Oxalic acid treatment.

[reigate]

Advice please. I have one colony to treat using the trickle method. The amount of Apibioxal to use is 3.5 grams. How is the best way to measure this amount as it is a small amount.

A digital kitchen scale works well for my purposes. The quantities really do matter so don't guess/approximate.

I have more hives now so I use most of a packet but when I was in a situation similar to you I didn't measure it out but used the manufacturers instructions to make the whole lot up and what wasn't used I threw away. That way there is no measurement and no doubt as to the correct dose. I only use it once a year so would buy a new packet every year anyway and certainly wouldn't use a packet that had been open for 12 months.

Oxalic acid

Hi Gilberdike John, I can’t see why people aren’t just using oxalic acid and making it up with 1:1 sugar solution. This Api-Bioxal is only oxalic acid cut with fillers. Oxalic acid on its own is cheap as chips. (I’m a Yorkshireman)

Because it's illegal

The only reason is that its not legal. Now if you could buy pharmaceutical grade oxalic acid, like you can buy methylated spirits for example, that would be a different matter.

Why would that be different?
It would still be illegal to use it as a varroa treatment.

Now it wouldn't be a different matter because it wouldn't be licensed for use with bees. Also you would need a license to buy this chemical as it is on the poisons list (although no-one seems to ask for it or check)
