⚙️ How It Works
Kaolin clay creates a physical barrier that deters and irritates pest insects — doesn't kill, makes plant inhospitable for landing and egg-laying. Surround WP is standard for commercial pear and apple production.
⚗️ Mixing & Application
Surround WP: 25 lb per 100 gallons. Small scale: 3 cups per gallon. Apply 3–5 coats to build barrier. Requires constant agitation — clay settles quickly.
Example

❓ Frequently Asked Questions
Q: Is kaolin clay safe for pets?
Follow the product label. Keep pets out of treated areas until completely dried (2–4 hours for sprays). Once dry, treated surfaces pose minimal risk to dogs and cats.
Q: Can I use kaolin clay indoors?
Check the specific product label — formulations vary. Baits and dusts often have indoor labeling; concentrates and granulars are typically outdoor.
Q: How long does kaolin clay last after application?
Residual varies by formulation, surface type, weather, and UV exposure. Indoor applications last longer than outdoor. Check the product label for re-application intervals.
Q: What should I do if exposed?
Remove contaminated clothing, wash skin with soap and water. For eye contact, rinse 15–20 minutes. For ingestion or severe symptoms, call Poison Control (1-800-222-1222). Have the product label available.
