How do I know which concentration to buy?

Consumer (RTU/concentrate) products are formulated for homeowner application rates. Professional-grade concentrates require accurate dilution — mistakes in either direction reduce effectiveness or create safety hazards. If you're new to pesticide application, start with ready-to-use formulations and work up to concentrates once you understand mixing and rates.

Can I mix this with other pesticides?

Tank mixing is common in professional applications but requires compatibility testing and label compliance. Never mix pesticides unless both labels permit it. One safe and effective combination: pair an adulticide with an IGR — they attack different life stages and don't interfere with each other.

How long does the treatment remain effective?

Residual activity depends on formulation, surface, UV exposure, and temperature. Micro-encapsulated formulations last longest (4–12 weeks). Wettable powders and emulsifiable concentrates typically last 2–6 weeks outdoors. Indoor applications on non-porous surfaces can persist significantly longer.

Is this product safe for use around pets and children?

All pesticides have some level of toxicity — 'safe' means used correctly according to the label. Keep children and pets out of treated areas until completely dry (minimum 2–4 hours for most sprays). For households with infants or chemically sensitive individuals, discuss low-exposure options (baits, dusts, IGRs) with a pest management professional.

🎯 What It Kills

✓ Scale (all stages)✓ Spider Mites✓ Aphids✓ Whiteflies✓ Psyllids✓ Adelgids✓ Mealybugs✓ Overwintering Mite Eggs

⚙️ How It Works

Horticultural oils kill by suffocating insects — oil coats and blocks spiracles (breathing pores). Also ovicidal. Dormant oil in late winter kills overwintering mite eggs. No resistance possible — purely mechanical.

⚗️ Mixing & Application

Growing season: 1–2% solution (1.3–2.5 fl oz per gallon). Dormant season: 2–3% solution. Must contact pest — no residual.
