This experiment is intended to study the efficiency of wood vinegar. Of all fleas in the laboratory and outside the laboratory. Using a randomized complete plans (Completely randomized disign: CRD) two experiments. The experiment in the lab by bringing ticks, the number of 500 samples into jars that have been designed to be ventilated well jars 10 letters, divided into 5-10 treatments repeated experimental laboratory section (on the co) By Mark tick on a co 5 treatments, both to try treatments are as follows: 1 treatments, spray with water (control), 2 treatments with extracts of wood vinegar concentration of 10% for 3 treatments with extracts of wood vinegar concentration 20% 4 treatments sprayed mo.Wayasansakat smoked vinegar with 30% concentration of 5 treatments sprayed with wood vinegar concentration extract 40%, to collect information about every 12 hours in the laboratory and storage every 6 hours outside laboratory results, it appears that the wood vinegar concentration at 40%, it is best to kill ticks, unlike wood vinegar concentration 30% 20% 10% 0% the more significant statistically (P < 0.05) both inside and outside the laboratory. This experiment suggests that the aggressive wood vinegar to kill fleas.
