How do you keep Giant Shield Mantis?

Housing requirements differ depending on the mantid size. Keep small nymphs in 32oz plastic pots or similar. Keep large individuals in one of our praying mantis kits or a large plastic sweet jar. Give consideration to the ventilation you provide. Use fine netting over smaller pots and glue metal gauze in place in larger plastic containers. If you decide to use a plastic faunarium or glass terrarium instead, then you don’t need to worry, as they are already well ventilated.

Maintain temperatures between 22-26°C daytime, preferably with a nighttime drop. Keep humidity around 70-80%. Like most mantis species they are quite tolerant of being kept at normal household temperatures with no additional heating, as long as they’re kept out of direct sunlight or cold drafts. Humidity is often over emphasised with invertebrates and too much can have devastating effects. Misting the side of the enclosure and décor items 2-3 times a week with a hand sprayer is often more than adequate for this species.

Décor and substrate is a personal choice. You can use something as simple as a trailing piece of tissue down the side of the pot for them to climb on, or be creative and add lots of twigs, branches, live or artificial plants. Peat based substrates and mosses are commonly used on the floor of the enclosure and will obviously help with maintaining relative humidity.

Offer small nymphs fruit fly. Once they have reached 3rd-4th instar or above, try offering alternatives such as crickets, locusts and curly-wing flies. Larger nymphs and adults are best maintained on the larger sizes of feeder insects.
