Cypress and cedar mulches are not just great to have around because of their red hue -- they're also a great pest deterrent! Sure, the rich red and orange shades will keep your landscape beds looking fantastic all year, but the pest control is the real winner in this group of mulches. While they put off a pleasant aroma, which can only add to the aesthetic of your landscaped area, they also work as a pesticide of sorts. The smell of these mulches will keep away insects and reptiles that would attempt to eat or injure your plants. With cedar or cypress mulch, you will have a great looking bed year round. Mr. Mulch sells bagged cypress and cedar mulches.
