A question for those who used Deosect.....

[Crazydancer]

The instructions say that once diluted, the solution should be used within 24 hours.
Does anyone know why? Is it just that the effectiveness would reduce?
Thanks!

I’m guessing that’s the reason. I’ve never tried it though and sponge it on, no more than once a week.

I tried mixing it up in a spray and reapplying. It definitely didn't work as well with subsequent applications

Do a patch test first.

I think it loses effectiveness. I put any spare in an old spray bottle and use as fly spray.

 

[Crazydancer]

Thanks all - that's what I thought. I had mixed it with another fly spray in a bottle, didn't know if I should chuck it, or could use it again. The spray I mixed in in with is a citronella based one.

I mix mine up and keep it for longer than 24hrs - still seems to work fine and when I checked with the vet he didn't have any concerns about me doing it this way

I mix it then sponge it all on. instructions say once every 4 weeks or every 2 weeks if flies or bad.
cant see why anyone should mix more than they need then keep it.

Does it survive after work wash-downs and so forth?

I mix up 500ml at a time and mainly use it in a spray bottle. Occasionally I do sponge it directly onto their head and necks.

It still works OK.

It clearly says on bottle use all diluted solution within 24 hours of making up.

I think whilst it is meant to work upto 3 weeks on the horse, it doesnt work as well if sitting in the bottle and then applied after a few days.

Personally I make it up, and spray horse until all I have made up has been applied. I want it on the horse and working. I only use every 2-3 weeks in bad fly season.

I hate applying it - affects my asthma and nasty to breath. Once occasionally is enough. I use other things inbetween.

I think it does survive washing, as I think it goes into hair and skin. Nasty organophosphate stuff! But needed sometimes.

 

[Floxie]

Thank you! I did think that would be the case but wasn't certain. I think I'll try it next summer.

Deosect is a pyrethroid not an organophosphate.
