Rat Poison vs. Cockroaches


I have put some rat (mouse) poison in one of my cabinets because of a serious amount of mouse droppings. Lately I have found roaches (the big ones) feasting on the rat poison. My question is, is the rat poison going to kill the roaches?
My plan is to buy some roach poison, but if the rat poison will eventually kill them, I'll just let them keep eating that!
Thanks in advance,
Sue

I put out some mouse traps with peanut butter on the trigger and ants came along and ate the peanut butter. I put out ant bait and mice chewed the carriers open and ate the ant bait. It's a pest conspiracy, they have meetings you know.

If it is Warfarin, it is a substance that interferes with blood clotting, so the animal dies from bleeding, essentially. I don't think the cockroach has a blood clotting system that would be susceptible.

Rat poison may kill roaches but I would also buy poison designed for roaches. Toxicity towards various substances can vary greatly between species and you want a poison designed for the target pest.
I prefer to trap mice in the old fashioned snap traps. I've used poison but dead mice in the walls may cause a stink.

It is likely that the rat will die (usually 3 to 5 days after ingesting the poison) in a wall and stink up your house for an extended period of time. I recommend using poisons outside and traps inside.
Happy hunting!

Sprinkle Boric acid (Roach Prufe) powder on the surface and put the rat poison in the middle.
The Boric acid won't deter the rats, but will wipe out the roaches. It isn't poisonous, but interferes with there reproductive system.
Boric Acid doesn't do much against ants. However, if you lay about a 1 inch circle of Seven Dust on the outside perimeter of the Borid acid spread, it will kill the ants. You may also have some dead roaches to clean up, tho, so if you don't have an ant problem, don't use it.....
Boric acid isn't poisonous to people, and has been uses as an eyewash when chemically pure. It is also called orthoboric acid. It' won't kill pets but will completely eliminate a roach problem...
Personally, for mice/rats, I use standard traps baited with peanut butter. If roaches are a problem, I put it in the middle of a Boric acid spread......
..... ya gotta tailor the weapon to the pest...

Wiki says it has a toxic effect on roaches if eaten by them, and it also mucks up their exoskeletons.
My experience is that Combat and similar roach baits are somewhat effective.
Also in my experience, little else easily available kills roaches except brute force, heat, and getting them wet with organic solvents.

Here's a DIY recipe for a guaranteed killer roach bait.
1/4c boric acid 1/4c flour & corn meal mix 2 tbs bacon grease 1 tsp sugar 1 tsp minced onion. Add just enough water to make a semi-stiff paste. Roll in small balls and place under appliances, in cabinets, closets, etc. (anywhere pets can't get them).

No doubt that will kill the roaches.....
In a couple decades of renting houses to people who often weren't as clean as I would have liked, I used the following method to get rid of roaches:
I open all the cabinets and nooks and crannies in closets and put in a tablespoon of Boric Acid. Then I would set my vacuum cleaner on "blow" and blow the powder around in such a manner as to put a very light coating in all the dark places, under counters behind drawers, etc. Then I would warn the tenants not to vacuum up the powder if they came upon it.
Within a few days there would be no roaches, and there would be no dead roaches all over the floor or in the cabinets to clean up...
Whatever the mechanism, the critters apparently went back to their nests to die.
I didn't use poisons, since that would leave dead roach bodies all over the place, be harmful to pets and small children, etc.........
Just the powder did the trick....
Another way is to dissolve the powder in water and use a sprayer to coat everything I could find. The water would evaporate and leave an ultra thin residue on the surface that also worked well...... They don't have to eat it, just walk on it.....
Anyway, I'm just passing along first hand experience that was developed by trial and error. If you have a better way, this is certainly the place to post it...

Seems like a lot of trouble, no offense. I got rid of mine by simply strewing boric acid in all likely places INCLUDING under shelf paper and drawer liners. Around baseboards and entrances, of course.

When I just dusted it, it left a powder that tenants in the house tended to vacuum up in their efforts to "clean" the place.
When I used the vacuum cleaner on "blow" , it tended to coat every damn thing in the place, cling to walls and filter into crevices, and didn't leave little piles to attract attention.....
Same thing with dissolving in water and spraying....
As far as Red's idea of mixing it with stuff that roaches like so they will eat it, .... I'm sure that works , also. And the smell would attract roaches from other planets to come and feed also. Maybe that's a good idea. I'm sure it would attract my dogs, who would lick the stuff up and clean it for me. Probly wouldn't hurt them, but they don't seem to have any interest in plain old Boric acid..... I've tasted it and can't blame them.....
Actually, maybe I could smear some on their private parts so they wouldn't lick themselves so much when guests come by...... just thinking out loud..

My bet is rat poison will not hurt a roach. Rat poisons are usually anticoagulants and I imagine an insect's system is different enough that it won't hurt them.
You may be sorry you used the poison anyway. If that mouse dies in the wall you will be living with the smell for a while.

Ayup. I've had that exact thing happen. The stench lingers until the carcass mummifies, which can take months. And you'll /never/ locate the body until you start ripping out walls!
As far as I know, cockroaches have a series of air tubes in their bodies. It is these which carry oxygen to where it's needed. Warfarin only works on animals that have blood-circulatory systems similar to humans, so it won't work on roaches.

I live in the country and it isn't uncommon for a mouse to take up residence in the engine compartment of a vehicle. Eventually they may work their way into the air conditioning system and, when the fan is run, become dead. Then they start to stink. Then the car starts to stink......
I have had that happen several times , with various vehicles. The only solution was to remove the fan and clear out the carcass.
This is much stronger, and much more POTENT than a dead mouse in a wall.... When you run the heater in the winter time, you have to roll down the windows.....

PS The solution, for those who live in the country, is to find a place in the engine compartment to fasten some mouse poison bait. There is a product I use that has rectangular green blocks with a hole thru the center. I stick a piece of wire thru the hole, and fasten it to some bare spot in the engine compartment. I check it every couple of weeks to see if it has been eaten on, and replace it as necessary. I often find dead mice in the middle of my driveway now..... :>)))))

Would you mind cleaning my house, too?
