草地还是菜地?
草地的话,就买专门的杀虫剂,HD啦陋室啦都有的。
菜地用那种生物制剂,Live Beneficial Nematodes。
我两种都用过,最后也搞不清是哪种起的作用,反正现在菜地里没有grub了。

Imidacloprid is a systemic insecticide which acts as an insect neurotoxin
and belongs to a class of chemicals called the neonicotinoids which act on
the central nervous system of insects with much lower toxicity to mammals.
The chemical works by interfering with the transmission of stimuli in the
insect nervous system. Specifically, it causes a blockage in the
nicotinergic neuronal pathway. This blockage leads to the accumulation of
acetylcholine, an important neurotransmitter, resulting in the insect's
paralysis, and eventually death. It is effective on contact and via stomach
action. Because imidacloprid binds much more strongly to insect neuron
receptors than to mammal neuron receptors, this insecticide is selectively
more toxic to insects than mammals.
