Depending on the conditions, bed bugs can survive in a plastic bag for several months or even longer. This is dependent on how sealed the bag is, the temperature inside, and the date when the bugs last fed. But in general, a sealed bag can protect bed bugs for about two to six months.
The first thing to do if you notice any signs of bedbugs is to contact a professional pest control company. While it is true that heat can kill them, it is important to be very thorough and ensure that the heat gets into every nook and cranny of the infested area. If this does not work, you may have to call an exterminator.
Another way to kill bedbugs is to use a vacuum cleaner. The bag will trap the bed bugs, but you must be extra careful to avoid the vents. Otherwise, the bugs will survive. In addition to the bag, you can use a regular trash bag to collect them.
Bed bugs can survive without food for up to a year. Their life cycle consists of five stages. Young bedbugs must feed more frequently than adults. They can live up to a year without food, while adults can survive anywhere from 20 to 400 days. A bedbug can lay 200 to 250 eggs in its lifetime.
