Ronnie, I'm glad you can confirm its existence. I tried it from Summerhill too. They were the usual color. I've tried GEO, Plant World, Chiltern's and a score of others to no avail.
So, I am no longer giving up. 😂. You give me hope.
The assertion about pest control properties must be a relatively new one. Sources that make claims like that are likely unreliable in every way. Makes me think of something you would find on EBay or from an individual on Amazon.
