Works like a charm
This works awesomely. Everytime I spray this around my home on what starts to look like potential invasions, it gets rid of the problem so quickly, I dont even have the time to worry about it.

It actually works really well
I had seen ants migrate all the way to my coffee table to eat little bits of food and crumbs from around there. We are kinda messy and don't clean up every day so there was plenty for them to eat. When I was out on the deck I noticed the ants coming from the deck and going to the front door. In the front door there was a piece of candy they were swarming on that must have convinced them to check out the rest of the house. I sprayed them on the candy and they all stopped moving instantly. Then I went outside and sprayed the perimeter of the deck and wherever I saw the ant lines. I finished up by giving a very thick coating around the base of the front door where I knew they came in. Haven't seen an ant line since that day! They even disappeared from my coffee table without any spraying inside. Haven't seen any ants return and not seen any inside.My only issue is that when I was spraying so much a bit got on my hand that I was using for the trigger. The liquid on my hand did not cause any irritation and washed off easily. I'd suggest wearing gloves just in case.

A quick and effective solution to insects, especially ants
I have been using this for years. Every Spring the ants and other yucky insects start making their way into the house. Since I discovered Ortho Home Defense my irritation levels have been way lower. You simply give a good spray to the baseboards around your location, especially the ones on external walls, as well as any holes or entry points where you know insects come in, then let it dry. Don't wipe the floor there for a couple of days so it can sink in.In my experience, the insect activity immediately stops. I generally only spray once a season, but I may do spot touch-ups here and there. The product has low to no odor so it's not a nuisance. This is something you definitely want in your insect-fighting arsenal.

Amazed and thrilled
Due to the heat, we were getting a lot of spiders inside the house. The reviews on this spray were good so I decided to give it a try. I sprayed around thresholds, careful to follow directions. The smell is negligible, which was a delightful surprise. It also didn’t seem to bother my two cats, although we were careful not to spray directly around them, their food, toys, etc.It dried quickly. I was thrilled to find that it had an immediate and noticeable impact. We’re almost a month out now and I have not found one spider since spraying. We used to also deal intermittently with flies and have not seen them either! I have been recommending this spray to just about everyone.I hope it lasts the length it states it will, but even if it only last a few months I’d be happy. Application is quick and easy.

By far the best bug stopper
I have tried a few things and this is by far the best. I spray twice a year in all the spots I think bugs might try to sneak in and I don’t see any. Not even spiders in my garage they just stay clear of my house and must go next door. I’m telling you it’s wild and a must if you get any bugs around the house.

Not effective on ants.
I tried spraying it on ants that had invaded my cabinets. Unfortunately, the ants are still here.Why did you pick this product vs others?:I was able to order it and it was delivered the next day.Value for money:More expensive than sprays at Home Depot.
