Common Lawn Pests & Signs of Infestation
Before choosing an insecticide, identify what's attacking your lawn. Different pests require different active ingredients — using the wrong product wastes money and time.
- Brown patches that peel back like carpet
- Increased birds or raccoons digging
- Spongy feeling underfoot
- Dead grass that won't respond to water
- Irregular yellow/brown patches

- Tiny bugs (¼ inch) with white markings
- Visible mounds up to 18 inches
- Aggressive biting when disturbed
- Multiple colonies appearing quickly
- Sandy soil pushed to the surface
- Chewed grass blades
- Small brown moths flying at dusk
- Rapid spread — can destroy lawn in days

- Buzzing around shaded/moist areas
Dylox 6.2 is the fastest curative grub treatment available to homeowners. Its active ingredient, trichlorfon, is a fast-acting organophosphate that disrupts the nervous system of grubs on contact — unlike preventative treatments that take weeks to build up, Dylox delivers visible results within 24–48 hours.
The key to its speed is immediate watering-in. The granules dissolve quickly and penetrate the soil where grubs feed on grass roots. Most grubs die within the first day, with near-complete control in 3–5 days. It's the product to reach for when you can peel back your turf in sheets and need results fast.
What it kills: White grubs (Japanese beetle, European chafer, May/June beetles), mole crickets, cutworms, sod webworms, annual bluegrass weevils.
Pros
- Fastest grub control available — works in 24 hours
- Curative — kills existing infestations, not just preventative
- Works even when grubs are large (late season)
- Easy granular application with a spreader
- Breaks down quickly — 48-hr active period reduces environmental impact
Cons
- Short residual — only active for about 48 hours
- Not preventative — use only for existing problems
- Requires immediate watering-in — won't work without it
- Higher cost than preventative options
- Limited pest range — primarily for grubs
Apply 2.3 lbs per 1,000 sq ft using a broadcast spreader. Water in immediately with 0.5 inches of water — this step is critical. Without watering, the granules won't penetrate to where grubs feed.
Taurus SC contains fipronil — the same active ingredient as Termidor SC — at a fraction of the cost. It's a non-repellent insecticide, meaning ants and termites can't detect it. They walk through the treated zone unknowingly, pick it up on their bodies, and carry it back to the colony where it spreads through contact and grooming. This transfer effect eventually eliminates the entire colony, including the queen.
What it kills: Fire ants, carpenter ants, Argentine ants, subterranean termites, roaches, crickets, spiders, ticks.
Pros
- Colony elimination — kills entire ant/termite colonies
- Non-repellent — insects unknowingly spread it
- Long residual — 90+ days of protection
- Same formula as Termidor but significantly cheaper
- Professional grade — used by pest control companies
Cons
- Slow acting — takes 30–90 days for full colony kill
- Requires mixing and a pump sprayer
- You may see increased ant activity initially
- Patience required — not for emergency knockdown
Permethrin is a synthetic pyrethroid that attacks the nervous system of insects, causing paralysis and death. It's highly effective against ticks because it provides both immediate knockdown and long-lasting residual protection — up to 30 days outdoors and 90 days indoors. The broad-spectrum formula makes it ideal for perimeter treatments.
What it kills: Ticks (deer, dog, lone star), fleas, mosquitoes, ants, roaches, spiders, chinch bugs, mole crickets, and 50+ insect species.
Pros
- Excellent tick control against all species
- Broad spectrum — kills 50+ pests
- Long residual — 30 days outdoors, 90 days indoors
- Indoor/outdoor versatility
- Affordable per treatment
Cons
- Strong chemical odor during application
- Requires mixing — not ready-to-use
- Toxic to fish and bees — avoid water and flowering plants
- Monthly reapplication needed outdoors
Demand CS uses microencapsulation technology — the active ingredient is enclosed in tiny capsules that stick to insects and surfaces. When mosquitoes and other insects contact treated surfaces, the capsules rupture and release the insecticide. This technology is especially effective for mosquitoes because the capsules adhere to foliage where they rest during the day.
What it kills: Mosquitoes, flies, gnats, wasps, spiders, ants, roaches, fleas, ticks, and 30+ insect species.
Pros
- Microencapsulated formula — superior residual adhesion
- Doesn't stain surfaces
- Low odor — minimal chemical smell
- Pet safe once dry
- Long-lasting — 90 days indoors, 30 days outdoors
Cons
- Requires pump sprayer — hose-end attachment won't work well
- Higher cost than alternatives
- Small bottle size covers limited area
- Requires mixing
Talstar XTRA combines two pyrethroids for dual-action control: bifenthrin provides long-lasting residual while zeta-cypermethrin delivers fast knockdown. This combination is especially effective against chinch bugs, which hide deep in the turf canopy — the granular format penetrates exactly where they live. Apply 2.3–4.6 lbs per 1,000 sq ft and water in immediately.
What it kills: Chinch bugs, mole crickets, fire ants, fleas, ticks, armyworms, billbugs, sod webworms, European crane flies, and 30+ lawn pests.
Pros
- Dual active ingredients — fast kill + long residual
- Odor-free granules — no chemical smell
- Broad spectrum — 30+ lawn pests
- Professional grade — used by landscapers
- Reapply every 90 days for season-long control
Cons
- Must water in — won't activate without irrigation
- Not ideal for grubs — better for surface pests
- Requires full even coverage — gaps leave pest refuges
Bifen IT is the best value in lawn insect control — full stop. One quart treats up to 44,000 square feet, which is nearly an acre. The cost per treatment is incredibly low, yet it performs at a professional level. Mix just 1 oz per gallon of water and spray your lawn, perimeter, or affected areas. It creates a contact + residual barrier that kills insects on contact and continues working for 90 days indoors and 30 days outdoors.
What it kills: 75+ insect species including ants, roaches, spiders, crickets, millipedes, earwigs, stink bugs, box elder bugs, fleas, ticks, mosquitoes, wasps, and many more.
If treating more than 10,000 sq ft regularly, the gallon size is about 40% cheaper per ounce and will last most homeowners 2–3 years.
Pros
- Incredible value — treats 44,000 sq ft per quart
- Kills 75+ pest species
- Long residual — 90 days indoors, 30 days outdoors
- Professional strength at DIY price
- Virtually odorless and doesn't stain
- Pet/child safe once dry
Cons
- Requires mixing and a sprayer
- Moderate kill speed — not as fast as Dylox for grubs
- Must store above 32°F — can't freeze

Cons
- Some bottles have defective nozzles — check reviews
- Only 5,120 sq ft per bottle — buy multiple for large lawns
- More expensive per treatment than concentrates
- Needs monthly reapplication
BioAdvanced uses a dual-action formula combining fast-acting zeta-cypermethrin with long-lasting bifenthrin. The granules are specially formulated to be carried into fire ant mounds by worker ants, killing the colony from within rather than just the surface. For mound treatment, apply 2–4 tablespoons per mound and do not water in — the ants must carry the granules inside. Mounds are typically dead within 24–48 hours.
What it kills: Fire ants, fleas, ticks, chinch bugs, ants, crickets, armyworms, sod webworms, mole crickets, grubs.
Do NOT water in when treating fire ant mounds — the ants must carry the granules inside. For broadcast lawn treatment, DO water in with 0.25 inches of water. Read the label carefully.
Pros
- Excellent fire ant colony elimination
- 24-hour mound kill
- 3 months prevention — stops re-colonization
- Dual active ingredients for broad-spectrum control
- Affordable for fire ant control
Cons
- Different watering instructions depending on target pest — easy to confuse
- Smaller bag size — only 5,000 sq ft per 10 lb bag
- Not as fast as Dylox for grubs
Buying Guide: How to Choose the Right Lawn Insecticide
Types of Insecticides
Granular — Best for broad coverage and soil-dwelling pests. Apply with a spreader and water in. Good for preventative treatments. Longer residual than most liquids. Examples: Dylox 6.2, Talstar XTRA, BioAdvanced.
Liquid Concentrates — Best for targeted treatments, quick knockdown, and perimeter barriers. Usually the most economical option. Requires mixing and a sprayer. Examples: Bifen IT, Taurus SC, Permethrin SFR, Demand CS.
Ready-to-Use (RTU) — Best for convenience and small areas. No mixing or equipment needed — attach to hose and spray. More expensive per treatment. Example: Spectracide Triazicide.
Understanding Active Ingredients
| Type | Examples | Speed | Residual | Best For |
|---|---|---|---|---|
| Pyrethroids | Bifenthrin, Permethrin, Lambda-cyhalothrin | Fast (24–72h) | 30–90 days | Broad-spectrum control |
| Organophosphates | Trichlorfon (Dylox) | Very fast (24h) | Short (48h) | Emergency grub control |
| Phenylpyrazoles | Fipronil (Taurus SC) | Slow (7–90d) | Excellent (90d+) | Colony elimination |
When to Apply
Spring (March–May): Preventative grub control, chinch bugs, ants. Best products: preventative grub treatments, Bifen IT for perimeter.
Summer (June–August): Active infestations, mosquitoes, ticks, fleas. Best products: Demand CS (mosquitoes), Permethrin (ticks), Dylox (grubs).
Fall (September–November): Late-season grubs, preventative treatments. Best products: Dylox (curative), Talstar XTRA (preventative).
Winter: Focus on indoor perimeter maintenance with limited outdoor applications.
Always read the full label before use. Keep children and pets off treated areas until dry (2–24 hours depending on product). Don't apply near water sources or flowering plants. Wear gloves and long sleeves during application. Never apply before rain — allow 2–24 hours drying time.
Frequently Asked Questions
Preventative control: Apply in late spring (May–June) before pests become active. Ideal for grubs, chinch bugs, and other seasonal pests.
Curative control: Apply when you notice damage or see pests. Summer and early fall are common for active infestations.
Best time of day: Early morning (6–10 AM) or late evening (6–8 PM) when temperatures are cooler and winds are calm.
It depends on the product type. Granular preventatives: once per season (spring or fall). Liquid residuals: every 30–90 days depending on product. Curative treatments: once, with possible reapplication in 14 days. RTU products: every 30 days during active pest season. Always follow label instructions for specific reapplication intervals.
Yes, when used properly. Most products are safe once fully dry (2–24 hours after application). Always keep pets and children off treated areas until completely dry. Products like Demand CS and Bifen IT have low mammalian toxicity and are considered safe once the spray has dried. Follow all label safety precautions.
Granular: Easier to apply with a spreader, better for soil-dwelling pests (grubs), longer residual (30–90 days), must be watered in, less precise targeting.
Liquid: Faster acting, better for surface pests and foliage, more precise application, requires mixing and a sprayer, better for perimeter treatments and hard-to-reach areas.
The best choice depends on your target pest, area size, available equipment, and personal preference.
Most insecticides can harm bees and butterflies when wet. To minimize harm: don't spray flowering plants, apply in early morning or evening when pollinators aren't active, use targeted spot treatments instead of broadcast applications, and choose products with shorter residuals. Dylox has a short residual (48 hours) which reduces long-term impact. Granular products watered into soil are generally safer for pollinators than foliage sprays.
Must water in: Dylox 6.2 (critical — won't work without it), Talstar XTRA, BioAdvanced for general pests, most granular products targeting grubs.
Do NOT water in: Taurus SC for fire ants, BioAdvanced for fire ant mounds, most liquid perimeter treatments.
Optional: Bifen IT (helps but not required), Spectracide RTU (improves soil pest results).
Always check the product label — it will specify exactly whether watering is required, optional, or prohibited.
No — avoid application before rain. Most products need 2–24 hours to dry or be absorbed before rain hits. Rain will wash away product before it works, waste money, and create runoff that can harm waterways. Check the 48-hour weather forecast before applying. Best practice: apply when no rain is expected for at least 24 hours.
For better value: Bifen IT — treats 44,000 sq ft vs 5,120 sq ft for about the same bottle price. Professional-grade effectiveness.
For faster results on grubs: Dylox 6.2 — works in 24 hours.
For convenience: Spectracide is actually hard to beat — it's ready to spray with no mixing. But Bifen IT offers significantly better value and effectiveness if you're willing to mix.
All of the following are safe for grass when applied at label rates:
- Dylox 6.2 — fast curative treatment (works in 24 hours)
- Talstar XTRA — preventative + curative
- BioAdvanced 24-Hour Grub Killer — quick action
- Merit (imidacloprid) — preventative only, must apply before grubs hatch
Apply when grubs are small (late summer), water in thoroughly (0.5 inches), and use appropriate spreader settings. Don't overapply.
