托姆和普林西比民主共和国于2004年开始在全国范围内每年一次使用拟除虫菊酯-氯氰菊酯进行室内滞留喷洒，剂量为50毫克/平方米。IRS的接受率很高，住宅和外屋的接受率从82%到95%不等。在第一个IRS周期前后对9岁以下儿童进行的流行病学调查显示，疟疾发病率迅速下降。在第一次IRS后12个月，所有地区疟疾寄生虫血症的总体流行率从20.1%降至2.8%，在第二次IRS后8个月达到0.7%。长时间的杀虫持久性被发现在木材上比水泥与氯氰菊酯。
A nationwide yearly cycle of indoor residual spraying (IRS) with a pyrethroid, alphacypermethrin, at a dosage of 50 mg/m(2) was instituted in 2004 in the Democratic Republic of Sao Tome and Principe. Rates of IRS acceptance were high, varying from 82% to 95% for dwellings and outhouses. Epidemiologic surveys of the children < 9 years of age before and after the first IRS cycle revealed a rapid reduction in malaria. Overall prevalence of malaria parasitemia for all districts was lowered from 20.1% to 2.8% at 12 months after the first IRS and reached 0.7% at 8 months after the second IRS. Longer insecticidal persistence was found on wood than on cement with alphacypermethrin.
