I use it on my birds regularly as some tend to get scaly leg. They free range a lot, so are bound to pick some things up from the wildlife. A few drops go a long way. Please note that there is an egg withdrawal period after use. That is fine - gives us a chance to catch up!

Gapeworm in canaries

Heidi

Hello would this treat gapeworm in canaries? They're gasping for air and I'm not sure what to do

  • VioVet Staff

It's typically effective against external parasites (mites, lice) and some internal parasites like air sac mites.

However — gapeworm (Syngamus trachea) is a type of nematode worm that lodges in the trachea of birds and causes respiratory distress (the characteristic gaping). While ivermectin can have some efficacy against certain nematodes, gapeworm is not typically listed as one of the primary parasites Harka-Mectin is labeled to treat.

Egg withdrawal with harka-mectin

Cecily Sargent

Do you need to stop eating eggs after dosing chickens with Harka-mectin
If so for how long
Many thanks

  • VioVet Staff

Harkers Harka-Mectin is NOT for use in chickens, so I cannot advise on this.

Oral use?

K Weave

Can this be given orally or only topically. My birds do much better with oral applications.

  • VioVet Staff

Harka-Mectin is a spot on treatment and should not be given orally. If you are looking for an oral medication for pidgeons that treats external mites then I suggest Harkers 4 in 1 Soluble which is administered via the drinking water.

Grape worm.

Helen Brown

Will this be effective for grape worm in chickens?

  • VioVet Staff

This medication is only licensed for use in pigeons, any use in chickens is off license and we can only dispense for this alongside a written prescription from your vet.
Flubenvet or Flubendazole 1% will treat gapeworm and these are licensed for use in chickens. I recommend ordering this instead, these are over the counter.

Lewys Will it clear air sac mi

Will it work for air sac mites in budgies

  • VioVet Staff

This product is only licensed for use in pigeons, if you are looking for a licensed mite treatment in Budgies then I would recommend using Beaphar Anti Parasite spot on Small (Canary/Budgie).

Use in chickens?

VioVet Visitor

Can this be used on chickens.for red mite?

  • VioVet Staff

Red mites spend most of their time not on the birds, but in nooks a crannies near to where birds roost. It is better to apply a suitable product to the perches etc, but the Harka-Mectin will be effective against mites which climb onto the birds to feed.
