Basil Plant Pests

Herbs generally don't suffer from pest infestations; their aromatic scent gives them an inherent protection. However, that is not to say that basil is pest-free; there will always be general garden pests requiring a feed.

Aphids

• Aphids come in the form of a tiny, winged black or green fly. They suck the sap and are particularly drawn to the new, soft, green growth of a plant. Fortunately aphids have many natural predators; introducing ladybugs and lacewings to the garden can be particularly beneficial.

Beetles

• The flea beetle is more commonly associated with brassicas and other ornamentals. However, a peppering of holes appearing on the basil could mean a flea beetle infestation. A skeletonized leaf could mean the plant has been infested with Japanese beetles. Planting hot peppers nearby can protect basil from beetles.

Slugs and Snails

• Slugs and snails can leave holes in leaves and stems and are particularly attracted to new growth. Slime trails can confirm the presence of the pests. Barriers of slug pellets or copper flashing can be laid to repel them or traps can kill them.
