The Karbidbrocken of this product are of different sizes, most of them but about 2 cm, which makes sense. So I have times put two pieces in each of the still wet after a rain mouse holes and passages, reingeschoben deep with a stick and everything immediately sealed with wet earth, and the side gears. Some holes were so wet that the carbide hissed immediately because it decomposes with wetness.
And it does this in a heap of highly hazardous substances!
Chemically, carbide decomposes into acetylene and an amount of inorganic and organic phosphine compounds, the smell of garlic and are highly toxic: For mice and humans!
This disadvantage is also an advantage, because if you do the mouse holes tightly with earth, it says, from the mouse!
Basically carbide is a kind of "slow motion smoke bomb", a gasification with time fuses: Stuffs to the carbide shortly before rain lush in all holes, then sets at a rain a real Holocaust in the ground. That's awesome, that's brutal, but as property owners, threatening the landslide and depreciation, you have to be little scope for Plage Men for, also with regard to the neighbors who complain quickly if we do not sustainably get the problem under control ,
Carbide and phosphide, ie substances which develop gas in the ground, by the way are also often used by foresters and exterminators, ie from the "professionals" when epidemics are true!
In short: The product is here!
Just take good care during application of the product: wear gloves, work only in calm, shallow breaths or attract Gasmske, because you have to be clear: carbide smells slightly of garlic because of Phosphanentwicklung by humidity. In the moment when you smell it, you can already easily poisoned! So be careful, work carefully, leave lying around no crumbs anywhere!
Overall, however, the product is excellent, better than zinc phosphide for the layman!
Oh yes: Since my "declaration of war" on the mice invasion a week ago, actually came to no new hill.
Creepy ...
