What is the best source of pesticide containing nematodes?

I think you have your terminology mixed, nematodes are living organisms, not to be confused with pesticides

However we know what you mean, never used them myself but I think you have to buy online because they are living and do not have a "shelf life" suitable to sitting in B & Q for instance

No doubt someone on here has used & can advise

The sort of nematodes that you are probably thinking of tend to be target-species specific, so if you let us know what you are trying to control we might be better able to advise.

And it's rather cold for nematodes. They need to be applied when the soil is warmer.
