In the next few days, Zhang Zian temporarily handed over the pet shop and aquarium to the staff. In addition to the things he had to do, he spent the rest of his time running around the landfill and Zhonghua Road Primary School.
He first installed water pumps and small generators for the stray dogs, sent them daily food, and let the people at the waste collection station take away cans and empty drink bottles in exchange for the corresponding money. The stray dogs' enthusiasm for labor had greatly increased, and they were becoming more and more skilled. The number of cans and empty bottles they brought back every day was increasing, and they were getting more and more money.
Not only that, but there was also an unexpected side effect. In the past, the stray dogs had nothing to do all day, fighting and causing trouble, and mating when they had nothing to do. Now, under the temptation of chicken legs, the stray dogs had become model workers. In addition to the necessary rest, they ran to the landfill all day long.
In order to improve efficiency, they didn't have to carry only one bottle back and forth. Zhang Zian gave them a lot of wholesale sacks. Each dog was given a sack, filled with cans and empty bottles, and dragged back to the front of the artificial forest. Anyway, it was very light, and the stray dogs were medium to large dogs. There was no pressure to drag it, as long as they were careful of passing vehicles when crossing the road.
As for how to distinguish which sack belonged to which dog, it was too easy. They just had to pee on the sack. Every dog's urine smell was unique. At the very least, they would be able to tell it apart.
In the beginning, the money spent on buying dog food and chicken legs and selling empty bottles and cans could barely break even. Including the money spent on buying generators, there was even a small loss, but soon there was a surplus. Little White discussed with him that he would use the surplus money to buy some extra chicken legs for the breastfeeding female dogs to enjoy. They had to take care of the puppies, so they obviously couldn't participate in scavenging. They also had to maintain adequate nutrition.
This was a very reasonable request, and Zhang Zian had no reason to object.
The only problem was still the water source. Although there were pumps and generators, the power of small generators was limited. At most, they could only load three or four pumps at the same time. The stray dogs had to line up to drink water, which was very inefficient. Sometimes they were really thirsty, and there would be fights for the right to drink water.
It couldn't be helped. Zhang Zian had donated all the idle high-power water pumps in his shop, and high-power generators were expensive and heavy. They needed to be taken care of by professionals. It was impossible to buy additional water pumps and high-power generators. Although they could be used now, they would definitely be idle in the future, and it would be difficult to sell them second-hand.
Zhang Zian had decided to take advantage of the opportunity to solve the caterpillar problem for Zhonghua Road Primary School. He would also clean up the caterpillars in the artificial forest. Anyway, the money for protective clothing and pesticides was pooled together by the primary school teachers, so there was more than enough. It would be a waste not to use it. As for the caterpillars in the green space, the situation there was complicated and not very urgent, so it was temporarily at the back of the queue.
However, he also made it clear to the primary school teachers in advance that this was a temporary solution.
The effect of the pesticide could only last for about 15 days at most. When the residual pesticide on the branches, trunks, and leaves completely disappeared, the caterpillars would make a comeback. Although the caterpillars in the school had been temporarily eliminated, there were still a large number of caterpillars in the trees around the school. After the caterpillars turned into butterflies and moths, they would fly everywhere to lay eggs. A moth could lay at least 300 eggs. Even if only 1/3 of them hatched successfully, it was still a terrifying number.
Therefore, the only way to solve the problem was to carry out a city-wide extermination, and this … The subjective and objective conditions were not yet ripe.
The primary school teachers were very reasonable. It was good to have a 15-day buffer period. The future could be discussed later because the primary school students were about to take their final exams. After the exams, they would be on vacation. The same was true for the teachers. Perhaps it would not take 15 days for the higher-ups to issue a city-wide extermination of caterpillars.
Several male teachers and school workers who taught sports volunteered to help. The process of exterminating the caterpillars in the school was very smooth. It was smooth, but the process was really scary.
In the afternoon after the students were out of school, they wore protective clothing and gas masks, carried sprayers, and sprayed diluted cypermethrin solution on the trees in the school.
Cypermethrin was indeed a special insecticide that was highly toxic to bees and silkworms. After a white mist was sprayed, the caterpillars on the trees fell down like rain. They fell to the ground and landed on their protective clothing.
Every step they took, they stepped on the soft caterpillar corpses. They felt their corpses burst under their feet, and their body fluids and internal organs stained the soles of their shoes … It was really difficult for the average person to bear. A male teacher could not bear it after a few sprays. He ran to the side, took off his gas mask, and began to vomit.
Zhang Zian and several other male teachers endured the nausea and finally temporarily cleaned up the caterpillars in the school.
As for the caterpillar corpses, he could not help them. He could only trouble the cleaners the next day.
Next, he did the same thing and closed the business early in the afternoon. Then he took Wang Qian and Li Kun to clean up the caterpillars in the artificial forest.
Wang Qian and Li Kun were very ambitious. After dark, they could not see the caterpillars clearly. The degree of nausea was greatly reduced, but they still inevitably complained. It was not easy to get off work early, but they had to work hard again. They wore protective clothing and sweated like rain. It was so hot that they were about to get heatstroke. How could it be better to play games at home with the air conditioner?
Their complaints were easy to solve. The promise of barbecue and iced beer was settled. Summer was a good time to eat barbecue and drink beer.
Wang Qian and Li Kun also called Lu Yiyun and Jiang Feifei out to have fun together. For no reason, Zhang Zian lost a small amount of money …
The next morning, the water surface of the ditch was full of caterpillar corpses. They almost blocked the ditch, and even the pump could not work. It was not until noon that they were completely washed away by the running water.
The stray dogs, who had been working harder and harder, could finally drink water freely. This was very important in the hotter and hotter summer.
After inspecting the primary school and the artificial forest, he found that the effect of killing the insects was good. Zhang Zian, who had been running for several days, was tired and could finally take a breather.
However, his relief only lasted for less than a day.
During dinner in the evening, the familiar and sweet voice of the announcer came from the TV in front of Old Time Tea, but Zhang Zian suddenly lost his appetite.
"Due to a weak cold air moving south, it is expected that from tomorrow morning, the city will usher in a large-scale rainfall process from north to south. Citizens, please be prepared for the rain …"
The sky wanted to rain, and the mother wanted to get married. This was something that no one could stop.
