Instead, we prevent pests coming in and we use beneficial insects like ladybugs to eat them if they do.

我们还可以防止害虫入侵，如果害虫来了，我们会用瓢虫，这样益虫吃掉它们。

Again, not such a great idea, sorry! That's because bug zappers aren't really that amazing at killing mosquitoes, but they do end up killing a bunch of beneficial insects and that aren't seen as pests.

这个点子也不好，抱歉，这是因为灭虫器的杀蚊效果并不是很好，但是它们会杀死很多并不被视为害虫的有益昆虫。

Instead of a reactive approach to soil fertility or pests, the organic approach is a proactive system that favors soil life and fertility, beneficial insects, and natural predators of pests such as bats.

有机方法不是对土壤肥力或害虫的反应性方法，而是一个有利于土壤生命和肥力、有益昆虫和蝙蝠等害虫天敌的主动系统。
