HARRIS Spider Killer, Liquid Spray with Odorless and Non-Staining Formula (32oz)

Our floating rental unit attracts an amazing amount of spiders. The coated wire dock rails are spider heaven. I have been using this spider spray for years. I spray the entire deck and dock every 2 weeks during the summer season. I reapply after heavy rains but it really last for weeks without rain. They need to fix the sprayer head. It is junk. Not only does it stop spraying after a few pumps, it leaks if the bottle gets turned over. I found one head that works and have been moving it from bottle to bottle.

I've had a problem with spiders camping behind my car's side view mirrors for a while now. Every morning I would find a web, take it down, and then find another one made the next morning. I couldn't figure out how to get the spider to leave the space behind my mirror until I found this. I sprayed it into the crevice between the mirror and the frame and have not seen a web ever since. Either the spider died or it left. Thank you!When I moved into my studio I noticed spiders were getting in through the window cracks. I sprayed this along the window frame on the outside and inside and have not seen a spider inside my studio ever since. I plan to spray the cracks between the floors and walls but I haven't seen any spiders in here since spraying the windows and door frame. Great product!

You have to read the label or you’ll be disappointed. This isn’t intended nor does it kill on contact. This stuff is meant to be sprayed and let dry. Then and only then does it create a spider barrier. And it works well at what it’s intended to do. I sprayed probably 4-6 months ago and not until yesterday did i see a single spider. However at that point yesterday i realized the spray bottle doesn’t work anymore. On the spray setting it’s like it’s on the off setting. The trigger won’t budge much and when it does very little liquid comes out. Had to transfer it into a winded bottle.

the product worked. killed the first spider no problem. only downside is it isn't odorless - strange smell almost like mildew

We moved to a new house which is close to a ton of vegetation. With that comes spiders, a lot of them. I’ve tried many spider extermination products but none of them seem to kill spiders in contact. Well, let me tell you, this product worked! I spotted a brown widow spider and after a few sprays and squishing the damn thing, it’s dead. The spray will disorient the spider enough where it will stumble around, and a few more sprays will kill it. It works! The spray is unscented so that’s another bonus since we have kids around. So yes, highly recommended!

I keep my boat at a State Park Marina. The spiders are ridiculous and huge. I have counted an many as 30 new webs a day (this is a pontoon boat that I do not cover) with spider bodies larger than a nickel. After using this product only once, the spiders were all but gone the next day. I sprayed one more time on the 3rd day and have not seen any since. It has been 5 weeks. This product is the best I have used by far.

I've been using this. It was important that the description says it will not stain the area sprayed. I can not detect any smell left by the spray. I've just recently used this so I can't vouch for the 6 month effectiveness. Once sprayed I do not see any spiders. I also purchased one for my mother-in-law who regularly cleans and sprays for spiders. I'm tired of all the spider webs so I'm certainly hoping the product works as advertised. For right now, I see no returning spiders in sprayed areas.

This worked on the grand daddy long leg spiders that decided to gang up around two of my outside doors 😰, yay it killed them. Not as fast as Terri, but my state banned Terro. This new slide spray didn't do jack to another spider in a web on my patio, I don't know what it is... I directly sprayed it over and over, three days in a row. The spider moved its web to another location. Thus spray does kill all other bugs that accidentally come in contact with it, like beatles and June bugs. It also kills ants that I did spray on purpose. Ants are hard to eliminate for me, so that is a big plus.
