Do you know how or where I can purchase insect growth regulator in Canada. My son has purchased a house that ended up having German roaches. We have contacted a local exterminator who for $1000.00 will take care of the problem but only guaranteed for 45 days. Sounds like they will kill everything alive but the next generation. Regina.
I have found these IGRs recommended for German cockroaches:
Gentrol Point Source (Zoecon) – (this can be shipped to Canada)
Vendetta Plus Cockroach Gel Bait (4tubes) Roach Bait & I GR Roach Killer Paste – (I do not know if this can be shipped to Canada)
