Not all grub control products are created equal. If you've browsed the lawn care aisle looking for grub solutions, you've probably noticed dozens of products claiming to kill grubs. Before you grab just any bag that says "grub killer," you need to understand the difference between preventatives and contact killers—because choosing the wrong one could leave your lawn unprotected.
Preventatives vs. Contact Killers
There are two main categories of grub control products. Contact killers are designed for active infestations, typically applied in the fall when grubs are already feeding on your lawn. Preventatives, on the other hand, are what you need to apply before grubs become a problem.
For homeowners in Midlothian and Prosper, timing is everything. Applying a preventative in late spring or early summer gives your lawn protection before grub eggs hatch.
The Active Ingredient That Matters
When shopping for a grub preventative, look for products containing Imidacloprid as the active ingredient. This ingredient offers a long residual, meaning it stays active in your soil for an extended period. This extended protection is crucial because grub hatching times can vary from year to year.
Once grubs hatch, Imidacloprid kills the small larvae before they grow into their destructive feeding stage. By the time you notice lawn damage from grubs, it's often too late—which is why prevention is so important for North Texas lawns.
Popular Imidacloprid Brands
Several brands carry products with Imidacloprid:
- Zenith
- Merit
- Bandit
Don't get too caught up in brand names. The key is checking the label to confirm you're getting the right active ingredient. Whether you're in Prosper, Waxahachie, or anywhere in the DFW area, the ingredient matters more than the packaging.
When to Apply
Apply your grub preventative before you have a problem—typically in late spring through early summer in our region. Waiting until you see damage means the grubs have already done their work, and you'll need a contact killer instead.
