Why is insect control necessary?

Although most insects do not cause us problems and many are benign or even beneficial even in our homes there are other insects that can cause problems. These may need controlling for reasons such as preventing the spread of disease, preventing damage to livestock and crops or property, preserving public health or public or safety. Some insects can bite or sting (such as Fleas, Bed Bugs or wasps) while others spread disease such as cockroaches which can spread diseases such as Staphylococcus spp., E Coli, Shigella spp., Salmonella spp. Other insects are significant because of their role in damaging or contaminating foodstuffs, such as Grain Weevil, Flour Beetle, Grain and Flour Moths etc.
