good question and not an answer easily obtainable with online searching. Many reviewers don't think it works at all. What is absent is anything saying it IS harmful to bees.

Yep. And interestingly I couldn’t find the constituents listed anywhere my wife thought she’d email the company but they’re bound to say it’s ok.

I have always a rule that says, "do not use a product that does not advise you of its active ingredient on the label or cannot supply an MSDS".

 

I have referenced these websites for this information;

 

The UK website does supply a MSDS - http://www.grazers.co.uk/wp-content/uploads/2017/08/commercial-Grazers_SDS.pdf

This identifies the active ingredient as calcium chloride.  The product strength is between 15% to 25%. (see EPA comment below)

The farmer based product details are here; http://www.grazers.co.uk/products/farmers-growers/

 

The NZ website is Hunkin Garden Products - which presumably imports product from the UK. 

https://www.hunkin.co.nz/slugrepellent.html

There are no labels or MSDS supplied for any of their products on this website.

One concern for NZers is that the website has a warning - NOTE: Unable to export to Australia due to quarantine restrictions.

So how did it get into NZ past our biosecurity folk at MPI?

 

Calcium choride is a hazardous substance according to the HSNO Act and is regulated by the EPA.

It is considered acuetly toxic to rabbits and rats, so that explains why it is being used. 

For the active ingredient the classification is as follows;

https://www.epa.govt.nz/database-search/chemical-classification-and-information-database-ccid/view/4728

For solutions stronger than 25% their classification is as follows;

https://www.epa.govt.nz/database-search/chemical-classification-and-information-database-ccid/view/4728

 

I have not yet found or obtained any data on toxicity testing for bees.

 

So all I can reccomend, if it the manufacturer cannot give yout he all clear as being safe for your bees - then DO NOT USE IT.
