How effective is dinotefuran-containing household insecticide spray against cockroaches?
How effective is dinotefuran-containing household insecticide spray against cockroaches? Dinotefuran spray is highly effective against cockroaches, and they do not develop resistance to it nor actively avoid it.
Why is it effective?
- Dual action: both contact and stomach action — cockroaches are poisoned by crawling over the film and also by ingesting the insecticide during grooming.
- Secondary transmission: poisoned cockroaches return to the nest and spread the insecticide to others through physical contact and cannibalism.
- Long residual effect: one application lasts several weeks and does not lose effectiveness when wet.
- No resistance: traditional pyrethroid insecticides and bait gels can lead to resistance; dinotefuran has a different mode of action, which cockroaches cannot detect or develop resistance to.
- Fast-acting: cockroaches die within 24 hours of contacting the film; direct spraying kills within minutes.
Correct application method
- Spray on routes cockroaches frequently travel: cabinet corners, around pipes, baseboards, and behind refrigerators.
- Allow the spray to dry naturally — the film is only effective after drying completely.
- Do not spray on food or utensils, nor near water sources.
- One application typically lasts 2-4 weeks; a convenient modern method for cockroach control.
Precautions
Keep pets and children away during spraying; allow to dry completely before normal activities resume.
