A Taste of Life at Windrush Alpacas

Ticks or Mosquitoes – They Both Bring Trouble

 I had a call

 

 

 yesterday from an alpaca breeder who was concerned that one of her female alpacas was having a problem due to ticks.  The breeder had noticed her alpaca staggering as if she were drunk, she had also noticed her carrying one ear back and on checking the alpaca’s ears had found ticks in them, which she removed. 

 

 

Ticks can cause a condition commonly referred to as tick paralysis.  It is caused by the secretions of the female tick and can cause an alpaca to die if left untreated.  Unfortunately alpaca ears are an ideal environment for ticks to thrive in, and due to the anatomy of the alpaca ear, ticks can easily get into the area of the ear that cannot be seen by the human eye or even by using an otoscope.  I know of one alpaca breeder who having realized that one of her young alpacas was having a problem took her to a veterinary teaching hospital where under anesthesia they removed 16 ticks from the alpaca’s ears. 

 

In early 2006 we experienced a bad case of tick paralysis in one of our alpacas TeQueely. TeQueely’s story is one that illustrates not only how severe and life-threatening ticks can be, but also is testimony to TeQueely’s will to live.  Fortunately TeQueely’s story had a happy ending and this year she delighted us by producing her first cria, but there are other alpaca breeders who have not the same luck as we did.

 

I cannot stress enough how important it is to be vigilant for ticks in your alpacas ears, or on any other part of their body.  While not everyone has the skill or time to check every alpaca ear with an otoscope, the least they can do is treat the alpacas ears every month during active tick season and watch for signs of ticks at other times of the year.  I hate to recommend treating every month on a routine basis as over time the ticks could become resistant to the treatment you are using.  Certainly in TeQueely’s case Ivermectin, a commonly recommended treatment for parasites and ticks, was not effective at all on the ticks on our property.  We live in cattle country where I am sure Ivermectin has been used repeatedly over the years perhaps leading to a tick that is now resistant to Ivermectin.

 

We currently use Adams Fly Spray and Repellent for Horses for our ear tick treatment; another product used by some breeders is Catron IV.  With the Adams treatment we put 2 cc into each adult ear, 1.5 cc into each weanling ear and 0.5 cc (or even maybe less if the cria is tiny) into each cria’s ear.

 

The breeder who I spoke to yesterday took her alpaca into her vet who checked to make sure that all ticks that could be seen with an otoscope had been removed.  The breeder will now follow a plan of regular treatments and examinations of her alpaca’s ears to combat any new ticks that may hatch.  She has some work ahead of her, but it will be worth it if she restores her alpaca to full health.

 

While the breeder was at the vet, the vet also mentioned to her the possibility that the alpaca’s problem was West Nile Virus, a terrible virus that is carried by mosquitoes.  As a precaution the vet has taken blood samples from the alpaca for a Complete Blood Count and West Nile Virus testing.  The West Nile Virus test typically takes a few days which may be too late if the alpaca does have West Nile Virus, but the alpaca breeder is keeping a vigilant eye on her alpaca and if the alpaca seems to be deteriorating she will have the vet treat her for West Nile Virus. 

 

In New Mexico we have recently had heavy rains, over the weekend at our farm we had approximately 3.25 inches of rain in two days, which is unusual for us. The increase in water and moisture will lead to a surge in both the tick and mosquito populations and we will need to be alert to any signs of problems with the alpacas.  We have noticed that our dogs have recently been picking up ticks despite us treating them and the yard we keep them in, so we know the ticks are around.  I am sure it is only a matter of time before the mosquitoes start appearing too.

 

I will keep my fingers crossed that the breeders alpaca makes a full recovery, hopefully her actions of removing the ticks from her alpacas ears, consulting with her vet and treating the alpacas ears will prove to be fruitful.

  1. We have never had a problem with ticks on our alpacas. Mostly because we have a bunch of chickens running around the pins. Its something to consider. My sons used to get ticks all the time when we first moved out here to the farm, but after getting those chickens, we have seen no ticks, slugs, snails or anything else buggylike near the pins. Might be something to consider, plus you have the added bonus of fresh eggs everyday! :) Just got 11 new chicks last week to join the other 6 in another month out there. Good luck to you though.

  2. Hi Ginger,

    Thanks for your comment. We have considered chickens or guinea fowl in the past but as we have a den of coyotes living across the road from us we are concerned that the birds will attract the coyotes onto our property. At the moment he coyotes visit the neigbouring fields rather than our property. Have to agree that you can’t beat those farm fresh eggs. We used to have chickens before we moved to our current place and those eggs were just wonderful.

    Good luck with your new chicks!
