Question: Does this work on flies that come in contact with it?  Like on walls?
Document: I needed to do something right away. I tried all the natural hoo-haw  since I have a one year old baby, but I didn't have the patients for it. I wanted these suckers gone! I sprayed my entire house wall to wall, all sofas and carpets, hardwood floors, curtains, anything cloth-like that would possibly come in contact with them. Then we left the house for a few hours. The next day I only saw about 3.
No not at all, I will not buy this ever again it didn't work not one bit!!! It was like I just gave my money away!
It seemed to do a good job in the house as haven't seen much live insects walking. Only very few dead ones here and there. However sprayed it in the garages all around walls and corners were there were plenty of spider webs - it did the work for a couple of weeks but shortly enough spiders were again noticed in areas that were well sprayed. Need something stronger.
Because torching my house didn't seem like the smartest option and i'm sick of sharing my beautiful home, i requested a refund and am on my way to get some more Raid Bug Barrier. (Oh btw...had to fight off a roach to get the barcode numbers while asking for a refund. It was an awesome way to start my morning). I'm not saying it doesn't work for anyone. Obviously by the good reviews, some have had success with this.
I like the electric pump spray, but this perimeter story does NOT work against Carpenter ants at all. The Carpenter ants just kept coming, no matter how much I sprayed.09/3/13 update:  TERRO 2oz Liquid Ant Killer drops on tinfoil where they were walking and it worked. That liquid stuff really works. Just add a couple drops in front of trails on tinfoil every day.
I apply this every 6 mon & when used in tandem with Terro ant baits I never have ants in my house. Even the stray aunt that does come in I giggle & point at knowing that its going to DIE! MUAH HA HA! :)
If you have pests, grab this stuff - don't even think about it! I've been using this for at least 12 years and it keeps out everything. If you have a huge ant problem, however, call an exterminator first because it will take them about 4 months to get rid of them all. Really. They build their nests in the walls of your house and well, sleep there and multiply over the winter.
I have used Home defense for years... I use the granduals along with the spray mostly as a peremeter defense. Let me tell you it works. I have seen bugs that come on the to the lawn and get in my peremeter and they start to die immediately. I have no ants in my house nor spiders not even the little ones that get in the corners. I spray at least once a year....or every spring and maybe late fall, while i lived in Iowa.
I cannot stand parasite, insects or anything of the like. With the Home Defense, they are no more! I will buy a spare!
I swear by this product. I used to spend close to $70 a month to have an exterminator come once a month or so to spray down the xeriscape (I live in the desert and true grass is frowned upon due to its excessive use of water). Huge bugs are possible here. I typically spray outside once a year around the perimeter of my home and am bug free for the year. Bugs may squeeze through cracks in the doorway but that's about as far as they get.
Answer: no
