No, Vinegar can not kill Bed bugs.
Vinegar is a weak acid which is used from centuries as a cleaning and disinfecting agent. As, it can be effective at killing some types of bacteria and viruses, there is no evidence to suggest that vinegar is an effective for killing bed bugs.
Though, vinegar is not effective at killing most types of insects, including bed bugs. Bed bugs have a hard case that protects them from external factors like vinegar, making it difficult for the vinegar to penetrate and kill them. In addition of that, bed bugs are highly resilient and can survive for several months without feeding, making them even more difficult to kill.
It is important to note that attempting to use vinegar or other household remedies to get rid of bed bugs can be dangerous and may not be effective. Sometimes people suggest using things like essential oils, baking soda, or diatomaceous earth to get rid of bed bugs.
They say these things work well, but scientists haven’t found any evidence that they actually do. In fact, if you don’t use them correctly, they could even be harmful. So it’s best to stick to treatments that have proven to work.
