These 'Shark Tank' household hacks are game-changing — get our favorites, from $7

Don't let mosquitoes ruin your summer — this fan-favorite bug bite remedy is here to spare you from itchiness. It sucks out the venom, saliva and anything else wreaking havoc on your skin without relying on chemicals or creams, and it's completely reusable. Just place the opening over the bite you're trying to target, slowly lift the handle to gently apply suction, hold it for 10-20 seconds and press down to release. This is as low as it's been in years, so scoop up a couple to keep in all of your warm-weather bags just in case. 

Made from 100% organic Turkish cotton, this beach essential is soft, lightweight and free of harmful chemicals — great for the shore and beyond. It repels sand, dries quickly and doubles as a yoga mat, picnic blanket or cozy throw. Best of all, 10% of profits go toward marine life conservation, so you can feel good while you lounge. 

"Had always heard the hype about these towels but decided to try for myself," revealed one intrepid reviewer. "Even with the high price tag, I confidently can say I think they are worth the price. Be careful not to dry them in the dryer; they will shrink significantly. The towels dry really quickly out in the open/outside and do repel sand from the beach so well. Used on vacation to California and also used as a blanket/scarf to wrap up while walking along the beach in the evening."

This little monkey "hat" goes over a BPA-free silicone cap that blocks bananas from emitting ethylene gas that helps them ripen. The inventor of these adorable food savers brought the idea to Shark Tank after he bought bananas that turned brown overnight. (Psst: They come in a "bunch" of fun designs.) 

"Amazing! Kept my bananas good for a whole six days! They never got overripe!" exclaimed a five-star reviewer. "I usually buy them super green, and by the second day, they are just right. Now I can buy them barely green and they are perfect the whole time!" 

We all love the convenience of a drive-through, but not so much the console clean-up afterward. These holders take the mess out of using ketchup, honey mustard and/or barbecue sauce on your fries or rings while you're on the go. Since they come in multipacks, you and a friend can dip to your hearts' content.  

Fast-food lovers adore this clever find. Said one, "Works great! Very helpful while traveling and eating on the run. After I bought this, I bought another set for my husband's car, and my two daughters have bought them for their cars." 

These skinny spatulas get into those hard-to-reach corners in bottles and jars that regular spoons and knives can't reach. We wouldn't want a single speck of peanut butter left behind, would we? They're 6 and 12 inches long to fit containers of multiple sizes. 

"No more wasted lotion! Absolutely amazing idea and works on so many things!" wrote a frugal fan. "I used to cut the top of my lotion bottle off to get the last inch or so that wouldn't pump out, and it would dry out and get lumpy. This is the simplest but smartest little tool!" 

If you find yourself always pushing your glasses into place, so much so that it's become your signature move, then this is the thing for you. Apply the wax liberally to your eyeglass arms and nose, and you'll suddenly see the world a whole lot differently.  

"Nerdwax really works!" gushed a seer turned believer. "My glasses were creating a red spot on my nose and making it sore. I went to the eyeglass store, and they said to go see a dermatologist. I did, and they pointed a finger back at the glasses. So I searched the net and decided to try this. Inexpensive but effective, I'm so pleased."

Got unwanted facial hair? These little strips couldn't be easier to use: All you do is rub them in your hands to heat up the wax, then press 'em on your lip and let 'er rip!   

"I found these magic wax strips and I have never looked back," raved a stache-free shopper. "Easy to use. They get 99% of my hair lip removed as easy as 1-2-3. It is smooth and not even red. I don't even use the aloe cream that is included because it is not necessary. I can't be happier with this product." 

How'd you like to clean your clothes with minimal soap? That's right; no more sudsy overkill, no more soapy clothes that need an extra rinse cycle, no more weird chemical smell that pretends to be lavender or eucalyptus or the unspecified scent of a meadow. This mineral pellet-filled egg, which contains just a teeny bit of detergent, cleans up to 70 loads of dirty clothes — if you do laundry about four times per week, you'll only need to replace pellets every four months or so.   

"I've been using the Eco Egg for the past few months and honestly, it's the best clean laundry detergent I have ever tried, and I've tried a lot of them," wrote a smitten shopper. "It's so convenient to just dump that cute little thing into the machine and not have to deal with ordering, carrying around and measuring detergent. I use it for all types of loads, and it works fantastically. I use it alone (no softeners/conditioners) or with some vinegar. Can't say I notice the scent on the actual laundry, so I'll opt for the unscented one next time, which is the other great thing — one pack of detergent refills should last me for more than a year. So far, so good!"

You know how frustrating it is when your bed sheets get all tangled in the dryer and come out damp? Well, this genius invention solves that dilemma. You'll get two Wad-Free gizmos, which attach to the corners of fitted and flat sheets to keep everything else from getting trapped inside. 

"Where have these been all my life?" pondered this linen launderer. "Like most people, my sheets end up in a wadded mess, both coming out of the washer and the dryer. I don't know how these work, but they are a miracle. Now I'm not running my sheets through two or more dryer cycles to get them dry, and they're not in a ball when they come out." 

This gadget is more or less a chain attached to a plastic flower that hangs from your shower drain into the pipe. It grabs hair that goes down the drain to prevent big clogs from forming. The best part: It's disposable. 

"These do exactly what they are designed to do," said one dis-tressed enthusiast. "I drop one in the drain and remove it a month later with what looks like a ratty squirrel tail attached. Replacing it takes seconds. Saves me a fortune in liquid drain cleaner."

One of the most popular Shark Tank products and an Amazon No. 1 bestseller, this ingenious invention is made of squishy neoprene and fills the gap between your car seat and the center console to stop things like phones, fries and coins from falling through.    

"The last time I dropped my credit card between the seats, I was in the drive-through at my pharmacy," reported one of tens of thousands of delighted customers. "I had to get out of the car and crawl onto the floorboard of the back seat, much to the laughter of my friends. I said, 'Never again' and ordered this product. These really work. I dropped something the other week and felt that dreaded feeling … but it was right by my side. What a great invention for a simple problem."

Made of silicone, these food bags are reusable pouches designed to replace single-use zip-top bags. Yes, they're a bit pricier than the disposable ones, but think of how much money they'll save you over time. 

"I never thought I would have an opinion on a baggie, but here we are," wrote a rave reviewer. "I have five of these, one for each day of the week. I make my husband a sandwich to take for lunch every day, and these baggies have made a world of difference. They hold up extremely well, they’re easy to wash and dry and they keep his sandwiches extremely fresh!" 

Meet the "good cop" and "bad cop" of washing-up time. Arguably the most mainstream Shark Tank star, this sponge hardens in cold water, making it tough enough to scrub away grime from pans and other caked-on surfaces. Run it under warm water, and it'll be gentle enough for porcelain and glass — and it won't scratch them, either. All it takes is a few seconds under the sink.  

"The cleaning influencers are right; these sponges are fantastic," reported a happy buyer. "Not only are they cute, but they are so effective. If you use cold water, the abrasive side stays stiff, which is perfect for washing things that are really stuck onto pots/pans. However, they are not so rough that I am worried about scraping the finish on whatever I am cleaning. It's the perfect Goldilocks in-between. If you use hot water, the sponge becomes more malleable and you can better get into the nooks and crannies." 

These look like dryer sheets, but they contain laundry soap that's activated in the wash. Now you can ditch those giant jugs of detergent and give your arms a break. 

"I will never lug a heavy plastic detergent bottle again!" shared an erstwhile prince of Tide. "This product is wonderful. It not only cleans exceptionally well, but also dissolves instantly in water and leaves clothes smelling fresh with a light, clean scent." 

Made for 10-inch skillets or pans, this silicone accessory catches grease spatter to prevent oily messes on the cooktop and counter. Unlike splatter screens, this guard grabs grease while still giving you access to the food you are cooking. 

"Saved my marriage!" revealed this fan. "My husband started on the carnivore diet and has been cooking bacon and a lot of other meats on our stove. This caused a greasy mess daily on my stove/counter area. I was incredibly tired of cleaning up the grease splatters only to have him make another steak just a few hours later. Our screened grease cover seemed to not work and made it impossible to stir/flip things. But this grease shield works amazingly well. Husband laughed at it until he tried it! So easy to use. Easy to clean and can roll up smaller for storage. Best of all, my stove now stays clean!" 

Choose from six fun colors or this classic black — they also come in packs of two!

This special kitty litter is made with pH-sensitive crystals to help you monitor your cat's health. The litter changes color to show you things like hydration levels and changes in urinary tract health. It also has odor control and clumps for easy cleaning. 

"We bought this product and it works great," shared a pet parent. "I have an older cat and she was meowing a lot lately (kitty dementia), but no other signs of anything. The litter indicated a problem, so we took her to the vet, and it was confirmed." 

If you're all about whipping up vats of sauces, soups and stews, this tray can help you make sense of what you're storing in the freezer. They're made with food-grade silicone and take care of the portioning for you — the niches come in ½-cup and 1-cup sizes. Just ladle your soup into the container, throw the lid on and put it in the freezer. When you're ready for a bowl of soup, pop a portion out like an ice cube and heat it up. 

"Absolutely obsessed with these," shared a frozen food fanatic. "We've been doing a lot of meal prep with soupy foods, and these have been incredible. Freeze it into blocks, then you can fit eight frozen blocks perfectly into a gallon Ziploc bag to save space. So far, we've used these for butternut squash soup, lentil curry, Indian butter chicken and chicken broth. So nice having them in 1-cup bricks to easily defrost. They feel super high quality. I'm recommending these to everyone I know."

If your skills in the wrapping department aren't at Martha Stewart-level, this slicer is here to help with all manner of birthday, bridal and baby shower presents. This can make the process go a lot quicker — and save paper!

"Great little gadget," praised a gratified gifter. "This wrap cutter works so well. I cannot cut a straight line to save my life, but now with this gadget, it is easy. This is a great value for a two-pack! It slides on the paper like butter. Highly recommend."
