Objective. The study aimed to establish the knowledge, attitudes, perceptions and practices of households in Quezon City on the novel dengue Ovicidal-Larvicidal (OL) traps.

Methodology. This is a descriptive cross-sectional study done in one barangay in Quezon City.  This barangay was purposively chosen for two reasons: 1) it has a  high incidence of dengue and, 2) it is one of the recipient barangays of DOST-developed OL traps distributed by DOH. Data were collected through face to face interview using a pilot-tested interview schedule and observation. Respondents were also purposively included if they were a resident of the barangay, at least 13 years old, have received an OL trap & instructions, and gave consent. A total of 399 respondents were recruited which was more than the computed sample size  of  383.

Results. Of the 399 respondents, 92% were females, age ranged from 13 to 82 (mean of 39), 85% were married and 54% finished secondary education. Majority had high level of knowledge on OL traps components, properties, installation, and maintenance. Generally, 65% to 90% of respondents had favorable attitudes and perception towards dengue OL traps. Some misconceptions like OL trap is not safe to human and that it can kill mosquitoes even without adding the pellets were found.

Conclusions. The study generally established good knowledge, positive attitudes and perceptions and correct practices among respondents. Misconceptions need to be corrected to increase the acceptability of using the OL traps at the household level.
