Compositions for inhibiting the scent tracking ability of mosquitoes in environmentally defined three dimensional spaces

A composition for inhibiting the ability of mosquitoes to sense a target within a three dimensional environmental space having a land or base surface area, the composition comprising:

• (A) at least one inhibiting compound selected from the group consisting of 3-methyl-1-alkene-3-ols of the formula:
• 7
• and 3-methyl-1-alkyn-3-ols of the formula:
• 8
• wherein R1 and R2 are each independently a saturated or unsaturated aliphatic hydrocarbon group containing from 1 to about 12 carbon atoms, in
• (B) a base vehicle comprising a porous or waxy medium, the composition being capable of dispensing from the composition into the atmosphere of the three dimensional space the at least one inhibiting compound in an amount sufficient to provide an inhibiting effective amount of the at least one inhibiting compound sufficient to inhibit the ability of mosquitoes to sense a target in the three dimensional environmental space.
