There are a lot of water striders walking on my pool, so how can I get rid of it?

Does not bite, but has venom. Just pinch its abdomen with your hands and don't hurt it, its ciliated feet are easy to hurt, and it will be difficult to walk when placed in water. Water Strider.

It is a beneficial insect that can deal with a common aphid of floating aquatic plants.

If you have a pool of water in it, it means that the surface of the water should be large enough, otherwise it will not be able to hold it.

You stock some fish in the pond and use the water strider as bait.

It seems that the water in your house must be very clean, and there will be water pools, which are not poisonous.

If the pool is not large, it is recommended to change the water.

The hairs on his feet were afraid of oil, so he tried to push the kerosene on the water.

Water striders are aquatic hemiptera insects, Hemiptera, water striders. Scientific name: Aquarlus elongatus Habitat:

Inhabits still water or slow streams. Exterior features: slender body, very light; The forefoot is short and can be used to catch prey; The middle and hind feet are elongated and have fine hairs with an oily texture, which is waterproof.

The body color is dark brown and the body length is about 22mm.

The small aquatic insect water strider is known as the "skater in the pond" because it not only glides on the water, but also jumps and plays gracefully on the surface like an ice skater. Its brilliance is that it neither cuts through the water nor soaks its own legs. Water striders are not only harmless to humans, but can hunt and kill insects or become bait for fish.

You stock some small fish in the pond and the water strider is gone!!

You can add a special chlorine pill for swimming pools, and maintaining a certain concentration can kill algae and insects in the pool.

Use bleaching powder, but not too much, it can disinfect and kill insects. It is best to cover the top of the pool with a shade net to reduce light.

Buy a dosing machine and just add medicine.

As the mosquitoes stand on the surface, their feet draw a ripple on the water, and the tension of the surface causes them to float. And large animals, such as humans, cannot stand on the surface of the water. Because, if the object or animal is large, it cannot form water surface tension to support the weight.

"The smaller the contact surface of water with air, the more it resembles a trampoline, with a downward curved arc that can support the weight of an insect," David Hu said. If you calculate the size of your feet that you need to support your weight on the water, the result will probably be a thousand meters.

So, if you want to step into the water from the edge of the pool, you're sure to make a splash. We're so big that the tension on the surface of the water can't support our weight. If you're as small as an insect, you're good to go. ”

It's called a water fly, because the feet can float on water.

It is called water strider, which is a type of beneficial insect and a member of the balance of the entire water ecosystem.

That kind of insect is called water strider, which is a beneficial insect, and water strider not only destroys other pests but also makes bait for fish.

Of course, this so-called water drifting insect is a beneficial insect that can maintain the ecological balance in the water.

It's a pest, the kind of little insect that floats on the water, and the frog wants to eat it.

When I was a child, the "water floating" in the pool was supposed to be beneficial insects, and I used to play with it when I was a child.

They seem to me to be pests, because I have been afraid of them since I was a child.

I think it's a pest, but it doesn't matter if it's a pest.

Surface tension is the tension of the surface layer of a liquid acting along any boundary due to the imbalance of molecular gravitational forces. In general, the forces on the molecules at the interface are different from those within the phase body due to different environments. The net force of a water molecule inside the water by the forces of the surrounding water molecules is 0, but not a water molecule on the surface.

Because the attraction of the gas-phase molecules in the upper space to it is less than the attraction of the internal liquid-phase molecules, the resultant force of the molecule is not equal to zero, and the direction of its resultant force is perpendicular to the inside of the liquid, resulting in the surface of the liquid having a tendency to shrink automatically, and this contractile force is called surface tension.

It is supported by the surface tension of water.

It is not submerged in the water, it is not drained, and it is not buoyant by the water.

Reducing the output of the water heater can solve the problem.

Water pressure problem: a little fire sound and sparks, ignited and extinguished quickly, it is recommended that the user open the faucet to check whether the water pressure is too small, if the water pressure is too small, only the peak period of water consumption is staggered, or the water inlet filter screen is blocked and the water cannot flow normally, in this case, the water heater will not be burned, which only needs to clean the filter screen.

I think: 1. The pipe between the hot water pipe connected to the bathroom sink in your home and the mixing valve of the shower is blocked; 2. Your shower (mixing valve and above) or mixing valve is blocked, and the hot water pipeline is not working, resulting in no hot water at all, so if the water heater is not ignited, then there will definitely be no hot water; 3. It is also possible that although the pipeline is open, most of the inner diameter of the pipe is blocked by the raw material belt used for sealing when installing the pipeline or shower, so the water output is very small, resulting in a small pressure in the pipeline (the flow rate in the water heater is very small) and cannot be ignited, so there will definitely be no hot water.

It seems to be a problem with the shower, 1. See if the diameter of the water pipe used in the shower is too small, resulting in insufficient water pressure.

2. See if the water outlet holes of the shower head are not all open, and there are blocked holes.

3. The water outlet method of the shower head is not right.

You check it yourself first, but you can't do it and have to find a professional to take a look.

Remove the shower shower, and then try to see if it can be fired, if not, the shower aperture is too small, or blocked, change it or disassemble it with water and flush it in reverse; If it still doesn't work, remove the hose and try it! After removing the hose, turn on the faucet, if the water is very small, it is possible that the inner diameter of the pipe will become smaller and the resistance will be too great, and it will be troublesome to repair!

There are three possibilities.

1. Is the water pipe in your shower installed correctly?

2. The distance is too long or the water pressure itself is not enough, has your total water valve been opened?

3. If there is water in the shower, it means that the pipe is unblocked, and you can see if there is a battery.

The problem with the bath valve is more likely, followed by the fact that the water pipe may be blocked (if the water output is not as large as the sink) or the main inlet valve in the home is too small (the water pressure is not enough).

This may be the reason why Guangzhou is relatively long, Guangzhou is relatively thick.

It's the same in my house, just flip the switch again when you use it.

It should not be connected or there is something wrong with the water heater.

The first to recommend Xuanwu Lake! In the summer, you can see water striders on the water near the shore

In fact, there are many parks, as long as there are some small lakes and small pools

When summer comes, there will be something in the small pond.
