Which statement is true regarding solvent-containing liquid sprays and insulation, as well as fogger efficacy against ants?

• A. Foggers are the best method to control ants indoors.
• B. Solvents in many liquid sprays can melt some insulation.
• C. Insects are unaffected by solvents.
• D. Dusts always degrade insulation.

Answer: (B)

Solvent-containing liquid sprays carry organic solvents that can soften or dissolve insulation materials. Polystyrene and some polyurethane insulations are particularly sensitive to these solvents, so applying these sprays near or onto insulation can cause damage, reduce insulation effectiveness, or create gaps. That’s why using products labeled as safe for use around insulation or choosing non-solvent formulations is important when work is done indoors. Foggers are not a reliable method for controlling ants indoors because the fine mist often doesn’t penetrate deep into nests or track routes, and ants can avoid treated areas. Residual, targeted treatments or baiting are typically much more effective for ant problems. The other statements aren’t generally true: insects aren’t unaffected by solvents, and dusts used in pest control aren’t guaranteed to degrade insulation.
