Unfortunately there’s bad news for everyone who has a problem with bugs and that is that bed bugs developed resistance to insecticides.
Although very unpleasant even to talk about, bugs are a part of our lives and each one of us has had at least one encounter in their life with a little crawler. In order to get rid of them, besides the momentary scream and throw of the slipper, most of us use insecticides. Insecticides should be something that doesn’t only kill bed bugs but also keeps them from reappearing.
However, according to a new study conducted by a team of researchers from both New Mexico State University and Virginia Tech, some of the most common insecticides have become almost useless in our fight with the bugs, as the little enemies are becoming immune to the substances called neonicotinoids or neonics.
The researchers collected colonies of bugs from Michigan, Ohio and Cincinnati and compared them to a colony kept in isolation, which has never been exposed to the insecticide. The latter colony was killed easily once getting in contact with the neonics, whereas the other colonies showed resistance and a multiple dose of the insecticide was needed to annihilate them.
To give you a more specific idea, half of the bugs which were kept in the lab were killed using only 0.3 nanograms of the substance, whereas in comparison, half of the other bugs were killed using 10,000 nanograms of neonics.
This clearly shows that this type of insecticide is not working and therefore we should turn to other ways of fighting off the intruders. The insecticide doesn’t work and it is also pretty expensive, so other solutions should be found soon.
The problem is on the rise as more and more homes and hotels are infected by bed bugs. Being bitten can do you harm both physically and emotionally. Both companies and individuals should pay attention to their insecticides to see whether it is still performing as it should. For example, if after using the insecticide on a certain surface the bugs keep reappearing, then the substance is no longer of any good.
All in all, we hope that scientists will soon develop new ways of getting rid of bed bugs, since the current solutions are no longer viable.
