Other natural ways to kill bed bugs

By natural ways to kill bed bugs, we mean some of the best ways to deter them from infesting without having to resort to harmful chemicals and pesticides. As such, we shall be featuring some of the best home remedies that will surely keep off those bed bugs at an instant.

1. Vacuum

With a high-power vacuum and hose attachment, it is very easy to suck up those bed bug eggs and adult bed bugs from clothes and beddings.

Be thorough in vacuuming not just the common niches of bed bugs but also furniture, cushions, and even corners of the home that are hard to reach.

2. Steam cleaning

For harder to reach areas, steam cleaning is a formidable choice. Note that bed bugs cannot survive in temperatures of more than 140F. Always follow the instructions from the steam cleaner’s manual so as not to damage the furniture.

3. Regular laundry of clothes and beddings

It is also important to regularly wash your clothes and beddings. It is also noteworthy to invest in fabrics that can tolerate steam washing or tumble dry for them to become more invulnerable to bed bugs. Also, after home treatment of bed bugs, steam wash all those that were exposed to bed bugs.

4. Silica gel

We always see this stuff in the boxes of new pairs of shoes and oftentimes, we take them for granted. But you can save these silica gel packets and then grind the beads up until they become powdery. Spread them on suspected niching areas and see the result.

5. Rubbing alcohol

While this is always contested, it is said that spritzing rubbing alcohol on bed bugs shall kill them on instant contact. If you are looking for a non-harmful and instant intervention for bed bugs, it would be through rubbing alcohol.

6. Scented dryer sheets

While this one is more of a temporary fix, it still helps to know that there is another instant intervention to bed bugs. For some reasons, bed bugs and mosquitoes hate the smell of scented dryer sheets.

On a more unfortunate end, the pesky insects shall only look for spaces where the scent from the dryer sheets cannot be smelled.

There are also herbal remedies for bed bugs if you are more on the organic side of things. Aside from the essential oils which we mentioned here, it is also notable to look at other herbal remedies which you can use as bed bug intervention if you have a supply of these around.

Lavender: Even if you do not turn lavender into essential oil, the mere scent of the plant in the home would repel bed bugs at an instant. Spreading crushed lavender leaves in crevices or washing clothes and beddings with lavender scented soap would be effective against bed bugs.
Peppermint leaves: This one works like lavender. Crushed peppermint leaves can be left in suspected bed bug niches. Just do not forget to vacuum them off the next day so as to maintain the cleanliness of the home.
Black walnut tea: This one is truly considered as an insect repellant. You can crush the leaves and put them in tea bags and then strategically place them in bed bug infested areas.
Sweet flag: This one is a rare plant, found in wetlands. But when it comes to effectiveness against bed bugs, they are one of the most potent. They can be mixed in essential oil solutions or just depend on the crushed leaves of the sweet flag plant.
Bean leaves, Indian lilac leaves, mint leaves: These three are the other herbal remedies which work like lavender and peppermint. They are better deterrents with their crushed leaves but of course, you could also always extract off their oils to make an essential oil solution.
Thyme: Aside from the leaves, it is said that thyme sticks could be wrapped around the cabinet where you keep your clothes and bedding. Some even go to more extreme ends like burning thyme leaves or sticks with cloth and then have the smoke penetrate the home for a moment to ward them off permanently.
Beauveria Bassiana: This one is a parasitic fungus which particularly feeds on insects like bed bugs. When the bed bugs are trapped in this fungus, they shall be immobile, infertile, and shall be unable to feed.
Citrus: The acidity of citrus fruits and plants do not just repel bed bugs but actually kill them in the process. If you want a bed bug egg level intervention, using citrusy scents would be the most perfect natural intervention.
