Mouse poison not working so good?

Butch(OH) · Dec 9, 2020

For many years we have used the green blocks of mouse and rat poison, Tomcat brand with good results, now it seems the rats and mice are getting fat on it? Don't know if they are building immunity or the formula has changed? Anybody else ran into this and what are you all using? My shop is heated 24/7 and I am about to be over run with mice!

I've found the pellets work the best guess it takes less effort to eat them.Need to get rat poison at a farm store heard its a different better poison than homeowner poison.They do ask at the coop if its for farm use.

some of it needs water for them to drink to work well,, got the wife feeding cats in all the building have not seen a mouse, well a live one in 10 years now, I guess, do have the cat spray and poop to deal with but I much prefer it to rodent joys

The last couple years I have been using some mouse glue traps. They seem to work well. This trap was put out about a week before this picture was taken.

For the bucket, drill two holes opposite near the top. Put a metal rod through. Make a roller out of PVC pipe with end caps. Drill the holes a shade larger than the rod so it will roll easily. Put a dollop of peanut butter on the rod. The mice will be attracted, and when they try to get a snack will fall in the water and drown. I put rv antifreeze in the water. I got 22 mice over night at a rental house that was infested, and close to fifty in a week.

I’ve used a coat hanger with a small pop bottles smeared in peanut butter. It’s like a mouse resort with a deep swimming pool.

I use the bait bars in the unheated areas and glue traps in the heated areas. I found the mice would carry the pellets back to their nest and not eat them. They chew on the bait bars and head for an open area to die. Just have be consistent about having bait and traps always out for them. Eventually the population declines.

"Havoc" will get the job done.

OregonAaron · Dec 9, 2020

The tomcat poison doesn't seem to work too well. I have been using "Ranick" poison with good luck.

Super H Mike · Dec 9, 2020

This works well for me also. I put used antifreeze in the bucket. Bonus is they don't stink while decomposing with the antifreeze instead of plain water.

If you dont have cats Tomcat use to sell a liquid you mixed with water and put in a chicken waterer, had a customer when I worked a local feed store said it was the beast.

Mike M · Dec 9, 2020

I always seem to find the green pellets stashed in all sorts of things as the don't seem to eat them.

Jim in rush co · Dec 9, 2020

Local co-op got me to using Havoc years ago, kind of high in price but works. I use the packets and comes in a 3 gallon pail.

MF243RedTop · Dec 9, 2020

Left a couple packs of the green blocks in the "open storage compartment" on my golf cart parked in my building. The mice got into them chewed holes into them and committed suicide 😂
Never had to place them out....
True story..
Now have an outside cat.. no mice to speak of.

I've got a big old black snake that stays in my shop. I never see it just see the skin when it sheds, over 6' long. If I see it, it's dead, but I have no mice or birds in there anymore.

I have Tomcat brand cubes in cabin at the hunting lease. They seem to lose their potency after a year or so. My cubes are about 3 years old. Right now mice seem to eat it like candy...

DoubleO7 · Dec 9, 2020

We use the tomcat green blocks too.
But we shave the blocks into pieces about same as what a rat nibble should be.
Mix it in with peanut butter.
Smear a glob on building wallss, etc. down low here and there in the outbuildings.
But not where domestic animals can get to it.

But during the summer we had a six foot and four foot yellow rat snakes move into the chicken coop. They might be hiding out under the floor, maybe gone now.
But have not seen any rodents in the past three months.

JL Ray · Dec 9, 2020

I have used the water in a pail thing with some success. I buy Tomcat in the M+M bags. I just throw them in the corners of the building and don't open them. You know if you still have mice around if they get opened up, so I throwing more down. By not opening them the product stays fresh a bit longer too.

DoubleO7 · Dec 9, 2020

If you have easier and more tasty pickens piled up all over, most any poison is not going to be effective.

(quoted from post at 15:21:57 12/09/20) This works well for me also. I put used antifreeze in the bucket. Bonus is they don't stink while decomposing with the antifreeze instead of plain water.

This one is in the basement so I don't use anti-freeze in it but I do in the ones in the outbuildings. I check this one every day and occasionally catch a mouse......' had one today but I had already dumped him so there's none in the picture. I've used 2 liter soda bottles mostly. I used a Clorox wipes container on this one....we've got lots of them lately. Used wine bottle corks to center it........seems we have lots of them as well nowadays. LOL

They build up an immunity to the poison. You need to keep changing up the type of poison.

When I left my farm, I was using "Just One Bite" poison.

Poke Here

I buy it in the packets also. Local Orscheln's has it in 5 gallon buckets. Pricey, but it works.

Copperhead don't play · Dec 9, 2020

[ Mike i have the same problem. The mice just carry the poison and store it somewhere else.

Copperhead don't play · Dec 9, 2020

AS bad as I hate mice, I think I would prefer them over a snake.

farmerjohn · Dec 9, 2020

Ironic that you say that as your handle is the name of a snake.

John in Mich · Dec 9, 2020

I have kept D-Con in the garage for 35 years (freshen up every couple years). I keep the doors closed except for the short time of getting wife's car or my truck in and out.
I have seen a couple mice, over the years, run into the garage. One I found in a pail of soapy water that I had used to wash my wife's car the a day before. We have never had a mouse in the house...so far.
On a side note, I have a live mouse trap. It is a metal box with a oneway door. It has had a mouse sleleton in it for years and I have tried to sell it at flea markets, mouse included. I had put it out of my trailer by the front of the barn to throw away. One day I picked it up and, be danged, there was a second dead mouse in it. I never even put any bate in it. I'm leaving it outside to see if any more mice want to join the club. LOL

Mix up 1/3 each flour, baking soda and sugar, place around building.

Olliejunkie · Dec 12, 2020

I had a family of rats by my barn. I put a couple traps out and caught quite a few. One of the traps disappeared so I will have to tether them down. Anyway it seemed like the rest of them decided it wasnt a good home and moved on. They're back now as my mother insist on feeding birds and throws crap out to the chickens that they dint eat. Time to put out more bait.

4play · Dec 12, 2020

Im pretty sure tomcat brand uses bromethalin as the active ingredient. This is a single feeding, or single dose type poison and not an anti-coagulant. I'm not sure if rodents can build immunity on single dose killing poisons, but I'm not an expert. It's never a bad idea to change products though, not just changing brands but making sure you are using something with different active ingredients.

One thing about putting bait/poison out. You should try to eliminate all other food sources if possible. If rodents have plenty of other food sources, they might not target the bait, or consume a lethal dose. I also tie a string to the blocks or nail the blocks to a board, that way they are forced to eat and not carry it off. One bait block can kill several mice, or a couple rats but if one carries it off, it might only kill that one.
