A new study shows that bugs and arthropods usually prefer rich people’s houses, regardless of their high standards. The creatures live indoors and most of the time they are harmless.
The research is based on an earlier assessment made on 50 homes from North Carolina. This time, the biologists wanted to know what causes the biodiversity in the indoor bugs.
Bugs Biodiversity Study
Previous studies explained why richer neighborhoods had a wide range of animals, as they had enough money to invest in landscapes and plants. They seemingly created a perfect outdoor habitat for lizards, bats, and birds.
The leading author of the current research says that the public perception ties arthropods with low-income neighborhoods, a fact that is not currently true. Until now, the studies focused on bugs that were considered to be pests, such as bedbugs and cockroaches. However, no one tried to assess the indoor biodiversity.
The 50 houses from Raleigh offered a multitude of bugs. The scientists took into consideration only taxonomic families, which in every home reached a number between 25 and 125.
The researchers combined the arthropod information with the mean income, the surface of the house and the vegetation.
Obviously, the larger houses also hosted a diverse population of bugs. However, the surface was not the only factor.
When it came to the income, the scientists observed that rich people tended to have more species of bugs. The cause would be again the presence of green space, which can be a habitat for the insects that later move indoors.
The explanation can extend to all people living near gardens and public parks, as the bugs can easily live in a rich person’s garden and then move to its less fortunate neighbor.
Scientists warn that the biodiversity in a house situated in the Mississippi rural area can be quite different from the one that can be found in a Manhattan home.
Another limitation of the study was that all homes were freestanding houses, which means that their owners were middle-class or high-income individuals. No data on the units from apartment buildings.
Similar investigations were done in San Francisco, Sweden and even in the Peruvian Amazon, and scientists plan to extend their research in Madagascar, China, and Australia.
The biologists want to convey the idea that it is safe to have biodiversity in your home and that we need to learn from our grandparents that humans can live with other creatures such as crickets without being in any danger.
