Can dinotefuran-containing household insecticide spray kill carpet beetles?

Can dinotefuran-containing household insecticide spray kill carpet beetles? Dinotefuran spray is effective against carpet beetles, including both adults and larvae, with good contact action.

Effectiveness against carpet beetles

When adult and larval carpet beetles crawl over the dinotefuran film, the insecticide is absorbed through the body wall, disrupts the nervous system, and kills them within hours. Because carpet beetle larvae are active crawlers in search of food, contact rates are high.

Key spraying areas

• Baseboards and floor cracks — larvae often crawl along walls.
• Wardrobe bottom gaps and shelf joints.
• Carpet edges and underneath.
• Storage cabinet corners and shelves.
• Sofa and bed edges.
• Around radiators (carpet beetles prefer warm areas).

Application method

1. Spray dinotefuran-containing insecticide evenly on target surfaces.
2. Spray until slightly damp — do not over-apply.
3. Once dry, the film is colorless and odorless.
4. Beetles die upon contact when crawling over the film.
5. Residual effect lasts 2-4 weeks on dry indoor surfaces.

Precautions

• Avoid spraying on clothing and food.
• Do not spray heavily on surfaces frequently touched by children and pets.
• Remove clothing from wardrobes before spraying; return them after the spray is dry.
• For larvae deep inside clothing, surface spraying alone is insufficient; combine with washing and sun exposure.

Integrated advice Dinotefuran spray works well against carpet beetles, but it should be combined with environmental management (cleaning, removing food sources, sealed storage) for a fundamental solution.
