The only reliable method of protection against mosquitoes is to use one of the effective repellents that are sold over the counter. Mosquito repellent contains some smells that confuse the mosquitoes. The first thing a mosquito does when looking for prey is to see if there are any animals or people in the vicinity.
唯一有效的免于蚊虫叮咬的方法是使用在柜台处买来的对付蚊虫的强效防蚊剂。防蚊剂包含了一些让蚊子产生混淆的气味。蚊子寻找猎物要做的第一件事是查看附近有没有动物和人。
When the mosquito comes closer, it uses smell, heat and carbon dioxide to decide whether to bite. But if it is confused by a repellent, it will never get that far, says Jensen. However, even repellents do not provide complete protection against the persistent insects.
当蚊子靠近时,它会根据气味、热量和二氧化碳来决定是不是要叮咬。但如果它被防虫剂弄迷糊了,它不会轻率行动。詹森说。然而,即使是防虫剂也没有为人们提供保护,让我们完全免于蚊虫频繁袭击。
Repellents reduce the number of bites by as much as 70 percent. Thats all well and good, but youll still get bitten once in a while.
防虫剂可以减少蚊虫的叮咬次数,最多能降低70%。这样的效果也算很不错了,但你仍会时不时地被咬上一口。
