I was skeptical, but it works!
We have ants really bad in my neighborhood, plus I get a lot spiders in and around the house. I had been paying Orkin to come out every other month, but I would still end up with infestations. After a line of ants was going all the way around the ceiling in the kitchen, with swarms in the dishwasher and pantry, I asked friends and coworkers what they do, and multiple people mentioned Ortho Home Defense. I’ve only used it outside because I don’t like spraying anything inside, since I have pets, but since using it I have not had a single ant or spider in my house. Usually I’m dealing with ants at least once a week during the summer, and at least one spider every day during the fall and winter, but I’ve now gone months without a single pest in the house. I really thought that a professional pest control company would be the best approach, but it turns out that this stuff does a better job, for a lot cheaper. The wand that comes with this is nice, and has replaceable AA batteries, so I’ll probably be looking for a refill next time, rather than purchasing this exact product again, to cut down on waste.

Works great
We got tired of paying for a bug man that was expensive and didn’t really work that great.Researched Amazon for good products I could use myself. I came across this little gem of a product and now it’s all we use.The bottle sprays easy, product does not smell strong and keeps the bugs away for several months. We really only need to use about twice a year.If you’re on the fence, buy it!

It works!
It works! Spray a perimeter of your inside, doors and windows, do the same outside, and underneath and behind things. No more problem.

Orto Home defense Insect spray. 1 gal. w spray hose and wand.
Worked okay but i was expecting Greater results. I would need about 6 gals to do my basement from floor to rafters. Sprays great. Its smell not as potent as others not as bad as aerosol sprays, but if doing a large area, well ventilate and leave for few hours. Save container for your own d-i-y home-made remedies or after washing out well, great for watering flowers, garden, etc. Best advice, Get it on sale.

Good
It's a good product, but it's not as effective as it promises, which is why I only gave it three stars. It doesn't protect for as long as it says on the packaging, but it's good and cheap.
