Pest Problems

The beneficial nematode Steinernema kraussei and provides a rapid curative control of black vine weevil. It has the added advantage of being cold-temperature tolerant. Will control black vine weevil larvae in soil temperatures down to 41°F.

The wasp genus Aphidius is a large group containing numerous species, all of which attack aphids and provide natural control of aphids in backyard gardens, commercial fields, and urban landscapes. They are generally used in greenhouses.
Aphidius colemani are small braconid wasps. Females lay eggs singly in aphid nymphs. The wasp larvae consume the aphids from inside. As the larvae mature and the aphids are killed, the aphids turn into mummies. After the larvae pupate, each adult wasp emerges through an exit hole cut in the mummy. In addition to killing aphids directly, mechanical disturbance of aphid colonies by the searching behavior of the adult wasps causes many aphids to fall off the plants and die.

Three species of predatory fly parasites mixed in your order: Spalangia cameroni, Muscidifurax zaraptor and Muscidifurax raptorellus.
Fly parasites are an effective natural enemy of flies. Frequent releases of fly parasites can drastically reduce common housefly and stable fly populations. Fly parasites search fly-breeding areas for fly pupae containing developing flies. Once a fly parasite finds a pupa, it drills a hole through the casing and inserts several eggs through the hole.
Once inside, the eggs hatch inside the fly pupa and feed on the developing fly and after two to three weeks of feeding, an adult fly parasite emerges to repeat the cycle. Each female fly parasite can kill approximately 100 immature flies in her lifetime.
