Netting
Fine mesh netting, draped over rows of vegetables, became the first line of defense. This wasn’t just a barrier, it was a visual deterrent, preventing moths and butterflies from landing and laying their eggs. The netting allowed sunlight and rain to penetrate while keeping the caterpillars out. The result was a protected haven, a miniature ecosystem where the plants could thrive without the constant threat of defoliation. The effectiveness relied, however, on proper installation, ensuring that there were no gaps or tears that could allow entry. For example, cabbage moths could lay eggs on the cabbage and those eggs, in turn, damage the cabbage crop.
-
Plant Sleeves
For individual plants or small shrubs, plant sleeves offered a targeted approach. These simple cylinders, made of breathable fabric, shielded vulnerable foliage from caterpillar attacks. The sleeves acted like miniature greenhouses, creating a slightly warmer and more humid environment that could, in some cases, accelerate plant growth. These plant sleeves protected the plant from many threats. Plant sleeves are a more direct approach.
-
Sticky Barriers
Applied to tree trunks or the stems of vulnerable plants, sticky barriers presented a more active defense. These non-toxic substances trapped caterpillars as they attempted to climb, preventing them from reaching the foliage above. Sticky barriers require regular monitoring and maintenance, as they can become coated with debris and lose their effectiveness. They provide an extra layer of protection against infestations.
-
Row Covers
Row covers, larger versions of plant sleeves, offered protection for entire rows of crops. These lightweight fabrics, supported by hoops or frames, created a physical barrier against caterpillars and other pests.
