Can Roaches Eat Through Plastic?

Cockroaches are gross and very hard to eliminate. Sometimes, we keep using natural home remedies to control the roach population, but a few remains there.

We learn to live with them and not bother a few roaming around. Overall, this approach is not appreciated, but if you are good with your remedies and just wanted to make sure that if you keep your food tightly packed in plastic bags, can a roach eat through them?

No, roaches can not eat through the plastic bags as there is nothing to guide them to bite it. Roaches need a valid smell to make them so.

Although roaches have strong jaws with sharp mandibles and giant roaches like American cockroaches can bite through thin plastic, they don’t pose enough IQ to make a path into it by systematically biting to cut out a hole. On the other hand, mice and rats are intelligent enough to carve out a path.

A sense of smell guides roaches. For example, if you keep some food in a thin plastic bag, the smell can seep through it after a few months, but cockroaches cannot get to them if the food is not directly touching the plastic surface.

However, large cockroaches like the American cockroach possess enough biting strength to bite through thin plastic but do not have enough IQ to pork a hole to get through it.

If the food inside the plastic bag is touching the plastic boundary like sugar stored in a plastic bag, large cockroaches can continuously bite to get a small amount of food.

Generally speaking, cockroaches won’t bite through plastic if there is enough food available other than the food inside plastic bags. A good quantity of food is usually available in our homes, like tiny food droppings, which are even hard for us to spot and enough to support roaches to survive.

However, if you have stored some food in a ziplock bag for a very long period (like more than a year), then the smell and taste of that food can seep through the plastic bag and may attract roaches if there isn’t enough food readily available.

Can You Suffocate Roaches in a Plastic Bag?

Just like every living being, cockroaches also need oxygen to survive. So all roaches, like other insects, breathe through their skin via special openings called spiracles.

Roaches commonly store oxygen in these openings and under their wings, making a cockroach survive underwater or without oxygen for up to 3 to 5 hours.

Similarly, if there is more oxygen trapped in the plastic bag with the roach inside, it can help a cockroach survive a few days before.

If the oxygen inside the plastic bag can help a cockroach survive for more than a week, it will die due to dehydration before it suffocates to death.

So, yes, we can suffocate cockroaches in a plastic bag if we take maximum air out of it. Nevertheless, it will die out of dehydration and lack of food if not suffocation. Freezing out a cockroach in a freezer will also instantly kill them.
