...nothing beats DDT for killing those rascals.

But it also kills off bees and other useful insects. Precise application is critical.

[woodbutcher1963]

Diazinon(now illegal in crystal form) also was great for killing insects and apparently you and me eventually. It is supposed to be a cancer causer.

I use that to kill carpenter ants. I used it one time to kill all insects when I had a bad case of beetle grubs about ten years back Diazinon will kill an ant hill in about ten minutes.
