There are a large number of Invertebrates, or Insects as they're better known, that are widely regarded as pests.
Wasps, Blue and Green Bottle Flies, Common House Fly, Lesser House Fly, Cluster Flies, Drain and Fruit Flies, Garden Ants, Ghost Ants, Fleas, Silver Fish, Carpet Beetles, Wood Lice, Cockroaches, Stored Product Insects and Case Bearing Cloth Moths; far too many to mention.
Summer marks the start of the wasps, flies and ants season; Autumn arrives and so do the cluster flies in our lofts and windows. With each season a new type of insect comes to menace us for the duration.
