Here is information from books on animal husbandry:

Cockroaches are one of the most common food items for terrarium animals. Their advantages include extreme unpretentiousness in maintenance, rapid reproduction, lack of odor, and aggressiveness. There is essentially only one drawback - the ability to crawl on glass.
Cockroaches are a universal food for almost all lizards and amphibians, some turtles and snakes. But their mobility and ability to hide should be taken into account, so it is advisable to feed cockroaches by placing them in special feeders, partially removing the limbs, or offering them to the animal with tweezers.

Here's what the breeders say:

Today, the cockroach is one of the most popular food crops, this is facilitated by several qualities of this species such as: low cost, unpretentiousness and high fertility. For example, in 2 years, a colony of 40 cockroaches has turned into an army of thousands of destroyers of everything edible, and continues to grow.

IN Lately It has become popular to keep exotic animals and insects at home. You can make money by breeding some of them. This also applies to exotic cockroaches.

For comfortable stay and reproduction, rams need to maintain a temperature of about 25 C and air humidity (it is enough to spray the aquarium with water once every two days from a spray bottle).

For reproduction, it is enough to have two individuals (male and female). The cost of a pair of cockroaches usually does not exceed 300-500 rubles; young ones can be bought for 50 rubles. Cockroaches grow very quickly and comfortable conditions begin to reproduce. As a rule, offspring (10-20 cockroaches) appear within a couple of months after purchasing a pair of “newlyweds”.

The resulting offspring can be sold (to a pet store or through an advertisement), or you can do it more profitably and organize cockroach races as entertainment. Yes and original gift friends will always have it at hand.

How to organize cockroach races?

For competitions you need to have several (10 -15 individuals) trained “athletes” and a cockroach ring. A cockroach race looks like a large box with low sides made of transparent plastic or glass, the field is divided into running tracks, and the start and finish lines are marked. You can make it yourself, or you can order or buy it in a store.

Cockroaches participating in racing must be prepared in a special way and be on a special diet (usually cockroaches are not fed much 3-4 days before the competition).

How to implement a business idea?

You can offer your services at various corporate events, friendly parties, New Year, birthdays and even weddings. If you know the organizers and presenters of events, you can agree with them on cooperation and try your hand at it, you can also advertise in the media that a new service of an entertaining nature.

Each participant chooses a cockroach and cheers for it. You can come up with a funny nickname for the cockroach and encourage your athlete in every possible way. The presenter must develop a racing program, announce the start of the competition, announce the results of the races and reward the winners. Having good organizational skills and a sense of humor can turn competitions into an unforgettable holiday for its participants.

However, it is worth remembering that you cannot place money bets on such races; betting is prohibited by law in our country. But it is not forbidden to give a prize to the winner of the race.
