​What Else Should You Consider Besides Freezing Bed Bugs?

​We've already established the fact that freezing is not really a viable option in at least curbing the fast increasing population of bed bugs inside your apartment. Because of this, you will to consider these proven effective alternatives:

Hair dryer

This may sound hilarious but the use of a hair dryer is downright effective as far as killing bed bugs is concerned. 

Hair dryers generally blast off hot air with temperatures reaching 100 to 140 degrees Fahrenheit. Set the dryer at the highest temperature setting and point it directly towards spotted bed bugs.

This simple yet effective remedy is best for those who don't have enough energy to spare for a more comprehensive bed bug crackdown mission.

Hot water wash

If you are planning on washing your bed bug infested clothes, mattress covers, pillow cases, and blankets or comforters, it's best to do it with hot water. Secure your laundry in a tightly sealed bag as you take it out of your bedroom and into the laundry area. 

Set your washing machine at the highest temperature setting. By the way, you have to first make sure that the fabrics you are about to wash with hot water can withstand the needed heat. Finish off with the hottest setting of your dryer for a sure kill.

​Vacuum cleaner

Using your vacuum cleaner is a simple yet effective method in significantly reducing the number of bed bug invaders. And in terms of the equipment, the greater the suction power, the better.
