How Long Can Roaches Live In A Sealed Bag?

When you think of roaches, you probably think of dirty, disease-ridden pests that are best kept out of your home. But did you know cockroaches can survive being sealed in a bag without air for extended periods?


Roaches can survive for 3-5 days inside a sealed bag. This is because they can hold their breath for up to 40 minutes.

Cockroaches can also withstand being submerged underwater for up to 30 minutes.

So, sealing these pests in a bag is not the most effective method for getting rid of them.

This article will outline how to prevent roaches from getting into your sealed bags and, if they do, how to get rid of them. So, stay tuned!

How Do Roaches Survive in a Vacuum Sealed Bag?

Vacuum Sealed Bag

It may seem like an airtight seal would be the surest way to kill a cockroach, but these pests are quite resilient. If you put a cockroach in a vacuum-sealed bag, it would likely survive for some time. However, eventually, the lack of oxygen would kill it.

Cockroaches can survive in such extreme conditions because they can hold their breath for up to 40 minutes. They do this by slowing their metabolism and taking oxygen through tiny holes in their exoskeleton. This ability to go without oxygen for long periods allows cockroaches to survive in a vacuum-sealed bag.

All in all, it all has to do with their unique physiology and respiratory system. Cockroaches have an open circulatory system, meaning their blood (or hemolymph) is not confined to vessels like veins and arteries. Instead, it flows freely throughout their body cavity and into their appendages.

As a result, roaches exchange gases (oxygen and carbon dioxide) directly with their environment through diffusion. This means cockroaches don’t need to breathe through their mouths as we do. They can absorb oxygen through their bodies from the air around them.

How Do Roaches Get Into Sealed Bags?

Sealed Edible Bags

Roaches are attracted to food and moisture, so they are often found in kitchens and other areas where food is stored. If a roach finds its way into a sealed bag of food, it will most likely be because the bag was not properly sealed or because there was a hole or opening.

Even the smallest hole can provide enough space for a cockroach to squeeze through and contaminate your food. Once inside the bag, the roach will feed on the food and lay its eggs. The eggs will hatch, and the cycle will repeat itself.

Other Ways

  • Another way roaches can get into sealed bags is by coming in contact with the bag before it’s sealed. If a cockroach crawls on the outside of a bag, it can leave feces, saliva, or eggs, contaminating the food inside.
  • Cockroaches can get into sealed bags by hitching a ride on someone’s clothes. If you’ve ever been in an infested area, you may have unknowingly brought roaches into your home on your clothing.

How To Keep Roaches Out of Sealed Bags?

Here is how you can prevent roaches from getting into your bags and infesting your home:

Seal All Food in Airtight Containers

Airtight Food Containers

Roaches are attracted to food, so it’s important to keep all of your food sealed up tight. This includes keeping pantry items like cereal and pasta in airtight containers and ensuring that any open bags of chips or snacks are tightly rolled and stored away.

Keep Your Counters Clean

Clean Food Counters

Roaches are also attracted to crumbs and other bits of food left on countertops or floors. So, keeping your home’s kitchen (and other rooms) clean and free of any potential food sources is important.

This means wiping counters after cooking or eating, sweeping up crumbs, and regularly taking out the trash.

Eliminate Moisture

Plumbing Leakage Fixing

Roaches are drawn to moisture, so it’s important to keep your home as dry as possible. This means fixing any leaks in your plumbing, using a dehumidifier in damp areas like basements or bathrooms, and making sure that any wet clothing is hung up to dry rather than left in a pile on the floor.

Seal Up Entry Points

Cracks Around Windows

Sealing up any potential entry points roaches could use to get into your home is important. This includes cracks and crevices around doors and windows, gaps around pipes and cables, and any other potential openings.

You can use caulk or weatherstripping to seal up these areas, which will help keep roaches out.

How To Get Rid of Roaches in Sealed Bags?

Sealed Food Bags

If you have roaches in sealed bags, there are a few things you can do to get rid of them.

  • One of the best ways is to throw away the bag. If the bag is infested with roaches, it will likely die off – especially if it’s a sealed bag without food or water.
  • However, if you’re uncomfortable throwing away Infested bags, you can try freezer treatment. Simply place the infested bag in the freezer for a few days, then dispose of it.
  • You can put some poison in the bag that will kill the roaches. This is a good option if you have many roaches in the bag.
  • You can also wash the bag with soap and water. This will kill any roaches in the bag and prevent them from getting into it again.
  • You can get a new bag if you don’t want to deal with the roaches. This is the best option if you only have a few roaches getting into the bag.


To prevent roaches from getting into your food, store all food in airtight containers and seal any holes or openings in bags before storing them. You should also regularly inspect your pantry and cabinets for signs of roaches or other pests.

If you find roaches in your home, you may need to call a professional exterminator. Exterminators can provide more powerful pesticides and baits that can kill roaches quickly and effectively.

Frequently Asked Questions

Can One Roach Start an Infestation?

The answer to this question depends on a few factors. If the roach is female and pregnant, then it is certainly possible for her to start an infestation. A single roach can lay up to 50 eggs at a time, so if just a few of those eggs survive and hatch, you could quickly have dozens of roaches running around your home.

Will Vacuum Seal Bags Kill Cockroaches?

Yes, vacuum seal bags can kill cockroaches. The sealed environment will suffocate the roach and die in 40 minutes. However, it is important to ensure the bag is completely sealed before killing a cockroach. If there are any holes in the bag, the cockroach will be able to escape and survive.
