Caterpillar Killer contains nematodes for the biological control of caterpillars.
Caterpillars develop from the eggs of moths and butterflies, some of them can cause significant damage to plants. Cabbage white caterpillars can cause extensive damage to plants like brassicas and nasturtiums. Other Caterpillars produced from moths such as Silver Y moths and Diamond Back Moths can also cause signifacant plant and crop damage. Caterpillar Killer nematodes can be used to control these caterpillars by applying them directly onto the caterpillars. Nematodes are sensitive to sunlight and need to find and penetrate the caterpillars within a few hours of application. For this reason it is important not to apply in bright sunny conditions. They also need moisture and should be applied with plenty of water. Once the nematodes come into contact with the caterpillars, they enter them releasing a bacteria that kills the caterpillars. Infected caterpillars die within a few days turning yellow to light brown and become slimy.
When high numbers of caterpillars are present repeat applications of nematodes may be required.
The standard pack of Caterpillar Killer contains 1 x 25 million nematodes treating up to 35 sq metres.
The large pack contains 2 x 25 million nematodes providing two treatments for area of 35 sq metres or a single application to total area of 70 sq metres.
