Query: Safe bug killer

No more bed bugs. It took a week before I notice a reduction. I also used this on roaches. It doesn't kill on contact. The smaller bugs die within 20 seconds. The larger ones have time to run away and hide. Which is good. They can carry it back to their nest. It has a mild organic smell. It will leave a sticky film if you don't wipe after spraying. I bought 2 more bottles for the rest of the house.
