Natural insecticides suggested for specific pests

March 2, 2008
  • Pour boiling water or pure lemon juice directly onto the nest.
  • Check for aphids, because they produce a sort of honeydew that attracts ants.
Cabbage maggot
Cabbage worms
Carrot rust fly
  • Clay.
  • Insecticidal soap.
  • Petunia or marigold tea.
  • (Rhubarb): VPour boiling water over a few rhubarb leaves. Let steep for 24 hours. Strain and combine a few drops of this mixture with 1 tsp (5 ml) of lemon-scented liquid dish soap, 1 tsp of Listerine and 1 tsp of ammonia (lemon-scented is best). Add 5 ml of this concentrate to 1 litre of water and spray on plants twice a week.
Leaf beetles
(striped or spotted)
  • Spray onto and pour around the base of pumpkin, zucchini and cucumber plants.
  • Stir a handful of lime or wood ash into 8 litres of water.
Leaf miners
Lily leaf
  • Blend 2 Tbsp of rubbing alcohol with 1 litre of insecticidal soap solution.
  • Spray onto plants every 3 to 5 days until the insects have disappeared.
Plant bugs
Potato beetles
Scale insects
Scale mites
  • Garlic potion.
  • Partially bury containers full of beer around your garden: the slugs will be attracted to the smell of the beer and will drown in it.
  • Place crushed egg shells around the base of affected plants.
  • Spread dolomitic lime around your vegetable garden or wood ash between rows.
Spider mites

    This is a really excellent section to have in here, as would be any other sections on alternative/innovative practical uses for given species. I think the category name in the category menu should specify that these insecticides are natural, even though insecticide does not actually imply that it is artificial.
