I just barely barely squirted tiny tiny bit of it and oh my goodness it works great so when I get done with a bunch of throwing away and reorganizing of my stuff I moved to a smaller place and I have about half my stuff I need to throw away when I get all done doing that and I'm down to much smaller mouth stuff then I'm just going to paint the whole inside of this place and get it vacuum cleaner and get ready to suck them up but it does definitely work well and I like that I don't like those spiders and stuff and look critters and it's an apartment I live in now so got to spray everything cuz all the neighbors stuff will come under the baseboards where they don't put caulking and just run over to your house and run back to their house so we're going to nip that in the bud or spray and kill everything let everything know that wants to come in here and live and it ain't going to work but it's very good product and the price is nice.

I Use Home Defense Regularly

I use the Ortho Home Defense regularly inside and outside. I don't have roaches and I use the standard Ortho Home Defense that kills most all insects. I decided to buy this particular product because the price is good and I do want to make sure there is no ants entering come Spring.

Works for me

Spray around outside on foundation once a year and no bugs. Use to have ants coming in but couldn’t find entry point so go all around. No more bugs. Works to keep spiders and webs away by spraying at entry doors. In spring when wasps are on porch, I spray along top and they go elsewhere to make nest. Always use to have wasp nest on porch before starting spraying. Works great for all my needs.
