Jason used Fox Farm "Don't Bug Me" (pyrethrin) on Cape sundew crowns and it burned new and mature leaves. He asks if this is normal and what safe brand to use.
Jeff Dallas says he's heard similar reports. Usually the carrier (surfactant, wetting agent) causes phytotoxicity, not the pyrethrin itself. It's product-specific. Always test new products on 1-2 plants first. Check labels for sensitive species listings—if carnivorous plants are listed as sensitive, use extreme caution.
They use Bayer Rose & Flower spray (imidacloprid systemic). Low odor, lasts ~1 month, never caused harm. Link provided.
Good Growing!
