You need to ensure you are not keeping the plastic container open, especially if you have a high cockroach infestation.

Additionally, roaches can make entry into plastic container directly from the food. If you are keeping grains in a plastic container, then make sure to check the grains well before putting it inside the container.

A nymph can find its way inside grains and hide. You can overlook them as they are small. They can also poo, and die in the grains, which is disgusting, and you should not consume it.

This is why it is better to check the grains or any other edible products before keeping that inside a container.

Can Cockroaches Eat Through Ziplock Bags?

Because ziplock bags are thick, a roach cannot eat through. However, if the Ziplock bag is thin, they will eat through and gain entry.

Ziplock bags are an effective way of keeping edible products safe. However, make sure there is no opening. The problem with the ziplock bag is that the zip doesn’t work all the time.

It should zip to the end, but because of certain issues it doesn’t zip to the end and roaches can get in from there.

Once a roach gains entry through a tiny gap, it begins a feeding frenzy. If a zip lock bag is not zipping correctly, make sure to change it and put the food in a ziplock bag that is correctly working.

Avoid putting too much in one zip lock bag rather than purchasing more than one ziplock bag and put only adequate amount per bag.
