Never remove a trap with chemicals present; you risk burns to your skin. Call a professional but make certain you inform them of what chemical you used.
Originally Answered: Why is the Moon drifting away by 1 cm each year? Because of tidal forces between moon and Earth. As Earth and moon pull each other, bulges are created on the surface.
On average, the Moon is tidally locked to the Earthâs surface. But its actual orbit is elliptical, it moves closer and then more distant from the Earth. When the Moon is at its closest point, itâs rotation is slower than its orbital speed, so we see an additional 8 degrees on its eastern side.
