All WSEBs were treated by soaking in aqueous suspensions of the insecticides, BA, or both and then drying in the shade.
After mosquito collection each morning, each pair of men was responsible only for installing the set of WSEBs assigned to their hut that evening and for removing that set from the hut it had been fitted to the previous night.
Overall, insecticide-treated WSEBs either matched or were superior to IRS when used against An.
WSEBs with intermediate or high doses of pirimiphos-methyl killed more An.
Adding BA had no effect on the mortality rates for pirimiphos -methyl--treated WSEBs for An.
Although WSEBs had higher efficacy than IRS against early exiting An.
These WSEBs are an experimental prototype that were evaluated in the necessarily homogenous and controlled environment of experimental huts.
In comparison, a house of equivalent size with WSEBs installed could be treated with the same insecticide at the same dose per square meter of treated netting for only $2.15.
Although handling insecticides is always associated with some risks, and protective clothing, eyewear, and a breathing apparatus might be required, WSEBs may be impregnated by simply dipping them in an aqueous suspension, similarly to bed nets.
The observation that supplementing pirimiphos-methyl --treated WSEBs with the irritant pyrethroid lambda-cyhalothrin reduced mortality rates for An.
