Japanese beetles are one of the most destructive garden pests. As adults, they ravage your flowers and vegetables. As young grubs they devour your lawn's root system, and they attract skunks and moles. Grub Guard beneficial nematodes are naturally occurring microorganisms that live in the soil, feeding on Japanese beetle grubs. Unlike chemical controls, they won't harm earthworms or most beneficial insects, and they are safe around pets. Single-application sponge. The 1 million size will treat 2,000 square feet; the 6 million size will treat 12,000 square feet.

  • Contains two species of beneficial nematodes: Steinernema carpocapsae and Heterorhabditis bacteriophora
  • Sponge is 2-1/2" x 6"
  • 1 million size will treat 2,000 square feet
  • 6 million will treat 12,000 square feet
  • Also controls Colorado potato beetle grubs, cutworms, root weevils, flea larvae and other soil-dwelling insects

      I used a watering can and kept adding the concentrate toeach can of water. Took time but I was new to this type application (in a sponge, really), next time will use a sprayer. I have high hopes but will take time to really see the results.

      Comments about Grub Guard:

      I had a cute little skunk digging holes in my yard. Assumed that she was eating grubs. While I hated to take away her dinner, my husband was not pleased with the holes in the yard. I didn't want chemicals in the yard, so this seemed like the best solution. I sprayed the grub guard and I no longer have little holes. So I think this worked. (Since I did not dig up the yard to look for grubs pre- and post- treatment, I can not say for sure.) My only complaint was that it came when it came. I understand that there is an optimal time, weather-wise, to spread these guys, but I would have liked some say in when they came. You really have to spray them right away, as they are alive. They an stay in fridge for a while, but not too long.

              i got a inexpensive hose spray attachment, filled it with the right amount of water, threw in the sponge, gave it a good shake to dislodge the little ones, then sprayed the yard where there they have the best chance to survive, so they can grow up and take care of the grubs and insect eggs before they can become pests or attract larger pests

              A little time consuming with having to wet your lawn and garden before and after use, but the results are well worth it. I dig in the yard a lot. We sprayed it on 2 weeks ago and I haven't seen one grub. We've used it before, it's safe for the environment and absolutely love it.

                Not for the easily squeamish (some people have issues with spraying creepy crawlies on their lawn), but the product was simple to apply and pretty effective. My flowers are healthier, the lawn looks better and our flea problem has disappeared. The only con was the 2 hour window to spray after the concentrate was made.

                  Comments about Grub Guard:

                  I love these little nemotodes! Nemotodes are bacteria that use the grubs as hosts to lay there eggs. The eggs hatch and the larvae chew on the grub. Yum! The nemotodes have done an awesome job getting all the grubs in my yard. I have several kinds of grubs that hatch each spring and fall. These little nemos get them all! My yard and gardens have never been healthier. And this is so safe for all of us including our pets to be in the grass just after application.

                  The first time I used this was about 4 years ago. I had phoned Gardener's with a question on application (how do you know when your sprayer runs out of nemotodes and needs a refill?) Yes, put in some food coloring. It won't hurt the little guys.

                  Because of my freezing winters, I apply Grub Guard every spring. Warmer climates don't need to reapply. Check the product information for temperatures.

                  Read your directions on the package and you will be so satisfied with this product.
