An experiment was carried out in South Bohemia, in which 10% water emulsion of diethyltoluamide was used as repellent against bloodsucking Diptera to protect pastured dairy cattle. The repellent was applied by means of a spraying frame and was effective for 30-36 hours. Seven mosquito species and 18 horsefly species were observed to be attacking the cattle. The average number being 120-300 mosquitoes and 50 horseflies per hour, the milking qualities in the cattle decreased by 6.2%, the milk fat content by 11.8%. After converting to milk with average fat content of 4%, the difference in milking qualities between treated and untreated animals was 9.7%.
在南波希米亚进行了一项实验，其中使用10%的二乙甲苯酰胺水乳剂作为驱避剂来抵御吸血双翅目昆虫，以保护放牧的奶牛。该驱避剂通过喷雾架施用，有效期为30至36小时。观察到有7种蚊子和18种马蝇攻击奶牛。平均每小时有120至300只蚊子和50只马蝇，奶牛的产奶质量下降了6.2%，乳脂含量下降了11.8%。换算成平均脂肪含量为4%的牛奶后，处理过和未处理过的动物之间的产奶质量差异为9.7%。
