Understanding Bed Bugs

Bed bugs will stay anywhere they want as long the place is warm and comfortable for them. Unlike other insects and pest who prefer to reside in untidy places, bed bugs will choose to stay in an apartment, condo, hotel, and even in a mansion. The scary thing is, there might be residing in your bed right now. And you will not be aware of the infestation unless they start leaving itchy red marks in your skin.

In some case, it is hard to spot bed bugs because they can be very small. They can grow to be 5 mm in length. Also, is easy for bed bugs to reproduce as they can lay 5 eggs a day. If there are plenty of bed bugs residing in your bed, imagine how many eggs they can lay each day. You will not have the chance to kill their eggs because the bed bugs are smart enough to hide the egg in the smallest spaces. Usually, they hide their eggs in the crevices and cracks.

It will take at least two weeks for the bed bugs to hatch their eggs. Upon hatching, they will look for the perfect host in which to feed from instantly. Young bed bugs are referred to as nymphs or youngster and they are usually yellow-white in color. In just 4-5 weeks, these youngsters will start adulthood journey.

Best Residual Bed Bug Spray: Why Insecticides are More Effective than Natural Product

Despite the threats of using insecticides, the majority of homeowners prefer using such product over natural bed bug killers. This is primarily because insecticides have long term effects and they instantly get rid of the bed bug without waiting for days. On the other hand, if you want to completely get rid of the bed bugs using insecticide, they must reside in the treated surface for several days. This is crucial especially if you are planning to use residual insecticides. For this reason, it would be best to apply the chemical where bed bug infesation is likely to happen, crack, crevices, corners, and areas under skirting boards.

While several chemicals are effective in killing bed bugs, remember that the product may not get rid of their eggs. The eggs of the bed bugs are the most difficult to eradicate simply because their parents are smart enough to hide them in smaller places. It is the natural instinct of every parent to protect their child from possible harm. Aside from that, another reason why they are hard to get rid of, is because of their outer shell. It protects them from insecticides. That being said, it is possible that you killed all the bed bugs but not their eggs.

Luckily, there are residual bed bug sprays that also target the eggs. In some cases. plenty of repeat treatments must be done to make sure that all the bed bugs and eggs are killed.

If you think that all the bed bugs are all gone, do not be so sure because some are just hiding in smaller areas. According to studies, it is best to apply both the insecticide and infestation prevention methods, like removing the beds, mattresses, and other sites.
