Effects. When a Worm is poisoned, its health slowly decreases every turn, usually 2 health points (5 in Worms 3D, and 10 in Worms 4: Mayhem) being taken away in-between turns. If a Worm is not cured, it will not die, but its health will eventually be reduced to only 1 health point, making it extremely vulnerable.
What will happen if a put salt in worm?
Sprinkling common salt on an earthworm leads to loss of water from the organism's cells through osmosis. The salt absorbs all the water volume from the earthworm.

How to reduce earthworms in lawn?
To reduce the earthworm food supply, and, therefore, reduce the earthworm population, gather and remove grass clippings from the lawn. This will also take away from the soil nutrients, informs the North Carolina Cooperative Extension, so it is important to add fertilizer to the lawn to account for the decrease in clippings, which are generally considered a form of fertilizer (an especially cheap form at that).

Why are earthworms important to agriculture?
Emphasis was placed on physical and chemical aspects of plant growth while biological aspects were neglected . We are now realizing how interactions between crops, climate, soil, and living organisms play important roles in sustaining our agriculture. Earthworms are among the most visible of soil organisms and have received considerable attention. They play a pivotal role in maintaining the productivity of our soils. This makes understanding these lowly animals and finding ways to make them thrive very important.
How does tillage affect earthworms?
In long-term clean-tilled fields, nightcrawlers are scarce. Tillage also stimulates drying the surface soil and wide day/night temperature fluctuations. This is another reason earthworms are less numerous in clean-tilled fields compared to no-tilled fields. Tillage brings earthworms to the surface where they are subject to predators such as birds. Total earthworm populations in long-term no-tilled fields are typically at least twice those of clean-tilled fields.
How do earthworms reproduce?
Earthworms are invertebrates composed of many segments (Fig. 1). They don't have bones and move by contracting and relaxing the body segments in sequence. They also have little bristlelike organs that help them cling to slippery surfaces. Most earthworms have both male and female organs. Typically, however, they still need a partner to reproduce. When earthworms mate, they lay side by side in reverse position. At that moment they exchange sperm. The sperm of the partner is stored in little chambers called spermathecal apertures. These are positioned in front of the egg-producing organs. After mating, the swollen external gland, called clitellum, produces egg cases called cocoons. A cocoon case slides slowly forward, picking up eggs and sperm as it moves over the head of the earthworm. From 3 to 1,000 cocoons can be produced per year, depending on species and environmental conditions. Typically, an earthworm will produce 20 to 30 cocoons per year, with each cocoon containing 1 to 10 eggs. Peak cocoon production is in the spring or early summer. The eggs in the cocoons hatch when conditions are right. Under ideal conditions, it may take from 1 to 5 months for the eggs to hatch. It may then take from 3 to 12 months before these worms are sexually mature. Worms typically live only a few months because of the many environmental threats they face. They have been observed to live for 10 years in a protected environment. In a favorable environment previously without earthworms, earthworm populations increased 80-fold in 4 years after introduction.
Why are earthworms important?
Earthworms are an important part of the soil ecosystem. They help improve soil structure and soil chemical and biological properties. They are especially important in no-till, helping to stimulate air and water movement in soil. Earthworms tend to thrive most without tillage, if sufficient crop residue is left on the soil surface. Crop rotations, cover crops, manure, fertilizer and lime applications all affect earthworm populations. Some pesticides, especially organophosphates and carbamates, are toxic to earthworms. Most herbicides do not pose a threat to earthworms.
How much dry matter do earthworms eat?
Typical earthworm populations can easily consume 2 tons of dry matter per acre per year, partly digesting and mixing it with soil. The importance of earthworms to mix surface residue with soil becomes very clear in soils that do not have any earthworms.
Why are earthworms tied up in a knot?
Earthworms in diapause are tied up in a knot in a little hole that is lined with a slimy substance to avoid moisture loss. Eggs in cocoons survive prolonged drought, allowing earthworm populations to survive drought periods. Because of dry conditions, earthworm populations in Pennsylvania are low in the summer.
How do earthworms help soil?
Once called the “intestines of the Earth” by Aristotle, earthworms are both indicators of soil health and help to improve the soil as they move through it. Earthworms tunnel deep within the soil, creating channels for air and water to pass through. As they tunnel, they bring up nutrients from below and carry organic matter from the surface, mixing it into the soil. Earthworms can#N#consume their own weight in organic matter each day, and Charles Darwin in his 39 years of studying earthworms, found that in a healthy environment they can create as much as 36,000 pounds of Nitrogen-rich castings per acre.
How much nitrogen do earthworms produce?

Re: insecticide that won't kill earthworms
Sevin makes a granular product with bifenthrin in it that you can get at HD or Lowe’s. I don’t think their concentrated product has the same formula, so check the label.
Re: insecticide that won't kill earthworms
Sevin is one of the most effective products I have used for killing earthworms. Bifenthrin is not harmful.
Re: insecticide that won't kill earthworms
So something like Amdro at Lowes would work well? If Bifenthrin is what one should look for, then the Talstar P I use for pest control (inside/exterior of house) would seem to work on my lawn as well. At that point it goes from something like Amdro, which is a granule, to Talstar P which is a spray.
