Pest repellent plants


Several plants are known to repel moles. Daffodils, frittalary, scilla flowers, castor bean, garlics, and caper spurge.

To deter mice: peppermint, perennial sweet peas, muscaris, and again daffodils and scillas. Also wormwood and garlics.

To deter cats, besides laying barriers with thorny sticks, rue is a good herbal option. For deer, russian sage is said to repel them, but nothing is as effective as tall fences. For rabbits, garlics and mexican marigolds. For racoons, try placing cucumber near corn, but best is to use old nets or thorny shrubs. For squirrels, frittilary seems to work.


For brassica clubroot: your soil is probably wet and anaerobic, hence acidic. Correct pH to 7.2 or higher, add calcium. Build hugelbeds to attract fungi that controls clubroot.

For tomato and cucurbit mildew, have plants in well-composted beds near swales, to have plants very healthy and non-stressed. Keep good ventillation and avoid damp conditions. Avoid lack of calcium. For strawberries, grow alpine varieties.

For cabbage worm, plant borage nearby. Cabbage maggot is repelled by thyme. Cabbage looper (caused by larvae of a butterfly) is repelled by catnip, dill and garlic, hyssop and mint, nasturtium. Cabbage white butterfly is also repelled by tansy, wormwood in addition to many of the others. Wormwood is an excellent companion for cabbages. As are garlics, tansy and thyme.

Slugs. Plant fennel nearby.

Carrot fly is repelled by garlic family, chives for example.

For mosquitoes, plant lantana, citronella, lavender and basil. Have ducks or fish in the standing water.

To repel moths: wormwood, lavender and spearmint,

Some herbs deter really many pests! Examples include wormwood, chrysanthemus, dill and garlic, but also mint, nasturtium, thyme, and tansy.

Spider mites are said to be repelled by coriander and dill. Neem is definitively an excellent repellent. This pest appears when plants are stressed; give them the best conditions! Ventillation, air moisture and good plant health are essential.

Aphids are repelled by chives and garlic, fennel and mints, nasturtiums. Wind and washing plants also work.

In SUMMARY, a fence of garlics, frittilary and daffodils, wormwood and thyme. Fennel for slugs. Lavender for moths and mosquitoes. Possibly tansy, dill, borage and mints.
