Absolutely Love this brand
I have been using this spray on my yard for about 2 years now. And I can say it is by far the best. It keeps the bugs at bay and away from the property. It acts as a great barrier and I can see the difference in the part of the property I have sprayed and what has not been sprayed. It last for about 2 months before I begin to see the bugs again so although the bottle says 3 months I would suggest spraying every 2 months.

If You Have Dogs: Helpful For Lawn Flea And Tick Control
Fleas and ticks are rampant in the San Francisco Bay Area. We’ve found Ortho Home Defense Lawn & Landscape to be a helpful tool in managing fleas and ticks on our dogs. It is easy to apply via spraying through attachment on your hose.Flea Note: Fleas are frustrating pests to get rid of, as they can live for a LONG time before hatching. So frustrating! You need to maintain an ongoing spray schedule to keep these pests under control in your lawns. One spray and done doesn’t work for fleas.I highly recommend this product.

Stealth Killer, powerful insects destroyer
It works great on my lawn. I hooked this insect spray into the garden hose, and circled spray it into the infested areas. The results were phenomenal, it neutralized the critters on contact. Buy it, try it, see the elimination at work!

Really seems to have tackled my mosquitto problem!
I have bushes and ivy galore growing behind my rental property. Mosquitoes were horrible! Followed the directions to spray the *UNDERSIDE* of the leaves of everything, and now – NO MOSQUITOES! I am super happy!!! I will update this post if/when the mosquitoes return, but – so far – I am more than happy with the results!Use this about a week or two before your next holiday/birthday party and don’t worry about these pesky critters!

UPDATED: Fleas are complicated. ORIG: Fleas living and prospering after 3 spaced spraying sessions
EDIT:I gave this product only 2 stars originally. But after doing research and following recommendation I managed to resolve my backyard flea problem with this product.The problem with fleas is that they sort of “hibernate” in hard shell cocoons. And its impossible to create a chemical product which is safe (non-toxic) and kills fleas in all stages: larvae, cocoon, adult. If you make such product, it would be highly toxic for humans too. With my overly simplistic approach I sprayed 3 times, but I just did nothing in between these spraying sessions. Teenage fleas hide in impenetrable cocoons and can stay there for months. They get out of their cocoons when there is a potential meal walking nearby. So I decided to combine the poison with luring the fleas out of their cocoons. I walked around the backyard, stomping and slightly jumping to cause surface vibration. Then I sprayed the yard. Now, after couple of such sessions the fleas are finally and completely gone.Summary. This poison is just a good tool. But you also need to know how to use it correctly.ORIGINAL:I have a tiny backyard closed with a fence. A few stray cats visited and left some guerrilla combatants in a form of fleas. I made sure that cats couldn’t trespass anymore and decided to use this product to kill fleas. I sprayed once. No result, same amount of fleas. Sprayed second time after a week. Less fleas, but still a lot. Waited another week and sprayed the third time. Three days past, there are much less fleas, but I still caught 3 fleas jumping on me. And even a single flee is too much. I must be zero. This product definitely doesn’t work. Remind you, there are no more cats.

AMAZING ANT CONTROL
I had paver ants under my paving stones in my back yard for the last 5 years, nothing worked. One application of this and they are gone. I had 50 ant hills on any given day, now, 3 months later, not one. AMAZING. This was the best pest purchase I have ever bought in my life. A pest control company suggested it when they could not come out to assist me with my ant issues. I thank them every day, I thank Ortho every day. AMAZING.

Gets rid of fleas in the yard
This stuff works great. The bottle didn’t leak like many others I’ve used. I wish that I bought a bigger bottle but this did the job for the small area in the backyard that had a lot of fleas which were being carried inside. The size of the bottle was perfect for half of my backyard. The spray isn’t too noisy and it’s easy to clean up after. The bottle isn’t made of a cheap flimsy plastic. It’s a durable plastic that you don’t have to worry about leaking out or puncturing the plastic
