LiphaTech, the producers of Generation and FirstStrike, is petitioning to have DFN products re-instated for outdoor use.
What the Industry…let me re-phrase that…what you need to do is simple:
Read the attached letter from LiphaTech on the issues.
And if you agree, contact the persons outlined in their letter and add your voice of support.
This is an important task, simple to do, but one with major consequences for all of us in Pest Management.
So take the few minutes and write, it will certainly help the cause!
The Industry needs your help as Professional Pest Managers.
You are all aware of the PMRA’s actions on the rodenticide re-evaluation decision, and the effects on domestic and commercial baits. But there is one part of the decision we as an Industry should try to have reversed, and that is the limiting use of difethialone (DFN) baits for indoor use only, completing eliminating the opportunity to use outdoors. The names more familiar to you would be Generation and FirstStrike.
The PMRA has lumped this bait into the same category as brodificoum, based on arbitrary levels set in one or two chemical properties.
What was ignored was the fact the bait is used at 50%, or half the rate, of brodificoum, and the properties of the products are much closer to bromodialone than brodificoum. But this and other factors must have taken into account by the EPA, as PMP’s are still allowed to use DFN products both indoors and out in the States.
So what else does the current decision mean and what impact can it have?
There is now only one second generation anticoagulant available for outdoors. And what, after 5 – 10 years of using one bait for outdoors, will we build up a resistant population of rodents???? Possible??? Who knows, but why take the risk. And do we want to chance ruining another great active by overuse, leaving Canada with no effective bait for outdoors, where you need to stop infestations from coming inside?
The second issue is bait shyness, which we all know develops after continual use and feeding. This will also impact choices…leaving us with products that aren’t any where near as effective.
So what do you need to do to help?

No I’m not talking Holidays! Basically it’s that time of year when the degree days are adding up and insects are on the move.
Biggest issue I am encountering now is carpenter ants, with high activity levels indoors, more so than outdoors. No swarmers as of yet, or in very limited pockets, but should be expected in the next few weeks.
Hopefully we will be seeing some new active ingredients pass through the PMRA as we are in dire need for new ant baits to fit everyone’s IPM programs. Plus if we continue to rely on the same actives year in and year out, although we may not have a “true” resistance problem, overall effectiveness will start to diminish. I firmly believe we have developed resistance to some pyrethroids used on cockroaches.
There are at least 3 new actives waiting in the wings, with the capability for dusts, baits and dilutable formulations. Look for more posts on these in the coming weeks as I am trying to check on the status of each.
Next up…more on the Rodenticide re-evaluation decision and some major concerns and actions from Industry that is going to take place.
Plus an overview on resistance management, or lack thereof, in the Canadian market.
