German cockroaches

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)

In the event that you cannot obtain an IGR labeled for homeowner use, you might try this bait formulation which is supposed to remain effective for up to a year – Click here or this one – Click here
