• Non-toxic to humans, pets, environment
• Apply to active areas

Option 2: Pyrethrum

• Chrysanthemum-derived; broad-spectrum
• Non-toxic to mammals; degrades quickly in sunlight
• Effective against wide insect range

Sanitation Notes

• Clean recycling bin thoroughly; ensure tight-fitting lid
• Remove decaying organic matter from rock yard
• Improve drainage to reduce moist habitats

Treat larvae directly; fix conditions attracting them.
