Treated apparel that has been impregnated with either insecticidal or repelling substances can be used in addition to skin repellents to increase the personal bite protection. The efficacy of treated surfaces can be evaluated in different ways: The bite preventing (repelling) effect of the textile can be measured on the one hand, while the neurotoxic (insecticidal) effects can be documented on the other.
The following methods are suited for testing treated textile materials
- BG-Cage test (bite prevention)
- WHO-Cone or WHO-Tube tests (insecticidal effects)
- Tests according to German Armed Forces Specification TL 8305-0331 (insecticidal effects)
- Exposition tests in petri dishes (insecticidal effects)
