Pest Control

Spot and stop lawn-damaging insects early with identification guides and proven treatment timing for grubs, chinch bugs, armyworms, and more.

11 articlesfall season

Lawn-damaging insects work fast and often stay hidden until the turf above them is already dying. Grubs chew through roots from below, chinch bugs suck moisture from grass blades in hot, sunny spots, and armyworms can strip a lawn bare in a matter of days. Knowing which pest you are dealing with, and when it is active, is the difference between a quick rescue and a season of damage.

Correct identification comes first. Grub damage shows up as turf that lifts like loose carpet, chinch bug damage looks like drought stress that will not green up after watering, and armyworm damage spreads in a visible front across the yard. Each pest has its own detection test -- a soil sample for grubs, a flotation test for chinch bugs, a soap flush for armyworms -- and our guides walk through each one step by step.

Timing treatment to the pest life cycle matters as much as choosing the right product. Grub killer applied too late misses the window before larvae burrow deep to overwinter, and preventive treatments need to go down before an infestation takes hold. Our guides cover identification, treatment timing, and prevention for the insects most likely to damage a home lawn.

Frequently Asked Questions

Common questions about pest control, answered by our expert guides.

How long until it's safe for pets and kids to go back on the lawn?

Treated grass is generally safe once it's completely dry, or after the product's stated re-entry interval if that's longer. Always follow the specific product label, since intervals vary by formulation.

Does this also kill grubs?

Only if the label lists grubs. Some granular flea, tick, and ant products do list white grubs, but grub killers are formulated for residual soil activity against beetle larvae — a separate use case with different actives.

Granules or spray for a yard with standing fleas right now?

Use a spray for immediate knockdown of adult fleas, then follow with a granular application for whole-lawn residual coverage. Sprays also let you target the shaded, moist spots where fleas breed.

Is there a pet-safe option that still works?

Yes. Cedar oil yard sprays are minimum-risk, plant-based products marketed as pet- and kid-safe when dry, and their labels list fleas, ticks, ants, mosquitoes, and chinch bugs. They're the lower-risk pick for yards with frequent pet and child contact.
