A cross-sectional survey study was conducted from November 2015 to May 2016 in Welkait district Western part of Tigray Region. A total of 120 small ruminant owners were interviewed using semi-structured questionnaire. The survey was focus on husbandry system, awareness status of animal owners on ectoparasites and their effect, treatment approaches and an assessment on the implementation and impact of ectoparasites control intervention practiced in the study district. The current assessment showed that the production system practiced in the study area is mixed production with (31.67%) owners managed their sheep and goats independently in their own house whereas (62.5%) had been kept their sheep and goats together with other domestic animal including dog and cat. With regard to the knowledge of ectoparasites species, (100%) of the respondents clearly indicate that they knew one or more ectoparasites that affect sheep and goats. During the survey, the veterinary service delivery and the free charge governmental ectoparasites control campaign conducted was assessed. According to the response of (89.61%) respondents reported that modern veterinary service delivery had in their nearby but; the rest did not have any service. Out of 120 interviewed, (98.33%) respondents knew the free charge governmental ectoparates control program conducted from 2012 to 2015. From the total 120 intertwined individual, (94.17%) small ruminant owners sprayed/dipped their sheep and goats one or more times at different interval using acaricides (diazinone 60%). From (94.17%) respondents which had sprayed/dipped their sheep and goats, (88.49%) were used knapsack spraying option whereas (4.42%) disinfected by dipping. During the survey the interval of treatment applied was assessed. According the response (70.00%) interviewed individuals, they were treated their sheep and goats at two week interval whereas (25.00%) and (5.00%) of the respondent provided and treated their small ruminants at three and four week interval respectively. As indicated by (96.5%) respondents, there was re-infestation of ectoparasites after the control campaign. Based on these findings, designing and implementing proper annual chemical control, develop clear animal movement policy and strict quarantine, creating awareness and better management practice should be implemented.
