By experimenting with combinations of chemical,
manufactures have produced a wide variety of affective
dusts and sprays to control plant pets. Some, such as
those containing pyrethrum, work well and do not
harm the people, pets, and birds. There are others that
contain stronger chemical, such as DDT, melathion,
diazinon, and chlorine. These can be extremely
dangerous if they are not properly used.

The first thing to do in dealing with plant pets is

stores can supply valuable information on the correct
product to use. If the problem is a complicated or
