Delta S is a concentrated, solvent-free liquid insecticide based on deltamethrin with tetramethrin and the synergist piperonyl butoxide. It combines fast knock-down with long-lasting residual action and is especially effective against crawling and flying insects as well as bed bugs.
Why choose Delta S
- Fast knock-down + long-term action: deltamethrin with tetramethrin and PBO synergist.
- Solvent-free (flow formula): low odor and gentle on materials.
- Effective against bed bugs (Cimex lectularius) as well as crawling and flying insects.
- Versatile: also suitable for green spaces and use with thermal foggers (hot foggers).
- For professionals: for commercial use only.
Target organisms
Crawling insects (ants, fleas, cockroaches), flying insects (flies, midges, tiger mosquitoes, mosquitoes), and bed bugs (Cimex lectularius).
Application
Dilute Delta S with water and apply to infested surfaces, runways, and hiding places; also suitable for treating green spaces and for use in thermal foggers. Read the label and safety data sheet before use.
Good to know
- Synergy against resistance: the synergist piperonyl butoxide (PBO) inhibits the insects’ detoxification enzymes (cytochrome P450) and thereby supports the effect of deltamethrin and tetramethrin – even where insects have developed metabolic resistance.
- Odorless & solvent-free: the flow formula is suitable for occupied indoor spaces and sensitive areas.
- Fast knock-down + residual action: tetramethrin provides the immediate effect, deltamethrin the lasting one.
