Do Rats Eat Bugs?

Written by: Gemmali Dizor

Yes, rats do eat bugs! Rats are omnivores, meaning they can consume both plants and animals alike. While they mainly feed on grains, fruits, and vegetables, rats have also been known to consume insects, small animals, and other rodents. In this article we’ll investigate the role of bugs in a rat’s diet; what types of bugs they eat; and their potential effects on behavioral traits as well as health outcomes.

Why Do Rats Eat Bugs?

Rats are opportunistic feeders, meaning they will consume whatever is available to them. This includes insects, which provide valuable sources of protein and other essential nutrients not found in their regular diet. Furthermore, rats have a natural affinity for hunting and scavenging, making insects an appealing food source.

Rats’ Favorite Bugs

Rats will eat a wide range of insects, such as cockroaches, crickets, beetles, ants, and termites. Some species such as the roof rat have been known to specialize in certain kinds of prey; for instance, they seem particularly fond of citrus fruits which attract ants; thus they could feed off these drawn-to-it insects.

What Effect Does Bug Blasting Have on Rat Behavior?

Bugs provide rats with essential nutrition, but their consumption can also have an effect on their behavior. For instance, hungry rats may become more active and aggressive which could result in increased hunting or scavenging behavior. Furthermore, insects present may cause competition among rats for food which could result in increased aggression and territoriality.

Impact of Bugs on Rat Health

Pests have a significant effect on rats’ health.

Bugs may provide rats with nutrition, but they also present health risks. Some insects, like cockroaches, carry diseases that can be transmitted to rats; additionally, bugs exposed to pesticides or other toxins may pass those chemicals onto rats when consumed.

Preventing Bugs in Rat Diets

Rat diets must contain an anti-microbial agent to avoid infestation of harmful insects.

To prevent rats from eating bugs, it’s essential to store food in sealed containers and clean up spills and crumbs promptly. Furthermore, regular pest control measures can help reduce the number of insects around your home, thus decreasing their availability to rats.


Rats often consume bugs as part of their omnivorous diet. Although insects provide valuable nutrition to rats, they can also have negative impacts on behavior and health. By taking steps to prevent bugs in rats’ diets, you can help ensure the well-being of your pet rats or limit wild rats from invading your home. If you are concerned about bugs affecting rat behavior or health, consulting a veterinarian or pest control expert for advice is always recommended.
