Abstract: A removable substrate for an insect attractant device includes a body having at least one surface, an upper region, and a lower region below the upper region. The upper region is configured for handling or positioning the body. The lower region includes at least one first lateral region having a first internal lateral edge and a first external lateral edge, and at least one second lateral region having a second internal lateral edge and a second external lateral edge. A gap is defined between the first and second internal lateral edges. A spacing between the first internal lateral edge and the first external lateral edge defines a first width. A spacing between the second internal lateral edge and the second external lateral edge defines a second width. The gap differs from at least one of the first width and the second width. An adhesive is disposed on the body.

Abstract: An insect control device includes a first substantially non-permeable surface having a first critical surface tension value. An insect control volatile agent is disposed on the first surface and has a surface energy at least about 5 dynes/cm2 less than the first critical surface tension value.
