sand flies and a host of other arthropods are prevented from biting a great percentage of the

exposed part of the body. The usage of repellent bedsheets and pillow-cases reduces the

colonization of bed bugs which are difficult to get rid of once the presence is established.

Running of efficacy tests to measure entomological repellency and persistency is highly

recommended. Measurement of textile repellent efficacy requires a standard cage test with

a solid protocol to ensure that proper test results are obtained. From repellent treated textile,

the approaches to ward off arthropods, vectors of disease is promising. (Figure 3.12).

CONCLUSION NOTE

The proven standard cage test method is the necessary step, for repellent textile efficacy

approval and the determination of level of persistence (Figures:3.13 and 3.14).
