Using Natural Products to Control Garden Pests
Destroying pests with chemicals upsets the balance of nature and can
harm the soil. Listed below are some of the traditional ways of destroying
or controlling pests using natural materials. Please note that we can
not be held responsible if any of these do not work in your garden.

with the liquid.

Cabbage Root Fly
- If there is enough humus in the soil the cabbage roots should be
sturdy enough to shrug off the effects of the Cabbage root fly.
- After hoeing the ground, sprinkle the ground with dried wormwood,
hyssop, mugwort or southernwood, the fly will be attracted to these
instead of the carrots.
- Sow Parsley or any member of the onion family among the carrots to
disguise the smell of the carrots.
- Sow onions from sets instead of seed.
- If growing onions from seed plant parsley nearby.
- Grow fragrant herbs such as hyssop, sage, thyme, mint or rosemary
near the cabbages.
- Compost grown plants can normally withstand caterpillar damage with
no long lasting effects.
- Spray cabbages - not cauliflower or broccoli - with sea water.
- Repel them by growing tansy or pennyroyal
- If ants are invading your house, find out where they are getting
in and lay bay leaves along their track

baby powder on entry points.
