Aphids

Aphids, aphides or plant-lice, make their presence known by the plant assuming an unhealthy appearance, the leaves curling up, etc. Frequently swarms of ants (which feed upon the aphides) are found beneath the plants attacked. Syringe the plant all over repeatedly with gas-tar water, or with tobacco or lime-water. The lady-bird is their natural enemy.
