HARRISSpider Killer, Liquid Spray with Odorless and Non-Staining Formula (32oz, 2-Pack)

Love this stuff. I spray it every month or 2 (depending on time of year) to keep spider out of my house. I think I can count on one hand how many I've seen alive inside and it's usually when it's time to spray again. I'll see dead ones while cleaning pretty consistently.

I have used this product on my pontoon boat for the past 8 years. It is a pontoon boat that is exposed to weather for the whole 7-month season in Upstate NY and I apply 2 times a year (even with the rain) it is long lasting

No more spiders for now. Spray once a week in webby areas. Haven't gotten spider bite in bed in weeks😁

If you have windows with webs behind the curtains , webs inside the screens, webs in the corners, ANYWHERE! You must buy this. Once a moth I spray a brush on a long handle and hit all the corners inside and out. Take a cloth, gloves on your hands, and dampen the cloth. Wipe screens, and anywhere else. Spray under furniture…there is no smell and does not harm fabric. I would not be without it.

I bought this product because it had excellent reviews however I sprayed all around my home and I continue to see the spiders alive and well (lol)! The smell is not bad but if you spray too much it can be very overbearing.

The smell is honestly terrible, I don’t know how or why they would say this is odorless. I think I’d rather have a typical chemical smell compared to this. The product also stained our walls and discolored the painted walls.

Where I live, certain times a year the spiders try really hard to take over every window, nook, cieling corner, hollow, arch, door handle, light fixture, and doorway. 90% of then are harnless, but we have blsck and brown widows that I just wont toleratr. I started spraying this and notice an immediate drop in spider population, and after about 6 months the spiders start to show up again but not near as many. This year I'll try doing a spring spray, then an early fall spray. Might eliminate the problem once and for all.

Harris spider killer works great! I have a yard full of western black widows. I am someone who truly believes that all spiders have an important place in each of our little ecosystems even these dangerous widows. But due likely to my xeriscaping efforts I have dozens of them in a small area. I have tried a lot of other spray and natural remedies with unimpressive results. I sprayed the spiders that I saw, with Harris spider killer, and they crawled about 10-18 inches before curling up dead. Then this morning found several more that I hadn’t directly sprayed dead as well. These spiders are pretty tough but Harris spider killer worked fast a more complete then I expected. If I had a complaint it would be that pump sprayers suck, in general, but that is a very small price to pay.
