How to keep Thick-backed Spurge Family Ants?

Time spent At least: 420 days

Small groups of 1 to 20 workers

Use water-plugged test tubes or small plaster nests for culture. Maintain the temperature at 25~30 degrees Celsius, provide high humidity in the nests, and place the nests in a dark environment to wait for the queen ants to lay eggs. Maintain weekly feeding frequency and use vegetarian feed, mini breadworms and fig seeds to feed the ants. Population growth is slow at this stage.

Medium cluster 20-40 workers

Use small plaster nests for culture. Maintain the temperature at 25~30 degrees Celsius and provide high humidity for the nests to avoid disturbance. Maintain the feeding frequency at 1~2 times per week. Use vegetarian feed, SS red cockroach, mini breadworms and fig seeds to feed the ants. Population growth is faster at this stage.

Mature communities 40-100 workers

Use small plaster nests for culture. Maintain the temperature at 25~30 degrees Celsius and provide high humidity in the nests. Maintain the feeding frequency at 1~3 times per week. You may use vegetarian feed, red cockroach (No. S), mini breadworms and fig seeds to feed the ants. At this stage, the population growth rate slows down and breeding ants begin to appear.

Frequently Asked Questions

What's the time of the wedding?

Marital behavior has not yet been observed in the thick-backed spiny family ants. It is common for newborn queen ants of mature colonies to leave their nests with a small number of worker ants after mating to develop a new colony.

Where to Catch Thick-backed Assassin Ants?

Thick-backed Spiny Family Ants are only found in the southern part of the island and some of the outlying islands. They cannot be harvested through nuptial flights and are therefore extremely rare.

Is It Good To Keep Thick-Backed Stinging House Ants?

Do you want to control the temperature of your house ants?

It can be kept at 24~26 degrees Celsius with temperature control. If the temperature does not exceed 32 degrees Celsius, it can be kept in a stable environment with good ventilation. (Hedgehog family ants are only found in the southern part of the country where the temperature is higher.)
