Is it possible to smoke rats out of your attic?
Helen Marshall says
We been trying everything blocking holes , steel wool, traps, coke, mothballs.we cant seem to catch them.
Ok this might be a little over the top, but I know it works great.
Norway rat’s are smart, but they go into their tunnels during the day.
What you need . A gallon of Muriatic acid, a bag of Galvanized nuts
And bolts . A average size glass jar. Put the galvanized nuts and bolts
In the jar. Find the hole they go into, carefully dig next to the hole just
To one side about 2 “ inches deeper than the hight of the jar,. Place the jar into the hole. Find something to cover the entire hole, be careful not to let dirt block the rat hole, have something heavy to place on top of the you’re cover. This is the good part, pour the Muriatic acid into the jar, fill it up, cover the hole, and place the weight on top.
Don’t get to close to the fumes it’s really really bad stuff, the reaction
Of galvanized metal and acid will sink into the hole and asphyxiate the living. Most of the time it’s 100% . However sometimes they get out using the escape holes. Find them by observing the smoke coming out and cover them up good, repeat the process. They won’t be back.
Be sure to use caution ! Don’t breath in the mixture, it is toxic….
Thank you so much for this.
