How to Detect Bed Bugs in Your Home?

how to detect bed bugs what smell scares them away

A domestic scourge, bed bugs are relatively visible to the naked eye. Flattened in shape and brown in colour, these unsightly little creatures are most often encountered in the bedroom. But rest assured! They don’t jump or fly. On the other hand, they feed on blood and can sting up to 100 times in one night, causing excruciating and sometimes unbearable itching. These bites look like mosquito bites. Small black dots left on your mattress, your slots or slats in the box spring can indicate the presence of bed bugs. Ditto for blood streaks on the sheets that are the result of squashed bed bugs while you sleep. They love to hide in dark and inaccessible places. Additionally, they grow very quickly. It is enough to bring back a single female to give rise to an infestation. That is why it is crucial to get rid of them as quickly as possible!

While some smells, like bleach, white vinegar, isopropyl alcohol, and tea tree oil, scare away bed bugs, others attract them. This is particularly the case for heat and carbon dioxide that you release when breathing. Buzzing and dirt are also important factors that can explain a possible invasion into your home. To eradicate them or, better yet, prevent them, thorough cleaning and regular changing of sheets are required. Likewise, you can also rely on the following natural repellents!

Essential Oils

When these unwanted intruders invade your room, the usual solutions can be either burdensome or too expensive. No need to invest in chemicals to keep bed bugs away from your property! Several essential oils are very effective against this plague. Among the most popular are clove, tea tree, aspic lavender and java lemongrass. Here is our bed bug repellent recipe to scare them away once and for all!

  • 20 drops of tea tree essential oil
  • 50 ml of water in a spray bottle

Spray the mixture on infected areas and remember to shake before each use. Ten drops of clove essential oil will also do the trick.

Be careful, though, this natural bed bug repellent is prohibited for pregnant women and small children!

Baking Soda

Baking soda can also help. Powdered or diluted in water, sprinkle it around places where insects can nest and wait. Repeat the procedure a few days later. Please note: it is important to remain vigilant for a period of 2 months after treatment to ensure the total eradication of this plague.

White Vinegar

Thanks to the acetic acid it contains, white vinegar is a product that bed bugs cannot tolerate. In addition to the smell that scares them away, white vinegar has the power to destroy their shell, thus leading to their death. The same goes for bleach and isopropyl alcohol. The only downside is that all these odours will not eliminate bed bugs in one go. The treatment must therefore be repeated every week, or even every few days.

Coffee Powder

To benefit from it, two variations are available to you: either sprinkle the infested area with coffee powder, or dilute it in a little water, then spray the corner with it. Repeat the process a few more times and wait for the insects to absorb the coffee.

Isopropyl Alcohol
