If you’ve used a bed bug spray, you’ve probably wondered how long after the treatment is safe to enter your home. Generally, bed bugs can remain dormant for about a half-year, but this isn’t always the case. For example, they can survive in sub-zero temperatures for several days, but that’s not practical in most housing situations. This is important information for anyone who is trying to get rid of a bed bug infestation. The reason is because you may think that all of the bed bugs have been killed but in reality, a small population could still be active weeks or months after the treatment is finished.
If you’re spraying for bed bugs, you should follow the after-treatment instructions carefully. It’s important to monitor the treated area for at least two weeks after the treatment. This is so you can monitor for any new bed bug eggs. If you’re able to monitor the treated areas, you can prevent a new generation of bed bugs from infesting your home.
If you have an infestation, you should avoid using the affected area while sleeping. Sleeping on the couch encourages bed bugs to breed and feed. It’s best to sleep in the bed. The spray used to get rid of bed bugs will work for weeks after application. It will not harm your skin or hair, but it will kill the bugs and their eggs.
