Can dinotefuran-containing household insecticide spray control termites?

Can dinotefuran-containing household insecticide spray control termites? Sprays containing dinotefuran are highly effective against termites. Dinotefuran is a third-generation neonicotinoid insecticide with a different mode of action from traditional pyrethroids.

Advantages of dinotefuran-containing sprays

1. Dual contact and stomach action, termites die from either contact with the insecticide or ingesting treated wood.
2. Transfer effect, termites have grooming and trophallaxis (mutual feeding) habits; workers that contact the insecticide carry it back to the colony, spreading it to other members, including the queen and larvae.
3. No repellency, unlike pyrethroids, dinotefuran does not repel termites; they do not avoid treated areas, ensuring the insecticide reaches them.
4. Long residual effect, in dry indoor environments, the residue remains effective for about 2-4 weeks.

Correct application method

• Inject the insecticide into mud tubes, swarm holes, and drill holes (spaced 20-30 cm apart) in damaged wood. Termites moving through these areas will contact the insecticide and carry it back to the nest.
• Spray around wall bases and door frames to create a 10-15 cm wide residual barrier.
• Soil treatment: dig a shallow trench (5-10 cm deep) along the foundation and apply the insecticide to the soil.

Speed of action

Termites that contact dinotefuran residue typically die within 2-3 days. Through the transfer effect, most colony members can be affected within 1-2 weeks.

Precautions

For established large colonies, multiple treatments are needed. One treatment is unlikely to eliminate the entire colony. Check every 1-2 weeks and reapply if termite activity is seen. If the colony is large or in a hard-to-reach location, call a professional termite company.
