4. Vinegar
5. Soapy water
6. Hydrogen peroxide

The effectiveness of these ingredients often varies based on they are used and how the bed bugs are exposed to them.

1. Isopropyl Alcohol: Isopropyl alcohol works effectively as a bed bug killer by dehydrating the insects upon direct contact. It disrupts their cellular structure, leading to their death. A study conducted by the University of Kentucky noted that 91% isopropyl alcohol is particularly effective against all life stages of bed bugs when applied directly. However, it evaporates quickly and may not provide residual protection.

2. Essential Oils: Essential oils are natural compounds extracted from plants. They can repel bed bugs due to their strong odors. For example, tea tree oil has antibacterial properties and has shown some effectiveness against bed bugs when diluted and sprayed onto affected areas. A 2018 study found that lavender oil caused bed bug mortality in lab settings. However, the effectiveness of essential oils can be inconsistent, prompting a mixed opinion on their use as standalone solutions.

3. Diatomaceous Earth: Diatomaceous earth is a powdery substance made from fossilized algae. Its effectiveness comes from its ability to absorb lipids from the waxy outer layer of insects, leading to dehydration. According to the Ohio State University Extension, when bed bugs come into contact with diatomaceous earth, it eventually results in their death over a period of time. It is considered a non-toxic option that can be safely used indoors.

4. Vinegar: Vinegar acts as a natural repellent for bed bugs but is less effective as a killing agent. The acetic acid in vinegar can disrupt a bed bug’s sense of smell, making it more difficult for them to locate hosts. While direct application may stun them temporarily, it is not a reliable solution for complete eradication.

5. Soapy Water: Soapy water can suffocate bed bugs by blocking their breathing pores. It disrupts the insects’ outer layer when sprayed. A 2015 research study published in the Journal of Economic Entomology indicated that soap-based sprays could lead to high mortality rates for bed bugs in direct contact. However, effective application requires soaking the bugs, which can be challenging.

6. Hydrogen Peroxide: Hydrogen peroxide possesses antibacterial properties and can kill bed bugs upon contact. It breaks down their external shell structure. However, careful handling is necessary as it can also bleach surfaces. A 2011 trial suggested that while it is a promising component for DIY sprays, more research is needed to establish long-term effectiveness.

These ingredients, while effective to varying degrees, should be part of an integrated pest management approach for optimal results.
