Why rats eat cockroaches

Rats prefer eating female roaches because they have milk that is rich in nutrients. This milk is sweet to rats, mice and other rodents because it contains sugar and fats. Additionally, it is rich in proteins and amino acids that are good for growth and development.

Rats will simply hunt the cockroaches by physically chasing, catching and eating them. They will also feed on the dead ones in case they come across them. The parts of a roach that rats and mice will leave behind after eating it include the antennae, legs and the wings.

They will also start eating a cockroach from the abdomen because it is a meaty area. In most cases, they will also leave the head and go for a new catch. When feeding on a female roach, they will eat almost everything because of the rich tasty milk that they keep in their body.

Adult roaches attract rats as compared to the young ones. Baby roaches are less meaty and rats will not really bother with them. Even if they eat them, they will end up spitting them out because they are not as tasty as the adult ones.

Surprisingly, roaches make a good meal for rats and mice especially if they are kept on a diet. Those that eat fresh vegetables, meat, and fruits are the best for rodents.

Do rats keep roaches away

Roaches are afraid of rats because they are a danger to them. However, you cannot depend on rats keep roaches away because they only eat them as an alternative. Only starved rats will eat roaches out of desperation. It is a serious hustle for rats to chase and catch cockroaches and this is a last option for them.

They will first look for their favourite meals and if they find none, that is when their survival instincts will kick in. Since the two are all nocturnal, they will go looking for food at night but the drama will start if there is no food.

A house that is infested with rats will also attract roaches because those 2 can coexist. Even though they will not live side by side because one can eat the other, cockroaches can eat rats’ poop. In most cases, a roach-infested house will also attract rats since there will be plenty of feeding alternatives.

It is therefore a myth to think that rats can keep roaches away since both will stay in a dirty house. They share the same habitats and both will always hide from humans and come out in the dark. Their droppings can also be similar in appearance unless you are very keen on details.  

Do rats eat roach bait?

Rats can feed on roach’s bait without any problem. Generally, cockroach baits consist of their favorite meals like starch and meat. Rats have the same taste and they will happily feast on any bait that contains both.

If a rat happens to eat a roach’s bait, it will also get poisoned. The amount of poison consumed is what will determine if they will die or not. Rats can tolerate more poison as compared to tiny bugs and cockroach bait will only kill them if they consume it in significant amounts.  

If the bait has just a little poison that is enough to kill the roaches, it will only make the rat sick for some time. Rats have a good immune system that will try to clear the toxic bait as much as possible. The bait will only kill them if it is loaded with toxic chemicals which is rare for a roach’s bait in most cases.

Rats and roaches share a direct feeding habit and this is why an infestation of one will invite the other sooner or later. Cockroaches will eat almost everything that rats can eat and those two can be found under one roof as long as they both have different hiding areas.

Just like rats and mice, roaches are also omnivorous meaning that they can feed on both vegetables and meat. Both can also eat dead decaying mater when they lack their favorite meals.

Both can also survive in drains and live on feces because rats cannot starve for long. However, this does not affect the quality and taste of the milk in female roaches that attract rats and mice.
