Is dinotefuran-containing household insecticide spray effective against silverfish?

Is dinotefuran-containing household insecticide spray effective against silverfish? Dinotefuran spray is highly effective against silverfish and is very well-suited to their control characteristics.

Why is dinotefuran effective against silverfish?

Silverfish are nocturnal — they hide in crevices during the day and come out at night to feed. Dinotefuran's "residual spraying" strategy is ideal for controlling them:

1. Apply the spray on surfaces where silverfish move during the day (wall bases, cabinet bottoms, baseboards).
2. The spray dries to form a colorless, odorless film.
3. At night, silverfish come out and crawl over the treated surface.
4. The insecticide penetrates through the body wall of their feet and abdomen, acting on the nervous system.
5. Silverfish die within hours to 1-2 days of contact.

Suitable spray locations

6. Baseboards and corners — silverfish's main travel routes along walls.
7. Cabinet bottoms and back panel gaps — where they hide during the day and emerge at night.
8. Bookcase backs and bottoms — activity areas among books.
9. Door and window frames — entry routes from outdoors.
10. Floor cracks — especially gaps between wood floors and tiles.

Application method

6. Clean the target area first; vacuum to remove dust and debris.
7. Spray dinotefuran-containing household insecticide evenly on dry surfaces from a distance of 20-30 cm.
8. Keep surfaces slightly damp; do not over-apply.
9. Wait for the spray to dry completely (about 1-2 hours).

Precautions

5. Do not spray on books, paper, or clothing.
6. Do not spray on food or utensils.
7. Keep pets and children away during spraying.
8. Once dry, it is safe for humans and pets.
9. If there are many silverfish, reapply after 2 weeks.

Combined with dehumidification for better results

Silverfish prefer damp environments. Combining spraying with dehumidification (humidity below 50%) improves results. Dinotefuran film lasts about 2-4 weeks, continuously killing newly hatched or newly introduced silverfish.
