Table 2 Some challenges associated with standard IRS practices, and potential of pre-treated eave ribbons to address these challenges

From: Insecticide-treated eave ribbons for malaria vector control in low-income communities

Attributes Challenges associated with standard IRS practices Potential of insecticide- eave ribbons to address the IRS-related challenges
Quantities of chemicals Large quantities of chemicals may be needed to treat all indoor surfaces Significantly reduced quantities of chemicals will be required to treat the ribbons [36]
Spraying operations Requires removal of household belongings before spraying; this slows down operations and can limit acceptability Will not require removal of household belongings, thus can be done rapidly and at scale
Implementation teams Implementation requires large team of well-trained personnel Implementation can be done by individuals and does not require spray teams
Scalability Difficult to achieve large-scale coverage across regions or countries because of costs and logistical challenges Wider coverage can be obtained once supply chain is established
Mosquitoes targeted Targets mosquitoes spread out on indoor resting surfaces Target mosquitoes at specific points of entry [37]
Target surface IRS monitoring is sub-optimal given differences in substrates on people’s walls; varied indoor resting behaviours of mosquitoes [60], and post-spraying changes on sprayed surfaces [61] Monitoring can be standardized since the treatment substrate is standardizable
  1. The contents of this table are not meant to directly compare indoor residual spraying against and insecticide-treated eave ribbons. Instead, the objective is to identify specific IRS challenges that can potentially be addressed by using current or improved versions of insecticide-treated ribbons. Nonetheless, full determination of these attributes requires comparative field evaluation of insecticide-treated eave ribbons and standard IRS practices
