In yet another set of experiments cockroaches did not respond as strongly to tablets of prior art formulations containing a single or multiple formulation, and all cockroaches were away from the tablet for a longer period of time than in the first set. Therefore, the insect-repellent effect of the multilayer tablet in this embodiment is significantly improved compared to the insect-repellent tablet in the prior art. Insect repellent model test is shown in table 2 below:

example 1 is a three-layer structure, the first and second liquid absorption layers both absorb camphor essential oil, and the slow release layer comprises camphor; example 2 is a three-layer structure, the first and second liquid absorption layers respectively absorb camphor essential oil and mint essential oil, and the slow release layer comprises citronella extract; example 3 is a five-layer structure with three wicking layers to adsorb camphor essential oil, mint essential oil and citronella essential oil, respectively, and two sustained release layers containing camphor and citronella extract, respectively. Comparative example 1 is a single-layer, single-component (impregnated with camphor essential oil) tablet of the same volume size; comparative example 2 is a single-layer, multi-component (impregnated with camphor essential oil and mint essential oil) tablet of the same volume size. The test condition includes semi-closed box, sets up the division board at the intermediate position of box, and the division board lower extreme is equipped with a plurality of openings that can open and close to supply the cockroach to creep through, the division board separates the box for two parts. When the experiment began, place certain quantity cockroach in the first portion of box to close the opening, later put into the medicament piece in this first portion box, and open the opening simultaneously, the timing begins to all the cockroaches from this moment and all flees the time that first portion to second portion box required, and the unit is the second. As can be seen from table 2, cockroaches reacted most strongly to the drug tablets having the multilayer structure of the present example and adsorbing different drug components. Even though the three-layer structure adsorbs the same essential oil, the insect-repellent effect is better than that of the comparative example.
