Are you facing a situation whereby small snails would not allow your water leaf, pepper and tomato seedlings etc to grow. What can you do?
If it's a house garden. Pick them and start snails farming, they will get bigger, feed them with water melon. Pick them up turn them out or fry and eat. It is called "sweet small bush meat suya".
Start picking and training the snails. It could even become better than those crops. As for me, I pick the snails and i don't throw them away. Yes, they can become a challenge, because they eat up all pepper flower, vegetables sprouting out, including melon flower. But, you don't have to poison them by adding salt in water and sprinkle. It will kill the snails and keep them away. Not salt but omo. Omo specifically or any detergent. I have tried this a long time ago and it worked for me. Or better still, blend garlic, pepper and lemon grass. Sieve, add water and spray the solution on the leaves as well as boundaries. Also, you can buy Mocid, it's a molluscicide that kills those small snails. To apply this one, the way to apply is written on the product, just buy it and read the instructions on the product.
Why don't you save guard the snails for personal consumption is even richer than pepper and tomatoes. Start up snail farming..it's lucrative. You are simply unable to appreciate what protein God is giving you to cook your vegetables. Yes, I know it is the same vegetables you are suppose to use them to cook, it's what they are eating, lol.
If you have been eating them, none will be sizeable enough to eat your vegetables. I have them in my backyard garden that is constantly flourished by borehole water and banana plants. My neighbor harvests and cages them daily for her next pot of soup. How else do you want God to answer your prayers ? What is pursing a man determines his speed.
Yes, I know some people really like them as a source of protein but don't really fancy the small ones. If it is a mass invasion, do Ash spray. Mix Ash and water and spray on your garden. At least once in a week
