Many wild creatures living in the urban interface are impacted by eating poisoned rodents. That includes coyotes, bobcats, gray foxes, great horned owls, barn owls, red-tailed hawks, red-shouldered hawks, and raccoons, just to name a few.

I looked at some d-con for mice off the shelf at Rite-Aid.  Near the bottom of the label under Environmental Hazards: “Predatory and scavenging mammals and birds might be poisoned if they feed upon animals that have eaten the bait.”

But who reads labels these days.

The Victor Fast-Kill rodent poison just says “it may take 2 or more days from the time of bait consumption for these rodents to die.” They say you can use the stuff indoors or outdoors! The box says nothing about secondary poisoning.

Native Bird Connections already has educational information on their website regarding “one feeding kills” rat and mouse poison that’s available in stores everywhere. You can read more about this at

So we just need to direct people’s attention to the subject.

Thanks for the information, especially the link to the Native Bird Connections website (read down to the bottom of the page to get to details on the secondary effects of rodent poison).

People need to read about this and be aware that it IS NOT A GOOD THING to use these nasty poisons for any reason!

Another thing: Rats and mice will sometimes pick up pieces of poison bait and carry them away and leave them in another area. The “other area” may be a spot where the poison can be found by pets and/or children.

Bottom line here: Don’t use poisons. /Gary

  1. Salesman Says:

    With the sparse and brief freedom our EPA has recently had (and lost?) it appears they managed some relief from these horrific poisons. Effective July, manufacturers can no longer produce/sell small doses. There will be an 8# minimum, with the assumption (I guess) that bigger agricultural users are more educated on how to use these mini-horror shows of rodent baits. Fat chance, since there is not a safe way to put them in our environment at all!

    If I had a dollar for every time I have seen or heard of another idiot who didn’t know how to read the warnings on the label (or ignored it), I could retire.

    My favorites are the idiots who throw the dead (toxic) rodents in their ponds. WTH!

    Yet another reason to BEG your legislators to FREE the EPA – and let them do their job!
