Knockdown Testing


Knockdown, or “KD,” testing is a widely accepted scientific laboratory methodology for determining the efficacy of insect repellent-treated textile products. Many recognized agencies utilize KD testing for this purpose, including the World Health Organization (WHO), the U.S. Centers for Disease Control and Prevention (CDC), and the U.S. Department of Agriculture (USDA). One of the advantages of KD testing is that no human subjects are exposed to insects. A repellent-treated textile sample is placed in an enclosed space containing insects for a specified time period, after which the sample is removed and the insects’ reaction is documented. 
 
 
Average knockdown is determined using at least 10 replicates of a particular species and wash combination.

What are the benefits of Insect Shield vs. other forms of insect protection?
One advantage of using Insect Shield Apparel and Gear is that the repellency is long lasting, requiring no re-application. This convenience factor can be significant for many outdoor pursuits. Insect Shield protection is also odorless and invisible, and, unlike traditional insect repellents, the repellency is near your skin, instead of on it, which can help alleviate concerns about overuse or misuse of insect repellent.
