Finding a pantry moth larva in your Saturday morning pancake batter is really disgusting. It totally ruins the weekend. If you have ever opened a bag of flour and seen something moving around you know how bad that feeling is. Pantry moth larvae are a problem. Finding pantry moth larvae in your food is the worst.
The problem is usually the packaging. I mean the paper bags that flour and sugar come in. These bags are not good for storing things for a time. They let air in and out and they get damp easily. This makes it easy for little bugs, like weevils or ants, to get inside the flour and sugar bags. The flour and sugar bags do not protect the flour and sugar from these pests at all.
To stop the infestation cycle you do not just need a jar. You need a container with a kind of seal that is made to keep air out. This seal is made from silicone. It is engineered to compress. Here are the best airtight systems to protect your baking staples, like flour and sugar. You want to keep these things fresh. The infestation cycle will not bother you if you use a good airtight container with a compression-engineered silicone seal.
The Science of the Seal: What Actually Stops Bugs?
Some containers that have lids are not completely airtight. For example, a regular cookie jar that you screw the top on and off or a nice ceramic container to hold things; these often do not have a seal to keep the air out.
To really keep weevils out a container needs a silicone gasket.
- This gasket gets bigger when the lid is closed.
- It makes a kind of vacuum seal that stops smells from getting out. Weevils are attracted to smells.
- This seal also keeps eggs or bugs from getting inside the container. The container needs this silicone gasket to be weevil-proof.
The Top Contender: Rubbermaid Brilliance Pantry
If you want a safe place to store your flour then this thing is perfect for keeping your flour safe. This is the way to protect your flour.
- The Seal: Uses these strong latches on the side. When you close The Seal these latches make a snapping sound. This sound means The Seal is shut tight and the thick rubber piece inside The Seal is being squeezed.
- The Material: The material that this thing is made of is really cool. It is made from Tritan plastic. This Tritan plastic looks like glass. The great thing about Tritan plastic is that it is shatterproof. So you do not have to worry about the Tritan plastic breaking.
- Why this thing wins: It has the best seal you can find when you buy things for your home. If you drop it the lid will stay on. The shape is also really good because it is rectangular so it stacks up nicely. It uses all the space on your shelf. This means you can fit more of these things on your shelf because they stack perfectly.
The Baker’s Favorite: Progressive ProKeeper+
Rubbermaid is really good at keeping things sealed. On the other hand, Progressive is much easier for bakers to use. This is because Progressive thought about what bakers need when they made their product. So when it comes to being easy to use, Progressive is the choice for bakers, not Rubbermaid.
- The Feature: This thing has a bar inside that helps you get the right amount. You can put your measuring cup in the bin. Use the bar to scrape off the extra. No more shaking the cup around or using a knife to get it just right. The Feature is really helpful because it has this built-in leveler bar that makes it easy to measure things.
- The Seal: It is really useful because it has a lid that opens and closes. This lid has a silicone edge and a strong stainless steel lock. The Seal is good at keeping things fresh like sugar, which stays soft for a very long time, even months.
- The Capacity: The capacity of this thing is really good. The 4-quart model is the right size to hold a standard 5lb bag of flour. You will have some room in the 4-quart model. This is very useful for people who need to store a 5lb bag of flour in the 4-quart model.
The “Zero-Plastic” Option: Le Parfait Super Jars
For those avoiding plastic entirely, go with the classic French canning jar.
- The Mechanism: A heavy wire bail clamp system.
- The Reliability: These jars are really good at keeping things. They are made to hold liquids that are under a lot of pressure like when you are canning. So it is very easy for them to keep out a moth. The orange rubber ring is like a wall that nothing can get through. The orange rubber ring works together to keep everything out. The orange rubber ring is the key to making sure these jars are secure.
- The Downside: The bad thing about these is that they are really heavy and round which means they take up a lot of space on the shelf. Also, when glass gets covered in flour dust it can be very slippery to hold onto.
The “Freezer First” Rule
The best container for flour that keeps air out still cannot get rid of bugs that are already in the flour bag you bought from the store. These bugs are like eggs that are already inside the flour bag when you buy it. The flour container can keep the flour fresh, but it cannot kill the eggs that are already in the flour.
The Expert Protocol: Whenever you buy a new bag of flour, place the entire paper bag in the freezer for 48 hours before decanting it into your airtight container. The cold kills any dormant eggs, and your new container ensures nothing new gets in.
