Letter to "Friends of the Fells"

The Flynn Hockey Rink 'bait stations'

The Flynn Hockey Rink is using Poison Bait Boxes along their building. They number about 8 in all.
I contacted the DCR about the native rodents like field mice, squirrels and chipmunks which fall prey to these items, as well as the 'secondary poisoning' of predators like hawks, owls, foxes etc which happens. This is the response I received:

Good morning Francis,
Thank you for reaching out to the DCR with this concern, and I apologize for the delay in response. This is the email for the Community Relations department, so this is the correct place to submit any questions, comments or concerns.
I spoke with our Regional Supervisor around Flynn Rink, who confirmed that the managers of the rink are responsible for these bait boxes. The brand being used is RatX, if that’s helpful. Let me know if you have any other questions or concerns and I would be happy to pass them along.
Best,
Thomas Tinlin (He/Him)

If it were RatX, at least secondary poisoning wouldn't occur. It's designed not to do that and is one of the reasons it's used where secondary poisoning can occur. But I was skeptical so I bought the key to open the boxes.
It wasn't RatX inside. It was a bluish/green poison: I've both provided an attached video and the information below:

These blue baits typically contain anticoagulants (like brodifacoum, bromadiolone, or difethialone), or acute poisons (like bromethalin). Because they are designed to kill, they are extremely hazardous to non-target wildlife and pets

Unlike traditional chemical rat poisons that are dyed bright blue or green, RatX pellets are tan to grey. RatX is an all-natural, non-toxic rodent control product made primarily from corn gluten meal and sodium chloride (salt), designed to cause fatal dehydration.Traditional rodenticides are dyed green or blue specifically as a safety warning to humans and to help veterinarians easily identify the cause of poisoning. Because RatX is non-toxic and humane, it does not require this coloring.

I still hate that native rodents are being poisoned by these thing, and the first time I noticed them was when I saw a chipmunk go into one, but at least they don't cause secondary poisoning and I could relax a bit. When I decided to buy the key to unlock the bait boxes, just to make sure the information I received was correct, I was both surprised and horrified.
So how did this misinformation from Flynn's manager, to the Regional Supervisor, to Thomas Tinlin and then to me happen.
Maybe the exterminator made a mistake, maybe someone willingly lied, I can't say.
Whatever the rink does inside their building is one thing, but those Poison Bait Boxes are within a few dozen feet of the Middlesex Fells. If you agree that they have no place there please alert the DCR to address this problem.
If you can get back to me on any progress made-and I suspect it won't be easy-please do so.
