Mix a tablespoon of Cocoa Powder with plaster of Paris and sprinkle it around the standard areas that mice tend to frequent. The cocoa powder attracts the mice to eat up this mixture. Eventually, it leaves them feeling dehydrated and suffocated before they rush out to die.
One way to do this is to mix some cocoa powder and flour with baking soda or boric acid. Baking soda or boric acid creates a lot of gas inside the rodent's digestive system. The mouse does not have the ability to expel this much amount of gas, so it eventually kills them.
Snap traps are the most effective way to do that. Another way is to mix boric acid with peanut butter into small circular balls and leave them around the home. The boric acid affects their nervous system and will kill them in a few hours.
Zinc phosphide is an acute toxicant that causes the death of a house mouse within several hours after a lethal dose is ingested. It appears to be the fastest way of getting rid of mice by reducing their population.
Mice or rats die in 24 to 36 hours when exposed to baking soda due to its strong alkalinity, which is well beyond the levels they can handle. Baking soda is natural and mice or rats cannot discriminate between it and food. It does not have to mix with poison or other substances for mice or rats to ingest it.
To make this flour, sugar and chocolate rodent bait: Pour equal parts sugar (either white sugar of castor sugar), flour, and baking soda into a small container. Add a little chocolate powder or chocolate sprinkles for extra flavour, and mix it well. The chocolate is optional, but it makes the bait far more enticing!
The pungent smell of vinegar is also a natural way to repel mice and rats. These pests cannot stand the sharp scent of vinegar, which means it can be used as an effective rodent repellent. You can use white vinegar or apple cider vinegar for this purpose.
The LD50 (100 days) ± S.E. (oral dose of paracetamol which killed 50% of young male albino rats when given daily for 100 days) was found to be 0.77 ± 0.02 g/kg per day. The maximal LD0 (100 days) was estimated to be 0.4 g/kg per day, and the minimal LD100 (100 days) 1.1 g/kg per day.
Yes, you could technically kill mice with toothpaste, but it would be very difficult to get them to eat enough that it would be fatal. Apparently, mice that eat toothpaste that contains fluorine and ethylene glycol would die from those ingredients if they consumed enough of them.
Grapes/raisins, chocolate, avocado, garlic, onion, rhubarb, coffee, tea, alcohol, and walnuts must not be fed as they are toxic to mice. Lettuce should be avoided as it can cause diarrhoea in mice [4].
Bromadiolone is a rodenticide meant to kill rats and mice. Anticoagulants like bromadiolone work by preventing the blood from clotting. Unlike some other rat poisons, which require multiple days of feeding by an animal, bromadiolone can be lethal from one day's feeding.
Yes, you can kill mice with salt, but it's a fairly difficult process. Like their rat brethren, mice will die if they consume too much salt and lack access to water.
Citronella. Citronella is good for more than repelling mosquitos. It is also a successful way to eliminate mice, as the strong smell is often too much for them.
Classic snap traps are commonly used to kill mice within homes. For best results, these traps should be set flush to walls, with the trigger plates facing the wall. Glue boards may be effective, as well. If placed properly, the mice should become caught in the glue and unable to free themselves.
At 500 mg/kg, paracetamol produced 30% lethality in 3-wk-old mice and between 50 and 90% lethal- ity in the adult age groups. There was histologic evidence of hepatocytic necrosis at all of these ages and its extent increased with age.
Of 14 mice treated with ibuprofen, 10 (72.5%) died within 10 days, and in contrast, all 12 mice in the control group survived (p < 0.001).
Ibuprofen was shown to inhibit lipopolysaccharide-induced cognitive dysfunction and neuroinflammation in rats [19].
Repel rodents and insects
Rats, mice and other insect don't like the smell of peppermint, lemon, and cinnamon. Make tea with these rodent irritants and place the used teabags in places like the back of your pantry, under the kitchen sink or behind the refrigerator to repel these unwanted pests.
There are two main things that can attract mice and rats to your house – food and shelter. If you don't tidy up properly and there's food waste on the floor or surfaces, rodents are going to love it! Rats and mice also need shelter, particularly during winter to avoid the worst of the cold.
Sprinkle scents they don't like
Mice don't like the smell of garlic, onions, cayenne pepper, cloves, ammonia and alcohol. If you don't want to be driven out your home by unpleasant smells either, peppermint is another scent that repels mice.
Disposal of dead rodents should involve spraying the rodent with a disinfectant or a mixture of bleach and water (1 part bleach to 9 parts water) and putting the dead rodent in a tightly sealed plastic bag. Place that bag in a second plastic bag and seal.
Instead of catching mice, like mouse traps do, ultrasonic devices emit sound waves at a frequency that mice find absolutely unbearable. Ultrasonic devices with a sound frequency of 10,000 Hz are most effective at keeping mice away.
Bleach is not the best solution to repel mice
So, the unbearable pungent smell can repel them, keeping them off properties where they are sprayed. Bleach can also kill mice if consumed in large quantities. You can also use bleach to kill harmful bacteria on mice droppings.
