Grubs are a problem in the garden because they feed voraciously on the roots of grass, flowers and vegetables. Grubs are the larval form of many insects, and you'll find them when you turn over the soil. They can damage plants and kill those that are stressed by disease. When you notice grubs in your garden, they need to be driven away as soon as possible, and a simple aluminum pie tin can help.
Cut up between three and five thin slices of cucumber, using a sharp knife.
Lay the cucumber slices flat in an aluminum pie tin.
Set the pie tin in an area of the garden where you are having problems with grubs. The reaction between the pie tin and the cucumber creates a smell undetectable to humans that drives away grubs and some other insects.
