Nose pleasures Here are some inexpensive ways to bring fragrance into your home: Plug-in oil diffusers. Plugged into a standard electrical socket, these disperse scent 24/7 for four to eight weeks. Most brands offer refills, and some come with a night light, as well. Stick scents. These scented stick diffusers don’t need to be plugged in, lighted or watched. Simply open a bottle of scented oil and insert porous bamboo sticks, which allow the scent to evaporate and emit fragrance into the air. Flip the sticks weekly for four to six months. 160Want local news?Sign up for the Localist and stay informed Something went wrong. Please try again.subscribeCongratulations! You’re all set!
