Mosquito-control audit flags missing contracts, billing questions and sole-source purchases

The audit of the mosquito-control program identified several gaps in documentation and controls. The auditor said he could not find appraisal or supporting records for a 2007 aircraft purchase of $231,000 from Southern Seaplane Incorporated and recommended the parish document the rationale for sole-source or single-vendor chemical purchases.

Committee members also pressed whether outside billing by Infamark altered where money is held and how collections are reconciled; finance later advised that mosquito-control fees are received and deposited by the parish finance office, though the auditor recommended follow-up verification. The audit recommended that mosquito control use the parish public-request form to document complaint responses and that departments keep ending-inventory calculations to support budget planning.
