Adding bark or mulch to landscaping beds is a great idea to beautify your landscape, keep the weeds down, and retain plant moisture. Yet, it can create unwanted pest problems if you’re not careful.
Remember to keep about 3 inches of clearance between the bottom of your siding and the mulch. You should be able to see your foundation. Bark, mulch, soil, etc. which extends over and “buries” the siding tends to hold moisture in and rot your siding.
This creates a highly desirable conducive condition and a direct access for termites and other wood destroying organisms. Consider having the immediate perimeter of your house sprayed after your bark/mulch has been laid. This will offer protection against organisms which may be within, or attracted to, the purchased product.
