45 Seems to work on Crab Flies
Verified Purchase

By on 22 October 2020

We had cases of Crab Flies sending horses crazy locally, so I bought some as a precaution. Before I needed to use it a neighbouring horse had a crab fly and was reacting very badly, I loaned my spray to the owner, who tells me the horse calmed after a while and had no problem thereafter. I would assume that it worked well, and shall save the remainder for emergencies.

55 Replacement wonderful
Verified Purchase

Works so much better and effectively than I was expecting. Turned out well worth waiting for replacement after initial delivery was damaged in transit.

We've tried most of the others available and have found none are as effective, quick acting or long lasting as Tri-tec

Instructions say do not sparay directly on horses?

Linda Wells

  • VioVet customer since 2013
  • From: Lincolnshire, United Kingdom

instructions say dont spray directly on horses but judging by reviews people have not read this ? Is it a fly spray for horses?

  • VioVet Staff

Hi Linda,

This product should not be applied directly to horses. It is a spray for stables and lorries to kill flies inside that would attack your horse.

Hope this helps,
