使用实验小屋进行了一项试验，以确定蚊子是否会进入人们使用未经处理的蚊帐的邻近住宅，因为人们睡在浸有氯菊酯的蚊帐下。在冈比亚的旱季，在六个实验小屋中，每个小屋都有一个人在蚊帐下睡了六个星期。其中一顶蚊帐浸有氯菊酯，其他五顶蚊帐未经处理。试验的设计是基于一系列的拉丁方块，因此在不同的夜晚，人和网都在小屋之间轮换。在试验结束时，每个人都睡在每个小屋的每个网下。每天早上从小屋收集的蚊子用于估计夜间进入每间小屋的蚊子总数。少量冈比亚按蚊Giles（广义）、A. pharoensis Theobald和Mansonia spp.进入一个小屋与浸渍蚊帐比那些未经处理的蚊帐。然而，没有证据表明，阻止蚊子进入装有经处理蚊帐的小屋的蚊子会进入邻近装有未经处理蚊帐的小屋。因此，在大多数人使用浸渍蚊帐的社区中，使用未经处理的蚊帐的人似乎不太可能比每个人都受到更多的叮咬。有一个未经处理的网。然而，蚊子对浸有氯菊酯的蚊帐的反应被发现取决于它们的种类和营养条件，因为A。rufipes Gough、带状库蚊属（Culex spp.）和非人血喂养的A.冈比亚人（广义上说）可自由进入带处理过的蚊帐的棚屋。
A trial was carried out using experimental huts to determine whether mosquitoes deterred from entering a building where a person slept under a permethrin-impregnated bednet would enter neighbouring dwellings where people used untreated nets. In each of the six experimental huts a man slept under a bednet for six weeks during the dry season in The Gambia. One bednet was impregnated with permethrin, the other five nets were untreated. The design of the trial was based on a series of Latin squares, so that both men and nets were rotated between huts on different nights. At the end of the trial each man had slept under each net in each hut. Mosquitoes collected from the huts each morning were used to estimate the total number of mosquitoes which had entered each hut during the night. Fewer Anopheles gambiae Giles (sensu lato), A. pharoensis Theobald and Mansonia spp. entered a hut with an impregnated bednet than those with untreated nets. However, there was no evidence that mosquitoes deterred from entering a hut with a treated net entered neighbouring huts with untreated nets. Thus it appears unlikely that people using untreated bednets in a community where most use impregnated nets would receive more bites than if everyone. had an untreated net. However, the responses of mosquitoes to permethrin-impregnated bednets were found to depend both upon their species and nutritional condition since A. rufipes Gough, banded Culex spp. and non-human bloodfed A. gambiae (sensu lato) freely entered huts with a treated net.
