If these houseplant pests are out of control, you can bag up the entire plant and toss it out with the trash. It’s a quick, permanent way to get rid of spider mites. Getting rid of the infested plant also prevents the mites from transferring to another one of your indoor plants. Despite their short life cycle, they reproduce rapidly, so the earlier you can control them, the better. At just 5 days old, females start laying eggs, depositing a few hundred of them during her three to four-week lifetime. These eggs only take about 72 hours to hatch.
