Wet & Forget 803064 Miss Muffet's Revenge Indoor and Outdoor Spider Killer with Attached Sprayer, 64 Fluid Ounces, Ready to Use

I live in Michigan and the 1 quadrillion spiders here love to live and build webs around your windows, soffits, shutters, anyplace they can find a bug - which is everywhere. And then they drip bug juice all over your newly painted windowsills. Miss Muffet is extremely effective at killing and then REPELLING NEW ONES from moving in. Most of my problem areas are slightly protected from direct rain by overhangs above, so my comments are about that kind of application. I have found that this product is still effective after a year or even more - which is amazing to me. It does not effect paint or siding as far as I can tell. I use some caution when applying it with respect to personal protection. I always wear safety glasses, gloves, long sleeves and a n95 mask to avoid breathing the droplets that can blow back at you from gravity or an unfavorable wind. I did not do that robustly the first time and found that it was irritating. No problem with the gear and attention to the wind and using an "apply and retreat" approach.

We purchased an old farm house that was INFESTED with spiders. No joke, it was unreal how many spiders were in the house. The previous owners were very old and just stopped caring I guess. I am super anti chemical. After talking to a local Orkin man about having them spray for spiders, he informed me they are very hard to kill with chemicals and my best bet was to vacuum them up and their eggs. So I went on a vacuum spree and never stopped. I have spent the last five+ years vacuuming several times a week. They just kept coming back out of nooks and crannys, I could never kill them off. This year it was even worse. We had multuiple types and size, from small tiny barely visible ones to big fat ugly hairy guys. We had a poisonous one show up in my kids room and that was it. I did mad internet searches trying to find SOMETHING else that worked. I bought a decades supply of this stuff and went to work. I expected I would have to spray every inch of the joint before we could make a good dent. I started with one room in the basement so that I could gauge if it worked or not before I made the whole house full of chemicals and have it not work. I vaccumed up all the spiders and webs and sprayed around the whole room where the ceiling meets the wall, and along the baseboards, and the door frame and under the shelves. I came back 24 hours later and no spiders or webs. EUREKA! I kept coming back every day and NOTHING. Happy as a pig in mud, I started spraying the other rooms. A week later I had the whole basement done. I kid you not, each room would have over 100 spiders in them before vacuuming and spraying. I mean it when I say infestation. Since I sprayed each room, there has literally been ZERO live spiders seen in any of those rooms,. I have found several dead spiders laying on the floor, but its like they are literally SCARED of this stuff and totally avoid it. I am so very impressed with this product, I cant even tell you!!!! I purchased a case of it, and I plan on spraying again the moment I start seeing live spiders again. It has been over a month and NOTHING and this is our prime time for spiders coming in as its getting colder here now. This stuff kills AND repels them, truly works great! I did use gloves everytime I used this stuff, and when spraying overhead I wore work glasses. I will now use a face mask as well, as I noticed a super fine mist almost too small to see when I sprayed around the lights on the ceiling. I wouldnt have even seen the mist if it wasnt backlit by the ceilign lights. There is an odor to this stuff. Its not super strong, but the more you spray the stronger the odor. I just sprayed the rooms we occupy in segments to keep the smell to a minimum. The smell dissipats in a day or two, except the room where we keep our firewood. Thats our worst room for spiders and it opens to the outside, so I sprayed the ceiling beams until they were almost dripping wet. There is still a faint odor in that room, but barely noticeable to anyone but me. I am very chemical sensitive and get headaches easy from odors, and never got one from this stuff. I buy stuff on Amazon almost daily and rarely ever leave a review. I just wanted to give this product credit where its due, as I am truly amazed and so greatful that I found something to finally rid us of these darn spiders. I admire them outside only, in the house they are a total nightmare. Its so nice to see our home devoid of spider webs and not having to waste my time vacuuming celinings and walls every few days!!!! GREAT PRODUCT, DONT EVER STOP MAKING IT!!!

My porch was infested with big spiders! I used this product and it got rid of them all! It has been months since and not one spider in site. I did use a lot of spray initially because I sprayed the parameters of my home plus the outside but it worked very well. I will say that it will take some time for the spray to be effective. It does not have much of a smell to it but with any chemical I recommend wearing a mask. For the amount of spiders I had and to see none after months, I think its worth the money.

This spider killer has been absolutely fantastic for keeping spiders off our porch! We used to have constant spider webs and spiders everywhere - on the railings, corners, ceiling, and around the lights. It was becoming a real nuisance having to constantly sweep away webs, and my family was hesitant to spend time on the porch. After just one application of Miss Muffet's Revenge, the difference was remarkable. The spiders disappeared within days and have stayed away! The attached sprayer makes application incredibly easy - I was able to treat all the nooks and crannies where spiders like to hide. I sprayed around the perimeter, under the eaves, around door frames, and along the railings. The product creates a barrier that keeps spiders from coming back, which is exactly what we needed. It's been several weeks now and our porch is still spider-free. No more webs in the morning, no more spiders scurrying around at night. The peace of mind is wonderful, and we can finally enjoy our outdoor space again. The formula works for both indoor and outdoor use, which is versatile. Highly effective and long-lasting - this really works as advertised!

This spray worked so good I had to come back and write a review. I live in a basement with a bad spider infestation(college housing). I couldn’t sleep in my room they were in my clothes, bedding, every wall was covered in webs and it was multiplying by the day. I had my landlord come take care of this and to no one’s surprise his solution did nothing. I bought this and sprayed around hot spot areas, I made a line around the basement walls and entrance, I went all around the ceiling, I used the entire bottle. Immediate relief day by day there was less and less spiders. At first I saw a lot of dead spiders everywhere however it is apparent they die immediately apon touching sprayed areas because they would be dead along the places I sprayed. The infestation was primarily yellow sac spiders however I had all sorts of spiders that I found dead. Even better this stuff kills centipedes I didn’t even know I had a centipede problem until I’ve been finding giant dead ones along where I sprayed!!!! Now it has been about 2 months since I sprayed and I still haven’t noticed any spiders or pests I was so doubtful but this stuff saved me.

In the spring of 2021, we moved into our dream home out in the country, and immediately discovered it had a bad brown recluse infestation. (Yes they were actual BRs. I have 6 boys so I know more about spiders than I want to. I don’t confuse BRs with other spiders, and I have even looked at them with a magnifying glass to reveal/confirm their unique eye pattern.) The spiders were everywhere. Just strolling through the kitchen, sitting on the couch, and crawling onto us whenever they wanted to (which was often. Four of us have had one on our head at some point). If anyone felt something crawling on them, the person knew immediately without checking that it was a BR. I thought these “recluses” were supposed to like to stay away from people…These were trying to be part of the family. Each day we would see/kill at least 10 or 20, that were just casually hanging out in the living areas. Not including the ones the kids would tell us they saw in their rooms. It was a nightmare, and I would cry myself to sleep at night from fear and guilt that I was making my kids live in a house like this. My research seemed to suggest that professional help might not be as effective as we needed it to be. So I did what anyone in trouble would do—-I turned to Amazon. After reading reviews for many different products, I decided on this one and another brand. I tried this one first and never needed to try the other. I sprayed individual spiders and they died. Miss Muffets Revenge killed them on contact, but I wanted to know how good it was so I decided to conduct an experiment. Before spraying the whole house, I caught a bunch of the spiders. After seeing that they die when they touch the liquid, I put some in a large container with liquid that had dried. And they were dead the next time I checked. I even tried the experiment with liquid that had been dry for a long time. They died in every case. (They had each other for food, so they didn’t starve to death.) The spiders in the house also died. Rarely we’d see a small one (I could never find the egg sacs so I don’t know where the spiders hatch). The spray took care of at least 90% of the spiders, as far as we could see. Over the past four years, we have seen fewer BRs every year. I think I last sprayed like 2 yrs ago. I need to spray again, but I always forget because we just don’t even think about spiders anymore. (It LITERALLY IS “wet and forget.”)

This absolutely works! We moved into a new house that has a large screened in patio. The patio was absolutely infested with long-jawed orb weaver spiders. I initially sprayed the entire house and patio with Ortho Home Defense, which has been pretty effective for keeping roaches out of the house, but did nothing for the patio spiders. So I purchased this product based on the great reviews. I sprayed every nook and cranny of the patio and spiders were freaking out and falling from their webs everywhere, there were so many more spiders than I thought. This may be species or size dependent, but they did not die immediately, or even several minutes, after being sprayed. After about an hour I checked back and saw a ton of dead spiders, but there were some that were still alive but struggling. There was one outside my patio door that I kept an eye on after spraying it directly and it took probably 4 hours to finally die. So don't be discouraged if the spiders are still alive after a while. I also went out and sprayed the entire outside of the screened patio as well, as I noticed several spiders that were up under the roof on the outside of the screen. This morning I went out and didn't see a single spider that was still alive, but I saw tons of dead ones. I'm very impressed. I don't know how long the protection will last, but I can't imagine that I will get the full 12 months out of it, as it is outside in a hot an humid climate, I'm just happy to have a patio cleared of spiders for now. Other notes: I did not have issues with the sprayer, as some other reviewers noted. Mine worked just fine and was great because it sprayed quite far and allowed me to stand several feet back from the falling spiders. I did not notice any strong smell from the product, perhaps only a slight scent. This product did not stain the stucco exterior of my home. Update: I'm downgrading my rating as this product did not work for me except when sprayed directly on the spiders. I saturated my porch with this stuff and it killed everything that I sprayed, but the spiders came back immediately. This product did not kill or repel anything that wasn't sprayed directly. I need to go out every couple of days to spray more spiders. Overall, I find this product good for killing spiders that you can't reach or don't want to squish directly but it is not any good for keeping spiders from colonizing your porch.

This stuff is amazing. Sprays great and easy to use. Really keeps the bugs out of our house. Does not kill the bugs but worth the price and can be used inside the house without leaving stickiness.
