Problems solved by technology

[0008] When different insecticides are incorporated into a polymer matrix (such as disclosed by Vestergaard Frandsen et al. WO03 / 063587) or if different insecticides are incorporated with a synergist into a polymer matrix for a pet collar (such as As disclosed in WO06 / 1247067 to Albright), the movement of insecticides can be difficult to control because a movement enhancer or inhibitor of one insecticide or synergist may affect the movement of other insecticides

Embodiment Construction

[0027] In certain embodiments of the invention, a first portion (eg, a first type of filament) can have incorporated therein a first type of insecticide (eg, a pyrethrin) having a first speed of movement and a first insecticidal efficiency. A second portion (eg, a second type of filament) may incorporate therein a synergist, such as PBO, having a second speed of movement. In order to achieve the optimal amount of released insecticides and synergists, the first and second movement speeds can be achieved independently by movement inhibitors or movement accelerators, because movement inhibitors and accelerators are present in the line in separate parts, such as in separate filaments, without interfering with each other.

[0028] Optionally, the first portion may incorporate therein a first type of insecticide having a first speed of movement and a first insecticidal efficiency. The second part may incorporate therein a second type of insecticide, for example to combat insects re...
