I currently have a pest company treating my home. We are seeing a few roaches and spiders every so often inside. While I could call them to come treat for free that would also mean me or my wife would have to take off work to be here. I am licensed and already have the stuff. Can't I just mix up some bifen(maybe 1-2 oz per gallon) and spray the base boards? If anyone has any tricks or app ideas that would work let's hear them. Hope things are well.
