🔬 How It Works
Gentrol contains hydroprene, a juvenile hormone analog (JHA) IGR. Unlike contact insecticides that kill on contact, hydroprene works by mimicking the natural juvenile hormone that prevents insect larvae from maturing into reproductive adults.
Effect on cockroaches: Nymphs exposed to hydroprene develop into sterile adults with visible deformities (curled wing stubs visible in German cockroaches) or fail to complete metamorphosis. They cannot reproduce. This breaks the breeding cycle without directly killing insects — it's best used in combination with gel bait or sprays for both immediate and long-term control.
IGR comparison: Methoprene (Precor) = flea-specific. Pyriproxyfen (Nylar) = broad IGR including fleas + cockroaches. Hydroprene (Gentrol) = cockroach + stored product insects. These are not interchangeable.
⚗️ Mixing & Application Rates
Gentrol concentrate is diluted in water and applied as a residual spray.
⚠️ Safety & Precautions
- Very low mammalian toxicity — juvenile hormone analogs are highly specific to insects
- No direct kill — must be combined with contact insecticide for comprehensive cockroach control
- Do not use as a sole treatment for active infestations
- Safe to use in food handling areas on non-food-contact surfaces per label
