This study is formal, the majority of insects will be gone in just 100 years

They come into force again, but for how long? It’s the insects that, let’s face it, are not always welcome during our barbecue evenings! Perhaps they are unpleasant to humans, but they are essential to the ecosystem, but insects can disappear from the planet and there is an urgent need to protect them. In a report from 2019 published in the journal Science Direct and authored by Francisco Sanchez Bayo, a researcher from the University of Sydney, the scientist predicts their disappearance in 100 years. Clearly, if the scientist’s prediction were to come true, it would be a disaster for the planet. We have the power to protect some of them, but we still need to know how to tackle it. We will explain everything to you.

What does this scientific report say?

The report reviews the various most endangered species and the causes of these threats. We learn, for example, that more than 40% of insect species are endangered of extinction and that it is hymenoptera, coleoptera (dung beetles), lepidoptera that would be most affected. Aquatic species are also endangered, and this would be partly to blame for intensive agriculture, which has destroyed their habitats. In Europe, certain pesticides are now banned, but this is not the case everywhere in the world and this would be the second threat to insects. Finally, climate change and the strong growth of invasive plants will be further causes of threats to our insects.

How to protect insects on a daily basis?

The first thing you need to do is stop using pesticides in the garden, this is nothing new … Normally there are no more sales of chemical herbicides and other pesticides, but if you have some left, drop them off at the recycling site, but please banish them from your kitchen gardens! You can use bark chips, compost etc. attach certain plants to repel them, but pesticides kill them! As for plants, you knew that certain flowers and aromatic plants are insect “rescuer”? Plant lavender, rosemary, sage, sunflower to feed the bees that are disappearing at a tremendous rate.

You can also sow flower beds in a corner of your garden: bees and butterflies will have a field day. How about installing or building an insect hotel? These little wooden houses are pretty easy to make with scrap materials and you will find many tutorials online. Insect hotels are popular havens for solitary (or wild) bees, which unlike honey bees do not live in colonies or hives, but which are just as essential for pollination. Finally the last piece of advice that may seem obvious: do not kill them! Ok, you may be entomophobic, but the little beast has never eaten the big one!

How to install an insect hotel?

Whether you are building it yourself thanks to this kind of tutorial, or whether you are buying it already built, here are the few rules you need to follow to install it. A few boards, earthen pots, a few squares, some time to set aside for construction, and you’re done!

  • The entrance to the hotel must be located to the south / south-east to be in the sun maximum during the day.
  • It should preferably have its back to the prevailing wind.
  • If you have sown a flower meadow, place it oriented in the middle of the meadow.
  • If you place it on the ground, install it on the brick for protect it from moisture. If you can, install it on a stand or hang it on a tree …
