Does epsom salt kill ants

Yes, epsom salt can work on ants but not particularly get rid of them if the infestation is large. Mostly ants came for sugar type, even tea, bread with jam etc. The solution that works is using white vinegar and not epsom salt and if you really think they came because of sugar then wipe the area with detergent or mopping liquid. 

Ants make their way easily when they see sugar or any kind of food how they smell it it still a big theory but get rid of them is using epsom salt is not a effective way and if you don’t have anything just spray water I did it and and if your their line they will just disassemble or sometimes I use sanitizer and even add normal edible salt to make it effective for many pests. This is my personal trick, it works for me. Btw Here Sanitizer is Cheap So Lucky me.

Why does salt kill slugs

Salt kills slugs easily as this insect has water in its body and salt just reduces the amount of water from its body and the moist body of the slug can’t stay longer without water that results in instant kill and the reason behind it is dehydration. It’s very heartless, inhuman and vicious but sometimes you just have to do it for your plant so they can live longer and always stay healthy and produce diseased free foliage.

If the epsom salt didn’t work for cutworm then use coffee grounds and put it around the soil. And the good part of coffee is that it contains essential nutrients that a plant needs to grow. It also works as fertilizer and also it could be helpful in providing sufficient NPK(nitrogen, phosphorus and potassium) to the soil that helps plant in its overall growth.

Another method can be applied to keep the earthworm and slug entering the soil using eggshells or that white/brown cover on the eggs. You just need to crush the eggshells and that’s it. Now if any earth worm or slug comes by they will have to face the sharp edges of shells and it will cut the tiny legs of any angleworm so it is helpful in protecting various plants from snails, slugs and earthworms.
