Resumo: Objectives To assess the feasibility of conducting standard indoor space spraying using ultra-low-volume (SID-ULV) in terms of willingness to pay (WTP) and ability to pay (ATP) and ability to conduct space spraying by local administrative organisations (LAO) in lower Southern Thailand. Methods Cross-sectional study. The executive leaders of each LAO were asked to state their WTP and ATP for SID-ULV. Willingness to pay was measured by the payment card and open-ended question methods. Ability to pay was calculated using the budget allocation for space spraying and estimated expenditure for SID-ULV. Ability to conduct the SID-ULV was assessed by interviewing the spraymen. Average WTP and ATP were calculated and uncertainties were estimated using a bootstrapping technique. Results Ninty-three percent of executive leaders were willing to pay for SID-ULV. The average WTP per case was USD 259 (95% confidence interval [CI] 217303). Thirty-eight percent of all LAO had actual ATP and 60% had ideal ATP. The average annual budget allocated for space spraying was USD 2327 (95% CI: 16543138). The amount of money LAO were willing to pay did not vary significantly between their different types, but ATP did. Thirty-two percent of spraymen could not complete all nine procedures of SID-ULV. Conclusions Although WTP for SID-ULV space spraying was high, ATP was low, which revealed the flexibility of budget allocation for SID-ULV in each LAO. The spraymen require training in SID-ULV space spraying.
