Is dinotefuran-containing household insecticide spray effective against shore flies?

Is dinotefuran-containing household insecticide spray effective against shore flies? Dinotefuran spray is effective against adult shore flies and is suitable for use in damp environments, making it an effective tool for eliminating adult shore flies.

Application method

• Spray on bathroom walls, tile joints, under sinks, and around pot trays.
• Focus on damp transition zones where shore flies rest and crawl — drain edges, tile gaps, and countertop-wall junctions.
• Spray until the surface is slightly damp; do not over-apply.
• Wait for the spray to dry; the invisible film becomes effective and lasts 2-4 weeks.

Mode of action

• Shore flies crawling on damp surfaces contact the dried dinotefuran film.
• The insecticide penetrates through the body wall (contact action) and acts on the nervous system.
• Within hours of contact, they gradually lose activity and die.
• Non-repellent — shore flies do not detect the insecticide and do not avoid it, resulting in high kill rates.

Spray location precautions

• Spray on dry areas around damp surfaces, not directly into water (the insecticide is diluted and ineffective in water).
• The insecticide works only after drying; wait about 30 minutes.
• Reapply if the area is washed or mopped.
• Cover fish tanks when spraying — dinotefuran is toxic to aquatic life.
• Keep pets (cats, dogs) away until the spray is dry.

Combine with dehumidification

• Dinotefuran kills adults, addressing the immediate problem of flying midges.
• Removing standing water cuts off larval breeding, solving the root problem — no standing water means no next generation.
• Combination: 1-2 spray applications + keeping dry for 1-2 weeks = complete elimination of shore flies.
