heavily infested by roaches---killed them all by one spray
We have one apartment heavily infested by German roaches. We did some research and found out the chemicals used by professional pest control company. Sprayed the two pestcides mention below once and killed them all. For safety, you can spray the 2nd time within 1-2 weeks.
The following 2 pestcides which are used by professional pest control company: Alpine WSG, Gentrol Point Sources IGR (which is one kind of growth regulator).
如题， 原来的老房子很多小蟑螂，去年搬家以后厨房的东西还是搬进了新房子。 结果今年已经看见了三只小蟑螂。 怎么处理？ 新房子比较大，感觉用蟑螂炸弹不管用啊。
蟑螂最难处理，会不断孵化出来。
