It was the location that was important. Like Mac, I piled on some vegetation in the middle of the float, too. Used under cover, they worked well during both fall and spring, but in the spring you have more rats traveling so production should be higher then. I do feel using them in places that afford protection for the muskrats from raptors work best.
Planetary Nebula are the outer layers of a star that are lost when the star changes from a red giant to a white dwarf. A star is a luminous globe of gas producing its own heat and light by nuclear reactions (nuclear fusion). They are born from nebulae and consist mostly of hydrogen and helium gas.
All stars begin as dust and tiny particles in a cloud of gas called nebulae. They develop into stars by passing through several stages over a period of millions of years. Once a star is born, it emits heat, light, x-rays, ultraviolet rays, gamma rays and other forms of radiation.
