If a pest control specialist or exterminator used chemicals to eliminate pests, wait a few days before doing any deep cleaning. Household chemicals like bleach and hardwood cleaner may counteract the treatment or make it less effective. Post-treatment, make sure you keep trash bins empty, sinks dry, and don’t leave any food or rubbish out. It’s time to break any habits that may have encouraged pests before, so don’t resort to old routines!
