A diatomaceous earth product such as Manna Pro Pure Defense would not be recommended for fungus gnats. Fungus gnats are usually found due to over-watering, so we would recommend to first be sure to allow plants to properly drain and dry up some to eliminate the breeding environment. You can use a systemic insecticide such as Bonide Systemic Granules incorporated into the soil of containerized plants. You can also apply a residual insecticide spray such as Talstar P over the top of the soil of infested plants.
Manna Pro Pure Defense Diatomaceous Earth is not labeled to used on animals at all. We would recommend contacting your vet for advice on how to treat fleas on a pregnant cat.
According to the manufacturer, Manna Pro Pure Defense should not be mixed with water. The product should only be applied to cracks and crevices with the use of a bulb duster or other suitable equipment.
