Beating Beetles and Moles the Natural Way

Ever notice that when Japanese beetles show up, moles often aren’t far behind? It’s not a coincidence. The beetles lay their eggs in your lawn, the grubs hatch and chew away at your grass roots, and before long the moles come tunneling through to eat those fat little snacks.

But here’s the good news: you don’t have to fight them alone. Two natural helpers—beneficial nematodes and milky spore—can make a world of difference.

Why They Work So Well

  • Nematodes are microscopic worms that patrol the soil and take out beetle grubs (and other pests) fast.

  • Milky spore is a bacteria that only targets Japanese beetle grubs. Once it’s in your soil, it spreads and protects your lawn for years.

  • Fewer grubs = fewer moles. It’s really that simple.

Benefits at a Glance

  • Safe for pets, people, pollinators, and earthworms.

  • No harsh chemicals.

  • Quick relief from nematodes, long-term protection from milky spore.

  • You get healthier soil and a healthier lawn.

How to Use Them

  • Nematodes:

    • Best in spring or late summer.

    • Apply in the evening or on cloudy days (sun can harm them).

    • Water before and after application so they can move into the soil.

  • Milky Spore:

    • Best in fall, when grubs are feeding actively.

    • Sprinkle in a grid pattern across your lawn.

    • Needs a few seasons to build up, but once it does, it keeps working for up to 10 years.

The Takeaway

Think of nematodes as your quick-response team, and milky spore as your long-term security system. Use them together, and you’ll not only knock back Japanese beetles, you’ll also make your lawn a lot less inviting to moles. Now’s the time - in fall - to apply milky spore.
