Gnat Bat is completely unique in that we use a complex matrix of micronized diatomaceous earth and infuse this into highly porous, lightweight volcanic rock. 

This allows gardeners to easily remove the Gnat Bat from their pots to water a plant (extending the product’s life) or to reuse the barrier in another pot.

Avoid getting Gnat Bat wet, as this reduces its ability to create an effective barrier. 
If plants require watering while undergoing treatment, simply remove the Gnat Bat barrier and replace it down once soil surfaces are dry.
