What are the natural enemies of cockroaches and how powerful are they?

The origin of cockroaches can be said to be hundreds of millions of years ago, when no dinosaurs appeared on Earth. When dinosaurs ruled the Earth's continental ecosystems 100 million years ago, the ancestors of modern cockroaches evolved. Today, 65 million years after the extinction of the dinosaurs, cockroaches are still breeding on Earth and are quite active.

So how do cockroaches live that long? Are there predators? What animals eat cockroaches?

Let's take a closer look.

In the beginning, animals with strong reproductive ability had many natural predators. Cockroaches are small insects, and the common natural enemies of cockroaches are spiders, praying mantises, birds, scorpions, frogs, toads, waist bees, etc. Even the rats of one of the "Dead Seas" eat cockroaches.

It can be seen that there are indeed many natural enemies of cockroaches. However, these natural predators are praying mantises, birds, frogs, and toads, which are difficult to disperse indoors, so scorpions, waist bees, and poisons will shoot people, not to mention mice, and it is too late for people to destroy them, let alone kill cockroaches. So look at it this way, the natural enemies of cockroaches in the house are useless.

Cockroaches are afraid of plants that contain toxic substances, such as fresh peach leaves, old age, sheep's horns, phoenix willows, calendula, lily of the valley and other plants are all poisonous plants, cockroaches are more afraid of these plants, as long as they smell the smell of this plant, cockroaches will run away. In addition to this plant, cockroaches are also afraid of cucumbers and onions, and placing cucumbers and onions in places where cockroaches are often infested can also achieve the effect of repelling cockroaches. Cockroaches are afraid of high temperatures.

Generally, there will be no cockroaches when the temperature around the stove is relatively high. In summer, the indoor temperature reaches about 40, and the cockroaches die for about 4 hours. The high temperature accelerates the metabolism of the cockroach, so the oxygen demand increases, it takes a long time, and the cockroach withers and dies due to lack of water.

This is also the reason why cockroaches like to roost around refrigerators, freezers, and air conditioners in the hot summer.

Through the above content, I believe everyone should have a better understanding of what kind of animal or plant the natural enemy of cockroaches is. In fact, there are many kinds, such as small birds, which will also eat cockroaches directly, but the chance of encountering them is not very large, so the harm is not so great.

The natural enemies of cockroaches mainly include spiders, bees, toads, frogs, mice, and scorpions; Cockroaches are a very disgusting insect, it exists in all corners of the home, and has a very serious impact on people's lives, but its natural enemies basically cannot exist in the home, so cockroaches are still very harmful to people.

The natural enemies of cockroaches are spiders, cockroaches, frogs, scorpions, toads, these are the natural enemies of cockroaches, and cockroaches are most afraid of poisonous plants. It is quite powerful, it will make the cockroach die within 4 hours, and it will make the cockroach suffocate.

The natural predator of cockroaches is also almost the spider. This plant eats small animals and can be used to catch cockroaches.

The natural enemies of cockroaches are spiders. Cockroaches are commonly known as Xiaoqiang, they carry a lot of bacteria, a large number, and they reproduce quickly, and they are pervasive in the kitchen, bathroom, and sometimes even in the bedroom at home, and their vitality is not generally strong. Then the law of nature is that if there is one thing, there will be another thing, and spiders mostly feed on insects, other spiders, and myriapods, and are the natural enemies of cockroaches.

Some spiders also feed on small animals. Jumping spiders have good eyesight and can dive within 30 centimeters to catch their prey and pounce on them.

Predation process of cockroach predatorsCrab spiders wait for their prey on flowers of similar body color, and ground spiders burrow in the earth to build burrows lined with silk, and the entrance of the burrow has a trap that opens at night to prey on insects passing through the hole. This spider has short yellowish-gray hairs all over its body, a white horizontal band on its forehead, and likes to haunt slightly shady places, and this spider can catch up to dozens of cockroaches a day to eat, and cockroaches also like to live in dark and damp stone crevices.

Cockroach nemesis include spiders, scorpions, centipedes, ants, toads, lizards, geckos, cats, monkeys and mice.

Cockroaches prefer to choose warm, moist, abundant food and crevices to live, which are the 4 basic conditions they need to breed. These conditions are generally present in all buildings where people live and live.

To get rid of cockroaches, you must first ensure environmental hygiene, clean them in a timely manner, including toilets and sewers, and clean up garbage in a timely manner. Do not leave sanitary dead corners in the home, do not place food in the open air in the kitchen, do not leave stagnant water in the home, and plug the cracks and holes in time, so as to prevent cockroach breeding.

Prevention and control measures

1. Always keep hidden places clean. To find the source of the insects, you can suddenly turn on the lights at night when the cockroaches are active, observe where the cockroaches are, and where they are going, find their hiding places and then eliminate them.

2. For sheltered places, Keswei can be used in places where cockroaches often come and go.

3. Apply paper tendons and lime (500 grams of paper tendons plus 50 kg of lime, and then add water to mix) paint to all the gaps, and plug the gaps.

4. If there are too many cockroaches in the warehouse, workshop or indoors, and the harm is serious, it can be eliminated by sulfur or aluminum phosphide fumigation.
