SALISBURY, Md. - Just in case you happen to be looking for a diversity of insects, you might have more luck looking in the homes of wealthier people.
In a recently published study, researchers looked at 50 homes in North Carolina, and found that as "average neighborhood income" increased, so did the number of different kinds of insects.
It's evidence of the so-called "luxury effect," which states that richer neighborhoods tend to be more biologically diverse because they often have more elaborate gardens attracting different types of animal life.
The researchers say it also appears to apply to indoor environments, even if a home had a sparse garden, as long as the surrounding neighborhood had a lot of plant life.
The authors say the vast majority of the insects are considered non-pests, and "broadly speaking, they majority of indoor arthropods are flies, spiders, beetles, and ants."
The researchers also conclude that the public perception of low-income neighborhoods having major bug problems has been based on prejudice, rather than science.
