I'm debating between Talstar P and Essentria. What is the difference between them for killing the large spider population living outside around the perimeter of our house? Today I noticed there were hundreds of baby spiders crawling up the foundation and siding so we need to get something and start treating immediately.
Essentria IC3 is an organic insecticide and will last only approx 2-3 weeks due to natural ingredients will break down quicker in outdoor elements. You will have better results using a synthetic pyrethroid insecticide such as Suspend SC. Suspend SC will last you 30 days outside and 90 days on the inside of the home. Spraying the perimeter of the home 2-3ft up and 2-3 ft up from the foundation and focusing on windows, doors, and entry points to the home will help. You also want to trim any bushes, shrubs or trees back from touching the side of the home. Please watch the video on the Suspend SC for application tips and directions.
