Permethrin SFR 36.8% is labeled for roaches, so it would kill roaches of any species or size that come into contact with it via direct spray or residual. If you are only seeing roaches occasionally and need a residual spray to create a barrier, then you have many options. Temprid FX is water-based and contains two active ingredients for longer control. It also does not have the odor that sprays with permethrin will have. If you are seeing different life stages and/or seeing roaches consistently, then we would recommend our Roach Control Kit Rotation A. Please see our Roach Treament Guide for more information and tips.
Permethrin SFR 36.8% is not labeled for use on container plants so we cannot recommend it. We would recommend something like Bifen IT instead which is known for being super gentle on plants and can be used as a soil drench. The best option with fungus gnats though is to allow the soil to dry out completely as this will kill any larvae in it.
Permethrin SFR 36.8% should only be applied once every four weeks. It does take time for the product to work after applied.

Pets need to be kept out of the area being treated during application and until everything is completely dry.
