This is my first time purchase of any stink bug killer product. Although, I have a contract with a pest control company .There are still some stink bugs that come in. Unlike some people I know,I did not wish to handle them up close & personal to flush them down the toilet. This product allows me to choose the 'stream' option them if they are far up, as they usually are, or choose the 'spray' option if the bug is closer. They do die in about 3 mins , sometimes a little less or if the bug is more robust will need more product to kill it.I then use the vacuum cleaner to dispose of it.This bug killer does have an odor but it does eventually go away-not very unpleasant -also i do intend to cap my chimney, a major entryway for stink bugs but I cannot imagine sitting outdoors without this product handy !
