Looking at Manager Liang leaving with a frown, Zhao Yuqing asked Zhang Fan: "Is it very serious?"

"I don't know yet, as long as there is no rat infestation, it is not serious, and it can be controlled. Zhang Fan said.

In fact, I am also a little apprehensive in my heart, because of the net bottle, the environment of Zhangjiazhai is getting better and better, more and more suitable for the settlement of various animals and plants, and it is not impossible to attract mice.

Don't make it into a rat's nest, that would be a great sin.

The plague of rats and locusts, as well as the plague of sparrows, is almost on the same level. Once they reach a certain level, they will be quite destructive.

Rats are an animal that will hardly become extinct, and many harsh environments on the earth can survive, which is a headache. Even if you live in a big city, you can feel the troubles of rats.

The harm of rats to industry and construction is also very serious, and accidents caused by short circuits caused by rats biting power wires are not uncommon, and the harm is serious.

In fact, rats in the countryside are a little better, and they are less likely to carry the virus.

In big cities, rats and mosquitoes are always carriers of the virus. The rat infestation once became the focus of people's attention.

Rodent infestation is the vector of many diseases, and can transmit more than 30 diseases such as plague, epidemic hemorrhagic fever, and leptospirosis.

At present, there are only a few ways to exterminate rodents: environmental rodent extermination, physical rodent extermination, chemical rodent extermination, biological rodent extermination and ecological rodent extermination.

Physical rodent extermination, chemical rodent extermination and biological rodent extermination are easier to understand.

What is environmental rodent extermination?

Rats need water, food, and sheltered habitat to survive and reproduce. Therefore, creating an environment that is not suitable for their survival can greatly reduce the rodent population in a place and make it easy to consolidate the results of rodent extermination.

Therefore, we must first do a good job of environmental hygiene, remove weeds around the house, random piles of items, often clean indoor and outdoor hygiene, all kinds of utensils and sundries are tidy, clothes, wardrobes, books, shoes and hats should be checked frequently, so as not to make rodents nest.

Cutting off the food of rats is the most direct way, rat food not only includes human food, but also includes feed, garbage, food industry scraps, feces, etc., these things should be stored in a covered and no gap container, so that rats can not get food and passively eat the poison bait, in order to achieve the purpose of eliminating rats.

In fact, just like humans, when an environment is not suitable for the breeding of species, it will naturally relocate.

As for ecological rodent extermination, it is similar to environmental rodent extermination.

Zhang Fan took Zhao Yuqing to the other side of the valley, but before he could get there, he asked the female workers working there to complain and told the rats that they had bitten off more than a dozen watermelon vines.

Zhang Fan was depressed, he was really afraid of something.

Fortunately, he built a greenhouse, otherwise the watermelon field would have become a paradise for mice. There is the protection of the greenhouse, which can somewhat prevent some rats from entering.

"I'll take a look. Zhang Fan said.

Zhang Fan attaches great importance to those black-skinned watermelons, and naturally he can't let the rats run rampant. If you want to say who has the greatest impact on the rat plague, it is undoubtedly his family.

After drilling into the greenhouse, carefully observing the watermelon vines that were bitten off, Zhang Fan frowned.

The most hated thing by the peasants is the rat, whether it eats it or not, whether it fills its stomach or not, it still destroys your things. And, very greedy, a rat will often store several kilograms of grain and hide it underground for the winter.

If there is a large group of rats, they may take away the rice in the whole village.

"Did you find the hole they got into?" Zhang Fan asked.

A woman shook her head: "I've searched all the way, there are no signs of bites in the greenhouse, it is possible that she slipped in when she opened the door of the greenhouse." ”

Suddenly, there was movement in the distance, and animals were chasing.

Zhang Fan and the others instantly cast their eyes over, only to see the melon vines in the distance shaking. And the fox beside Zhang Fan also sniffed hard, suddenly showed a fierce appearance, and rushed out at once.

"It's supposed to be a mouse, and the fox seems to catch mice. ”

Zhao Yuqing blinked: "That seems to be a big mouse!"

Judging from the shaking of the melon vines, it can be guessed that it is a small animal chasing after it.

Zhang Fan and the others also walked over: "Close the door." ”

After getting closer, Zhang Fan was surprised to find that it was not a mouse that confronted the fox, but a cat the size of a tiger calf, with fierce eyes and a whining warning sound in his mouth.

The fox bared its teeth and looked unhappy with the creatures that had intruded into its territory.

Zhang Fan was extremely speechless to the fox, you don't catch mice yourself, and you don't let others catch them, what's the matter?

"What a big bobcat, what breed?" Zhao Yuqing's eyes lit up, it was the first time she saw such a big cat, and her coat color was very beautiful.

Zhang Fan shook his head and said, "It's probably not a bobcat, it's not that big." ”

Bobcat Zhang Fan is not unseen, the male cat raised in the village, if it is not castrated, will return to its wildness after a certain period of time, run away from home, and run to the mountain to be the cat king, that is, the bobcat in everyone's mouth.

The bobcat that has returned to the wild will also become larger, but it is not so exaggerated.

The one in front of him, dressed in a slightly red golden retriever, with a very beautiful pattern, and a body length of seventy or eighty centimeters, was definitely not a cat, and he suspected that it was a leopard.

However, Zhang Fan couldn't help but what kind of variety this was.

At this time, there was a big mouse under the paws of the big cat, almost the size of a rabbit, no wonder it could attract the big cat and run in to catch it.

Zhang Fan took out his mobile phone, called Kong Lao, and asked them to come and see if it was a leopard.

At the same time, protecting Zhao Yuqing and the others while retreating, don't annoy this ferocious creature, as for the fox, he didn't pay attention to it, anyway, the fox who drank so much spiritual water, if he couldn't beat the big cat, he would have nothing to say, right?

It's just that Zhang Fan is already a little dissatisfied with the fox, and you actually let the rats run in to have a party on your own territory, it's unreasonable!

Kong Lao asked Zhang Fan to take a photo, and when he heard the word leopard, he became interested and said that he would rush over immediately.

Zhang Fan secretly took two photos of the big cat, and was opening the door, preparing to take Zhao Yuqing and them out, after all, it was a bit dangerous to stay here.

But as soon as the door of the greenhouse was opened, the big cat ran out at a very fast speed, and the fox was a little confused.

"!" Zhang Fan burst into foul language.

And Kong Lao, who was rushing over, looked at the picture and was pleasantly surprised, if he was not mistaken, it should be the golden cat, a precious jungle cat, which is already an endangered species, and many zoos can't find them, but they can also be found in Zhangjiazhai.

However, after coming, he was told by Zhang Fan that he had run away.

Kong Lao led a group of people to stare: Ran away?
