I can't imagine using a garden pump sprayer inside...** A: Why can't you imagine a garden pump sprayer in the house? It's what professional exterminators use. A spray bottle will give you bad hand cramps by the time you are done spraying it. I couldn't imagine not using a pump sprayer inside. **Q: Will this product take care of drain fly larve?? i was told to clean drains, and use an insect growth regulator for preventive measures.** A: Yes this is great. It is the best IGR for drain flies. I recommend it to all restaurants. 1- Clean the drains as good as possible, 2- use BioDrain (an enzyme/microbe cleaner) regularly to break down the food source. 3 - Use Nyguard IGR to stop existing larvae from turning to adults. JoeEntomologist ePestHero **Q: After appling MGK nugaurd to our home when can we come back.?** A: You can remain in the home while it is being applied just stay out of the wet spray. Once dried it is perfectly safe. **Q: What effect does this have on bees?** A: NyGuard IGR is not labeled to control any form of bees and does not list toxicity for bees in the treated areas.
