How to Stop Rats From Chewing Plastic


Rats have a reputation for being unsanitary and disease-ridden vermin, but they are just looking for food in most cases. Unfortunately, one of their favorite foods is plastic. This can be a problem because rats often chew through the insulation on wires, resulting in short circuits that cause fires or power surges.

Rats also gnaw on electric cables, creating sparks that could start a fire as well. Thus, these rodents are not only dangerous to humans but pose an enormous risk to our buildings and infrastructure due to their insatiable hunger for non-edible materials such as plastics and rubber products. In this article, I will discuss how to stop rats from chewing plastic. So let us get started.

How to Stop Rats From Chewing Plastic

Why Rats Love Chewing Plastic?

Rats love chewing on plastic because of the taste and smell. If you notice your rat licking the plastic water bottles, they may be trying to get a taste of the liquid inside rather than thirsty. Even if you remove all possible fluid sources from your rat’s cage, they will still try to chew through any plastic around them.

Rats are natural-born chewers, but their teeth grow continuously throughout their lives naturally, so some things can be done to discourage this behavior. Rats are also attracted to the smell of chewed-up plastic as well. So it seems like chewing on plastic is not only about having something tasty but also scents. You may have noticed your rating or licking where he has chewed on the plastic toys in its cage.

Most Common Places That Are Frequented By The Rodents:

1. Closed Buildings

Manufacturer stores, warehouses, etc. If there is no food available, rodents will end up chewing on your stored products like clothes, shoes, furniture, wires, and insulation materials (plastic) used in the heating/cooling systems for their taste buds.

2. Unsafe Places

Abandoned places, garbage piles, etc. Rats usually look for safe hiding spaces to breed and raise their young ones. Therefore, if you have any area in an abandoned building or under your house covered with garbage, this is the most suitable place for the rodents to hide because they feel secure.

3. Allergies

This is undoubtedly one of the main reasons why you (or your neighbor) may be facing rodent problems even if there are no empty buildings nearby. Rodents tend to multiply very fast; therefore, they can cause severe damage within a few months. It has been seen that people who are allergic to rat hair/droppings cannot bear their presence in their surroundings (even if it’s just one rat). Rats always keep on moving from one place to another; therefore, if you live in a neighborhood with many abandoned homes, then the chances of your neighbor’s house being at high risk are much higher.

A Detailed Stepwise Guide on How to Stop Rats From Chewing Plastic:

Although, it is believed that Rats are not fond of chewing plastic items. This myth has caused damage to many people because due to this misconception, they keep on waiting for their rodent problem to go away by itself. Trust me; you need to take immediate steps to prevent the rats from attacking your valuable goods (all types of plastics included).

Step 1 – Look For Signs Of Rat Presence:

If you have set up traps near your stored goods or under your house, then most probably you would have already caught a few rats. If you have not, then firstly look for signs of rodent presence. Rodents usually leave their droppings and urine behind whenever they visit any place.

If you can see lots of droplets/droppings near the stored products or if your neighbor tells you about rat problems in his home, then don’t delay contacting a professional pest controller as soon as possible.

Step 2 – Take The Necessary Preventive Measures:

If there is no current or past history of rodent attacks, but you suspect that there might be a risk of their attack, immediately take steps to prevent them from approaching your home/yard/factory/warehouse, etc. Rodents are susceptible; therefore, if they feel any threat to their life in your home, then they may come back very soon with lots of baby rats.

The most effective way to prevent them from entering is by installing rodent-repelling devices like electric rat zappers/traps etc.

Step 3 – Contact A Professional Pest Controller:

If you have already caught a few rats through traps or your neighbor tells you about rat problems, then don’t delay contacting a pest controller immediately because this type of problem can become severe within days rather than months.

Although it has been seen that the professionals often fail to deliver expected results in very little time; however, if you hire an expert available at your service for 24*7 hours of the day, then at least there are chances that he will get rid of the rodents before they become a threat to your life.

If you have noticed, rodents chew on any plastic item, be it an electric wire or insulation materials used for heating/cooling systems. This may cause a short circuit and fire outbreaks that can endanger your life and endanger lives around you.
