Most people react to praying mantises with a mix of curiosity and surprise, but you can transform that reaction into admiration by giving one a thoughtfully designed home. This guide walks through converting an IKEA ÅKERBÄR greenhouse into a functional and attractive mantis terrarium, combining practical modifications with aesthetic touches. If you love insects or want to create a living display that sparks conversation, this project balances design and biology. The idea is to keep conditions stable while showcasing the insect, so the layout, ventilation and choice of plants all matter.
My own interest grew from seeing an orchid mantis in a child’s book and imagining a display that felt more like a small botanical exhibit than a plastic kit. A Reddit maker, Enzo_Limonelli, published a detailed hack that uses basic tools and a few careful changes to the greenhouse to create a secure, breathable enclosure. The result is both decorative and functional: a place that supports a small ecosystem of plants and microfauna while making it easy to monitor temperature and humidity with minimal equipment.
Materials and preparation
Before you begin, gather the essentials for a safe and long-lasting setup. Key items include the IKEA ÅKERBÄR greenhouse, a sheet of perforated aluminum to improve airflow, and tools such as pliers or metal shears for cutting. You will also need aquarium silicone to seal gaps, cork bark and branches for climbing structures, and low-nutrient terrarium substrate to discourage unwanted growth. Add living clean-up organisms like isopods and springtails, dried moss and selected plants, plus optional items such as a LED lamp and heat mat. Include rubber pads to protect your furniture and some decorative rocks if you want a more finished look. Collecting everything first streamlines the build and prevents interruptions.
Step-by-step build
Start by modifying the greenhouse top: remove the original plexiglass panel and measure a replacement piece of perforated aluminum to fit. This creates a breathable roof while keeping escape risks low. Add small rubber feet or silicone or rubber furniture pads to the base to prevent slipping and surface damage. Assemble the greenhouse per the manufacturer’s instructions, then evaluate whether you need more ventilation. Many builders find the front flap adequate initially, but placing additional perforated panels on the sides or lower front helps keep air moving and reduces condensation.
Seal gaps on the greenhouse floor with aquarium silicone and allow it to cure — the maker recommends waiting 48 hours before adding moisture-sensitive materials. Next add the low-nutrient substrate, plant selection and structural elements such as cork bark and branches. Introduce the microfauna often called the cleanup crew — springtails and isopods — which will suppress mold and recycle organic matter. Use wire to fasten larger branches to the mesh roof, and lay dried moss across the substrate for humidity control. Finally, mount a LED lamp and, if needed, a heat mat beneath the enclosure. Once conditions are stable, you can house your mantis or other small arthropod.
Climate control and maintenance
Maintaining stable conditions in a mantis terrarium hinges on balanced airflow and gentle heating. A small fan used indirectly can help circulate air without creating drafts; the builder decided to add extra perforated panels later to improve passive circulation. Monitor humidity with a hygrometer and avoid overwatering, which invites mold. If you use a heat mat, choose a low-wattage model and place it under one side to create a thermal gradient. Regular checks to the substrate and the clean-up population help catch problems early; replacing a portion of the dried moss and trimming plants keeps the visual appeal without disturbing the residents.
Lessons learned and community sharing
One practical takeaway is that smaller, standard terrariums are often simpler to control for temperature and humidity, so expect a learning curve when scaling up to a modified greenhouse. The builder who inspired this project admitted to iterative improvements: adding more ventilation, testing live moss attachment to cork bark, and adjusting placement of decor. Sharing these tweaks in the Ikea-hacker and reptile/insect communities accelerates refinement, because other makers will suggest alternative panels, different mesh types, or varied plant palettes. If you try this yourself, document adjustments and consider following Enzo_Limonelli on Reddit to see ongoing updates — the exchange of ideas is part of what makes DIY terrarium work rewarding.
