Mosquitoes breed in the basins beneath planter pots. In many, there is a protruding lip used to water the plant. Planter pots are generally of a two-part design with the water basin at the bottom and the plant with potting soil on the top.

Gardeners bottom water through the lip in tight-fitting basin/pot configurations or in the basin in looser-fitting basin/pot configurations. The gap, wide or tight, and the watering lips permit entry of egg-laying female mosquitoes and exit of young, hungry mosquitoes.

The solution is a strip of fabric with a mesh tight enough to prevent crossing by mosquitoes but loose enough to permit bottom watering. This is akin to an adhesive bandage and can be purpose-built to a manufactured pot or more one-size-fits-many for more generic consumer use.

In addition to this, a round version is proposed for little-used sink drains. Since water collects in the U-joint, open drains provide still water where mosquitoes breed. The drain version should be constructed with a sturdy portion that, if the adhesive fails, should prevent the patch from going down the drain (a flat metal or plastic ring or star, for example.

This invention should be easily manufactured with existing equipment with minor modifications.

The upshot is less mosquitoes, less annoyance, and should result in a reduction of mosquito-borne disease. It should make garden centers more customer friendly.
