How can I stop earwigs eating my Dahlia flowers?

Our Advice:

Fill a clay pot with straw or dried grass and add a small amount of PY Insecticide Powder from Vitax or Wasp Nest Killer Powder from Doff. Place it (upturned) on a cane positioned at the same level as the flowers. After the insects have been feeding (usually at night) they will hide in the straw and are affected by the chemical.
