds, the last thing you want to do is bring viruses or nasty bacteria onto your farm. Also try and feed unmedicated feed, as the medicines in chicken feeds are fatal to alpacas. If unmedicated feed is not available then make sure it is kept securely away from the alpacas.
Putting diatomaceous earth on roll spots and poop piles may also help keep down the tick population. Make sure that you use food grade diatomaceous earth as it is safe to be used around livestock, the commercial and pool grades of diatomaceous earth are not suitable for use around livestock.
I have heard of some breeders feeding garlic to their alpacas to help reduce ticks and other parasites. I have not tried that yet and am still researching the pros and cons of using garlic on alpacas.
Finally treating the alpaca’s ears during tick season will kill the ticks and depending on what you use may also kill the tick eggs. We prefer to use Adams Fly Spray and Repellent for horses, it kills both the ticks and the tick eggs and we have found it to be very effective. We shake the bottle well (the solution tends to separate when it is sitting for a while), pour some into a container and then draw up 2 cc in a syringe. We administer 2 cc per ear on the adult alpacas, 1.5 cc per ear for the weanlings and 0.5 cc per ear on the crias. We put the syringe in the ear, depress the plunge and then massage the ear before letting go. Make sure you stand well back once you let go as the alpacas will shake their heads and some of the solution will fly out of their ears and you don’t want to get it in your eyes.
Over the last year or so the Adams Fly Spray and Repellent for Horses has become a little difficult to find. If Adams is not available I have heard of Catron IV being used, but as it comes out in a foam I find it harder to ensure the correct dosage
Once tick season arrives we treat our alpacas ears about every thirty days. I don’t usually go for routine worming or parasite prevention as I feel that overuse of certain products has resulted in some parasites becoming resistant to the products, but there are some circumstances when you have little choice but to treat on a regular basis.
Having had one experience of tick paralysis in the herd I don’t want to have another, so for now we will continue treating the alpacas on a regular basis and in time we may find other solutions that are just as effective in preventing ticks – and who knows we may even invest in some chickens for our own herd. Tick prevention and farm fresh eggs – sounds like a good option to me!
