Giant African Snail (Achatina fulica)

Am I in trouble to have these snails in the house compound in Miri? I saw them on the ground hiding in the previous cut grass pile.
Actually, these snails are quite commonly found in Sarawak.
They are invasive species mainly fed on the leaves and perhaps the grass. These wild snails often have parasitic nematode which causes meningitis to humans even by just handling. So watch out!! 
In some countries, these snails are cooked as special dishes,oh gosh, look disgusting.
