Tiger mosquito Aedes albpictus has been spread all over the world in the last four decades, and it was first noticed in Croatia in 2004. In the area of Vukovarsko-Srijemska county, in the period from June to November 2016.- 2019. the research was taken, in which was firstly established the existence of the species in 2016, and then there was noted how much they spread and increased in their number. The former results showed how the species Aedes albopictus is easily and unstoppable spreading. Since the conventional methodes of treating mosquitos are not effective enough in reduction of this species, educating citizens to be able to reduce the number of potential litters itself seemed as one of the possible solution. In this research we wanted to get some information of the efficiency of the education, which was done with help of the educational leaflets. The research was taken in the last week of August and the first week of September 2021. on two groups of respondents in the town of Vinkovci. The first group (n1) got the leaflets while the second group (n2) did not get them. For both of the groups was used the survey with 11 questions. The survey was taken at the sample of totally 203 respondents, 109 respondents in the group n1 and 94 respondents in the group n2. The statistical processing of the results for both of the groups was done by the method of comparison with testing of the hypothesis. The responses of the group n1 were more accurate as a result of the availability of the leaflet information.The eight (8th) question was processed as a separate statistical category because all three questions are correct and refer only to the group n1. The results of the 8th question showed how 14% of the respondents answered correctly and circled all three answers, 19% circled two answers and even 67% circled just one answer. From the results of the survey, it is evident that a small group of citizens read the leaflets.
