'Vertical forest' Residential Complex Turns Into Mosquito-Infested Jungle

Dozens of countries are trying to find new and innovative ways to make the world a healthier, happier place for both humans and nature alike.

One such example would be more environmentally friendly homes, such as Chengdu’s Qiyi City Forest Garden. This experimental green housing project in a Chinese megacity promised prospective residents life in a "vertical forest, "with beautifully kept gardens on every balcony. Essentially, residents would be waking up in their own green paradise every morning, which proved quite popular, in theory.

According to the project’s estate agent, the rower block was extremely sought after and all 826 apartments were snapped up by April earlier this year. However, instead of the luxury eco-paradise that was envisaged by so many, the towers look like a post-apocalyptic fortress, unkept and overrun by nature itself. So why had this set of flats lost their appeal all of a sudden? Well, there was an infestation. An infestation of mosquitoes. Humans love the idea of living in a city-forest but one thing that no one had planned for is the fact that mosquitoes love all the plants too!

The block of apartments has now become a desolate wasteland with only a handful of families having moved into Qiyi City Forest Garden due to the overwhelming infestation of bugs and critters, mainly mosquitoes. Built back in 2018, each private balcony was designed to provide space for plants to grow and thrive, in an albeit controlled environment.

No tenants means no one is there caring for the gardens and without any care, the eight towers have since been overrun by their own plants, as well as invaded by thousands of pesky mosquitoes. The neglected balconies have been almost entirely absorbed with branches hanging over railings, cascading down the sides of the buildings.

That said, a few residents have moved in, official numbers are still unknown but estimates say there are ten families currently living in the apartment block. A handful of balconies had pruned plants and furniture outside, as well as lights turned on inside the apartments. While it may not be pleasant for most, it clearly hasn’t phased some families who are more than willing to brave the mosquito infestation.

What started out as a brilliant idea to attract new residents and being nature back into the urban area, has since turned into a disaster with mosquitos and various other bugs raiding the towers plants and terrorising residents, pushing many away. Hopefully this won’t be permanent and once the plants are back under control, the mosquito numbers will die down and residents can move into their new world of paradise.


Mosquitoes lay eggs and larvae develop in standing water. An explosion of their population indicates a poorly designed and/or executed building that allowed pooled water to provide a breeding ground for the little vampires. Also, since the water is not part of the natural ecosystem, there are no mosquito larvae predators to keep the population in check. They could have avoided this and maybe can correct it by eliminating any place that allows water to pool long enough to hatch mosquito eggs and allow the larvae to develop into adults. This only takes a few days. Also, they could include mosquito repellent plants like citronella, lemongrass, catnip, and neem in their plant selection. Plants and animals are completely interdependent. Large concentrations of plants will inevitably attract animals looking for food, water, and shelter, including insects, rodents, birds, etc, and anything that might be hunting them. With some renovation, detailed research into plant selection and more attention paid to the complex realities of how ecosystems actually work, this development could be saved.


I have heard that Lemongrass works wonders. I totally agree that it could of been better planned out.
Need bats to eat the mosquitos at night and dragonflies for during the day.

It’s a bug’s life estates.
