There are various types of bed bug spray available in the market. You can choose the best one according to the ingredients, the method of application, and the longevity of the effects. You can either go for a contact or residual method. Contact type will kill the bugs immediately, while residual type will kill them over a longer period of time. The disadvantage of residual spray is that the poison may transfer to other bed bugs.
Some of the best bed bug sprays are based on natural ingredients. Some of them are even made from fungus, which only affects bed bugs. Other options are synthetic ones. These include Bayer Advanced, FenvaStar EcoCap, and Bedlam Plus. It is best to use the sprays on bed frames and furniture.
You should first isolate the areas where bed bugs have been present. Moreover, you should also clean the things that have been exposed to them with hot water. If washing is not an option, you should seal these items and place them in a garbage bag. If the items are not washable, you can also use baking soda on them.
Another option is to use a biopesticide. It contains diatomaceous earth, which is a powder made from fossilized algae. This chemical makes the pests fear it. Moreover, it affects their body systems, and its smell can scare them off.
