Natural Pest Control – Aphids

These sap sucking pests are around all summer long in small amounts but their populations increase impressively in late summer. Some of the first signs of an aphid attack are shiny sticky leaves with white or black flecks (egg casings), yellowing or misshapen leaves, and a general overall lack of thriving growth. Here are some strategies to help cope with them.

Who they are:

  • tiny bugs that hang out on undersides of leaves or on stems
  • can be almost any color of the rainbow ranging from green, pink,  yellow, to grey or – black
  • they are the size of the colored head of a sewing pin, so easily seen with the naked eye

What They do:

They suck the nutrients out of plant leaves.

Aphids Love:

  • Dianthus
  • Petunias and Calibrachoa (Million Bells) especially purple and yellow varieties
  • Lupines
  • Nasturtiums
  • Dahlias
  • Manitoba maples

General Strategies to decrease bug infestations:

  • have ‘trap crops’ away from your garden.  Trap crops attract aphids & they will stay there & feed.
  • ‘Trap plants’ include: Manitoba maple trees, lupines, mint, fennel, dill, dandelions, yarrow
  • plant garlic & onions – aphids hate the smell
  • spray with a strong flow of water daily until they are gone
