Bed Bug Repellents -Natural Homemade, Creams, Electronic & Reviews
Use of repellents is just one of the many available ways to do away with bed bugs. One factor to keep in mind is that this method won’t act as instant killer but it is only a means to deter the bugs from approaching or settling in your home. Read on to find out how these repulsive products work plus reviews of best natural and homemade repellents
Repellents are just but one of the indications of pesticides. They discourage and prevent infestations or harmful effects of bed bugs among other critters such as mosquitoes, ticks, lice, etc. Did you know that ‘pesticides’ is a term that is used to refer to not only something that is indicated to kill insects but is a broader term than you might know? Repellents are one of the two types of pesticides which do not kill the insects but simply prevents them from approaching its host. Therefore, it is not wise and expected that you use repellents to kill the offending insect. In other words, insects dump you for the better repellent as they are more attractive or scare the critter away from you. All this can be confirmed by this statement in the pesticide law as registered by EPA: that pesticides are substances that have been intended for preventing, repelling, destroying or the mitigation of any pest. There are various formulations in which repellents come in including:
Spatial repellents such as some heating mechanisms used in candles, coils, torches and lanterns.
Clip-on repellents from which the repellent chemical is dispersed near your body to prevent approach.
Creams and ointments applied topically on the skin
Electronic devices such as ultrasonic repellents
Bed bug repellents are formulated in a variety of ways that you will get to know of as you read this article.
How they work
Bed bug repellents contain specific chemicals that keep bed bugs away or from entering your space. There are very limited options to the chemical you can use to keep bed bugs away. According to the Journal of Economic Entomology’s 2013 Ed., DEET (N,N-diethyl-meta-toluamide) has been listed as the best chemical product for repelling bed bugs. Other chemicals that are in the wait list but have shown significant efficacy are 3-methyl-5-hexyl-2-cyclohexenone, propyl dihydrojasmonate and Y-methyl tridecalactone. The above chemicals need to be used in the dosages indicated in the instructions and directions for purposes of your skin’s safety. DEET, for instance, has shown strong efficacy when used in concentrations of 25%. According to the Journal of Medical Entomology, in a publication by Davis EE et al, (1985), the repellent DEET targets the central nervous system and the peripheral nervous system. There are however five propositions concerning the mechanism of action of the repellents. They:
Inhibit response of the critter to chemotactic stimuli by the host
Stimulation of a competing response that masks stimuli to host attractants.
Acts as a highly concentrated attractant hence shifting focus of the insect to it rather than to the host.
It literally ‘jams’ the sensory circuit by increasing the noise/signal ratio
Stimulation of natural avoidance receptors hence resulting in disinterest in the host.
Another theory to the mechanism of action of the bed bug repellents has found an association with olfactory receptors. DEET suppresses the bed bug reception of the smell of particular chemicals the host produces.
Natural & Homemade bed bug repellents
Homemade bed bug repellents are also options you can opt for. If you can access diatomite, then you have a good repellent, diatomaceous earth. This material can be placed on the ground and used to repel and at the same time kill bed bugs. It works by dehydrating the exoskeleton of the bed bug and hence preventing molting and therefore growth. You can also make a vinegar solution then spray it directly on the bugs. This will help repel the bed bugs for some time while you think of doing something long-term about them. In order to make this happen, you can purchase some vinegar then fill a bottle with a 1:1 ratio mixture of vinegar and water. Sprinkle in areas with bed bugs including their hiding spots to prevent their coming out.
Natural bed bug repellent-Scents & Oils
There are repellents that are scented. Most of these are essential oils such as eucalyptus or lavender oil. Note that most of these oils mentioned in this section have some menthol in them and hence this similarity raises the possibility of its acting to repel bed bugs. One good example is the lemon eucalyptus which has a derivative of menthol, p-menthane-3,8-diol (PMD) as the active compound. Some of the scented oils that you can acquire and use include:
Tea tree oil
Much of the oils that are used as repellents of bed bugs are scented as mentioned in the previous section. Lavender, peppermint and tea tree oils are the most commonly used oils. They have a cooling effect when applied on the skin and to add, are also effective in the treatment of bed bug bites. Other oils that can be used include:
Catnip oil with the active principle, Nepetalactone
Fish oil in combination with the Birch tree back
A blend of the essential oils will go a long way to providing you with a stronger repellent action against bed bugs as seen with a mixture of lavender and lemon grass or peppermint oil.
Bed bug repellent creams, Sprays & Electronic
Creams that show efficacy in repelling bed bugs include those that are herbal such as those made form neem oil or other oils mentioned earlier. Lotions are more popular as they do not adhere to the skin as much and causing discomfort when you apply right before bed time. They therefore get positive reviews. The creams and lotions confer protection from bed bugs for a few hours and they die out before the night is over hence may still allow bed bugs into your space. This will therefor force you to reapply the oil or lotion for added protection. Those that have some petroleum jelly have also been shown to be effective in repelling bed bugs.
Sprays can be indicated as a formulation in administration of the repellent chemical. However, this formulation has been shown to be ineffective as when the liquid has dried out, bed bugs win. Therefore, sprays do exist as bed bug repellents though the entomologist do not find it effective.
This method is mostly used in the elimination of bed bugs though has been discouraged due to the high possibility of potential fires when care not taken. It is possible to kill the critters with alcohol upon contact but this is not considered an option in repelling bed bugs. Its aqueous nature allows it to dry up hence not offering any benefit to the host.
This is not a new method. It has been hyped and used in a bid to repel not only bed bugs but other insects such as mosquitoes and cockroaches. The efficacy of this method has been questioned severally and studies relating to the same have been published. Comically, a study showed that instead of the ultrasonic repellent doing its job as expected, it led to an increase in the biting rates of mosquitoes. According to the Journal of Economic Entomology, this method does not work well as it has been advertised by its manufacturers. It was further found that there is not difference between the changes in behavior when bed bugs were exposed to the electronic repellent and when not. Therefore, they do not work.
Ultrasonic bed bug repeller
Ultrasonic bed bug repellent is an electronic repellent that is meant to keep bed bugs away. Just one of the methods that are currently filling the market in the name of helping people do away with bed bugs or prevent their adverse biting and discomfort. Of course, people need a solution and they will indeed purchase them. As mentioned earlier, a study published in the Journal of Economic Entomology showed that sound waves have no implication in the change of behavior of bed bugs and they simply will not go away when you are using this device. They may be effective for insects that fly and bed bugs do not. Moreover, a Flagstaff research study compared the effect of using the device with a control involving no use of the device. There was not significant change in the change of population of the two groups of bed bugs in either areas they resided. This shows that ultrasonic repellents do not work. Good thing, the manufacturers of these devices have been warned and informed to provide evidence based claims for their products by the Federal Trade Commission.
Repellent mattress cover
There are two types of such covers depending on whether they are just encasements or fortified encasements with a chemical impregnation to them. Both of these are commercially available. What is the difference between these two options? They are commonly a source of confusion. In the case of encasements, these are covers that completely cover the mattress including the box spring. This provides a barrier to the entry or escape of bed bugs and will prevent any impending bites from a bed bug. This method is particularly good when you have sprayed your dwelling or use some other elimination or treatment method and you have bought a new mattress. In the first two weeks when you are monitoring the effectiveness of the treatment method, you can encase your mattress to prevent a secondary infestation of a new mattress and box spring. This is a highly recommended method by experts and professional pest services. Mattress covers that have been impregnated are not complete encasements meaning that they do not cover the mattress completely. Neither do they cover the box spring as does the mattress encasement. They simply fit the mattress at the top and the sides. The advantage to this type of cover is that they are impregnated with an insect repellent such as permethrin. Bed bugs are therefore not able to reach you or the host as when it comes into contact with the cover, they are killed.
