Excellent product and customer service at a good price
This product has saved my lawn which was being dig up by badgers. Not only are the nematodes effective but the follow-up and customer service of this company are second to none. I highly recommend them.

Good product
had quite a lot of this alongwith Xen Tari. It works as we've not had repeated problems with leather jackets.

Didn’t work.
Unfortunately these didn’t work. The birds did a better job of eating the leather jackets. Also very expensive.

Easy to use, but it may take a few applications
Having a very infested lawn on a new build house I have used this product over the last 2 years and again at the start of this year (2026). You may need to use double doses at the beginning of the year (May) application is by watering can. Can only wait and see in September /October. It's an easy product to use if you follow the instructions carefully. It's safe to use and does harm pets.

Worked a little
We got these as we had weather jackets in our garden and so we did what it said and double dosed. It killed a few but I did find others still alive. Will try again in October ready for next year.
