Spiders are diverse, highly resilient, and have a strong survival ability. With just the basic needs of food, water, and shelter met, they can grow, develop, and reproduce normally. A single spider can produce 200 to 300 offspring per year, with some species producing thousands, making them highly valuable. Spiders primarily feed on insects like flies, which are easily accessible. They can be bred in self-sustaining systems without significant investment. Additionally, they can be introduced from agricultural areas, offering considerable profit potential.
Liu Jie and Liu Huimin from Weiwang Township, Cao County, Shandong Province, successfully started spider farming. They are involved in breeding, collecting, processing, and selling spiders. Since April 1997, they have earned over 100,000 yuan in net income. To help farmers and breeders better manage spider farming, their experience is now shared below:
First, choose the right spider species for breeding. It's best to start with local breeds. High-value spiders include tarantulas, black widow spiders, good-looking argiopes, and cave-dwelling tarantulas. Non-venomous species like Chinese tarantulas and big-circled spiders also offer high economic returns. Large-scale breeding of tarantulas can bring even greater profits. Liu Jie and Liu Huimin mainly raise burrowing wolf spiders, larynx spiders, big-bellied spiders, white-fronted giant crab spiders, and tarantulas.
Second, select appropriate breeding environments and tools. Indoor or outdoor setups can be used depending on scale. For small-scale breeding, wooden boxes, cement ponds, or simple shaded areas work well. For more controlled conditions, glass jars, cans, or specially designed cages can be used. The design of the cage should allow spiders to climb, hide, and move freely.
For example, using a cylindrical container with a wide mouth, you can secure it with double-layer gauze and add small sticks or paper strips inside for climbing and hiding. Another method involves a three-dimensional cage made of plastic mesh or wood. Each cage is about 20 cm in size, with an access hole covered by a cloth bag. These cages can be stacked vertically to save space. A 20-square-meter area can house up to 1,000 spiders.
For burrowing spiders, a pond-style setup works well. Bricks are used to create a 50 cm x 50 cm pit filled halfway with soil. Artificial caves are built, covered with wire mesh, and equipped with small observation and feeding doors. This method is ideal for raising tarantulas and burrowing wolf spiders.
Third, feeding methods vary based on spider type and size. Individual spiders can be raised in small containers, while groups require larger enclosures. To prevent cannibalism, add stems or branches to reduce direct contact. Only spiders of similar size and species should be housed together to avoid dominance issues.
Spiders are primarily carnivorous. They thrive on insects such as aphids, cockroaches, moths, flies, and mealworms. For large-scale operations, setting up an insect farm is recommended. Liu Jie has established a fly-breeding farm. In addition to live prey, artificial diets like milk or egg yolk can be used once a week to supplement nutrition.
