PRONet Duo® is a revolutionary insecticide treated net (ITN) by V.K.A. Polymers, combining two active ingredients—chlorfenapyr and bifenthrin—to combat pyrethroid-resistant mosquito populations. WHO pre-qualified and backed by extensive field data, PRONet Duo® sets a new standard in malaria prevention through innovative malaria vector control.
Incorporates chlorfenapyr and bifenthrin to target resistant mosquito strains more effectively.
Demonstrated superior mosquito mortality and blood-feeding prevention in hut trials.
Engineered with polyethylene monofilament yarn for durability and insecticidal longevity.
Maintains efficacy even after 20 washes, surpassing WHO standards.
Combines personal safety with mass effect, reducing transmission at scale.

| Study | Result |
|---|---|
| Acute Oral Toxicity Study in Wistar Rats | Classified as Category 5 or unclassified under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). LD50 value > 2000 to ≤ 5000 mg/kg body weight, with an LD50 cut-off value of 5000 mg/kg. |
| Acute Dermal Toxicity Study in Wistar Rats | LD50 value >2000 mg/kg body weight. Classified as Category 5 or unclassified under GHS. |
| Acute Inhalation Toxicity Study in Wistar Rats | Classified as Category 5 or unclassified under GHS. |
| Acute Dermal Irritation/Corrosion Study in Rabbits | Tested on New Zealand White Rabbits. PRONet Duo® was found to be non-irritant under experimental conditions. |
| Eye Irritation/Serious Eye Damage study in New Zealand White Rabbits | Tested on New Zealand White Rabbits. PRONet Duo® is a non-irritant to the eye of New Zealand white rabbit. |
| Skin sensitization Study in Guinea Pigs | Non Sensitizer to the skin of the guinea pigs. |
Bifenthrin acts quickly on contact, while chlorfenapyr disrupts mosquito energy metabolism, ensuring double-layered defense.
Higher insecticide surface concentration allows enhanced mosquito exposure and kill-rate.
Designed to tackle pyrethroid resistance by utilizing two unrelated modes of action.

| Non-Irritant | Bifenthrin does not cause irritation to the skin and eyes, ensuring safer use for individuals. |
| Superior Residual Activity | One of the most effective properties to handle and eliminate resistant malaria vectors. |
| Highly Effective | Designed to collapse even the most resilient mosquito populations. |
| Greater Stability | Bifenthrin offers improved stability than other pyrethroids, enhancing its longevity in real-world conditions. |
| Enhanced Molecular Permeability | Molecular structure allows higher uptake and penetration for faster and deeper action. |
| Enzyme Resistance | Less susceptible to degradation by mosquito detoxification enzymes. |
| Slower Enzymatic Breakdown | Decomposes more slowly when exposed to mosquito resistance mechanisms, extending its action time. |
| Superior Photostability | Does not undergo rapid decomposition by light (photolysis), enabling better photostability of the ingredient in PRONet Duo® in regular use. |
