What Hi‑Yield 38 Plus (31333) Is and Who It’s For
Hi‑Yield 38 Plus (31333) is a concentrated, outdoor liquid insecticide containing 38% permethrin formulated for turf, ornamental beds, and perimeter barrier treatments; you mix it with water and apply it with a tank or power sprayer or in spot treatments. You’ll find it’s intended for outdoor uses only, with label-directed dilution and application rates. Garden professionals will appreciate concentrated formulation and compatibility with common spray equipment; seasonal homeowners will value flexible spot treatments and one-gallon sizing. You must follow label precautions, avoid indoor use, and consult the full label for target insects, safety, and site-specific application instructions. Many homeowners who enjoy outdoor spaces also invest in landscaping solutions like channel drains to protect and enhance their yards beautiful home landscapes.
Performance Summary: Which Pests It Controls and How Well It Works
Building on its intended uses and application methods, this concentrate delivers broad-spectrum control of many outdoor nuisance and turf pests through contact and residual activity. You’ll find reliable knockdown of mosquitoes, with mosquito efficacy dependent on application rate and coverage; treatments reduce adult populations and limit re-infestation when retreatment intervals are observed. Ant control is effective for surface-foraging species but results vary for deep-nesting colonies and may require integrated baiting. Additional labeled targets include beetles, cockroaches, spiders and caterpillars, all showing rapid mortality on contact. For consistent results, follow label rates, timing, and environmental precautions. As part of responsible yard care, homeowners should pair treatments with proper sanitation to minimize pest habitat and reduce the need for repeat applications.
How to Mix and Apply Outdoors (Lawns, Beds, Barrier Treatments)
When treating lawns, ornamental beds, or creating perimeter barrier bands, mix the 38% permethrin concentrate with water per the label-specified rate for your application method and target pest, and apply with a calibrated tank or power sprayer to guarantee uniform coverage and correct delivery volume. Measure mix ratios precisely—use graduated containers and record volumes for repeatable results. Apply during calm weather and cooler parts of day; plan application timing to target peak pest activity and minimize drift. Sweep patterns to overlap slightly for continuous coverage, avoid runoff, and re-treat at label-allowed intervals to maintain an effective barrier for your landscape. For best results when applying to turf and beds, choose spray nozzles designed for even droplet distribution and uniform coverage.
Safety, Restrictions, and Label Compliance You Must Follow
Because this product is a concentrated outdoor insecticide, you must follow label directions and legal restrictions precisely to protect people, non‑target organisms, and the environment. You’ll wear required personal protective equipment—chemical-resistant gloves, long sleeves, eye protection, and a respirator if label specifies—during mixing, loading, and application. You must not apply near aquatic habitats, bees, or on impervious surfaces that increase environmental run off; maintain buffer zones and avoid application before heavy rain. Store and dispose of diluted or unused product per label. Record applications, observe reentry intervals, and comply with local regulations to guarantee legal and safe use. Homeowners should also consider using lawn and landscape tools designed for safe application to minimize over-application and drift.
Buying Checklist: Size, Equipment, Cost, and When to Choose This Product
If you need broad, long‑lasting outdoor knockdown and residual control, choose the 1‑gallon Hi‑Yield 38 Plus concentrate for yard‑scale treatments where you can mix and apply with proper equipment. You’ll value gallon comparisons when matching coverage to property size: one gallon (128 fl oz) treats multiple barrier bands depending on dilution. Use a tank or power sprayer, calibrated for labeled rates; handheld pumps suit spot work. Factor item weight (7.9 lb), personal protective equipment, and disposal. Consider cost per treated area versus smaller containers and professional services. Prioritize seasonal planning for peak pest windows and legal label compliance. For homeowners managing irrigation and landscaping, integrating zone valve maintenance can help protect treated areas and prevent runoff into outdoor spaces.
Some Questions Answered
Can Permethrin Wash off After Heavy Rain and How Soon Is Retreatment Needed?
Yes — heavy rain can reduce surface residues; wash off timing depends on rainfall intensity and drying time, often within 24–48 hours. You’ll need to inspect treated areas after storms; reapply if visible loss occurred. Follow label retreatment interval, typically 7–14 days for barrier or spot treatments, or as label specifies for your use. Stay within safety precautions and don’t retreat sooner than the specified retreatment interval.
Is This Product Harmful to Pollinators Like Bees if Applied Near Flowers?
Yes — permethrin is toxic to bees and can cause foraging disruption if applied near flowers. You should avoid spraying bloom periods, apply only to non-flowering vegetation, and use targeted band or spot treatments away from pollinator activity. Read label restrictions and buffer zones, time applications for evening when bees are less active, and consider alternative controls or professional advice to protect pollinators and maintain community stewardship of beneficial insects.
Can I Mix Hi‑Yield 38 Plus With Other Pesticides or Fertilizers?
You shouldn’t assume compatibility; always check label compatibility before tank mixing. You’re allowed to tank mix only if the other product’s label and this product’s label explicitly permit it and provide mixing instructions. You’ll perform a jar test for physical compatibility and follow rate, timing, and safety directions. If labels conflict or are silent, don’t mix; instead, sequence applications per label guidance or consult the manufacturer for technical confirmation.
How Should I Store Leftover Concentrate Safely Long‑Term?
Store leftover concentrate in its original, tightly sealed container in a cool, dry, well-ventilated area away from heat or direct sunlight. Label the container with date and contents, keep it off the ground on a secondary containment tray, and maintain proper ventilation to avoid fume buildup. Use childproof storage—locked cabinet or secured chemical locker—and keep an accessible inventory log so everyone in your group knows it’s present and how to handle emergencies.
Are There Residential Pet Reentry Time Guidelines After Treatment?
Yes — you should restrict pet reentry until treated areas are dry and ventilated; typical outdoor reentry is when spray residues have dried (usually 2–4 hours). To minimize pet exposure, keep animals off treated turf, beds, and barrier bands until surfaces are dry and follow label-specific intervals. You’ll also clean pet bedding and avoid contact with wet surfaces; always consult label for precise reentry and exposure-reduction instructions.
