Moles are considered cute furry animals but not when they have started creating underground tunnels in your yard. Usually, moles spent much of their time underground building a network of tunnels and looking for food such as white grubs and earthworms. This is unsettling most especially for gardeners whose beautiful flowers are dug out of their roots because of the moles activity.
A solution to this pesky problem is to use castor oil for mole control. Castor oil is usually extracted from the castor plant known scientifically as Ricinus communis. The plant’s extract actually contains a toxic protein which can affect moles and humans as well. One of the pronounced effect of castor oil is permanent nerve damage thereby making it effective as a pesticide.
Usually, castor oil is also used in making chemical and industrial products such as paints, lubricants, soaps, perfumes, dyes, and other pharmaceutical products. For this reason, preparations made with Castrol oil for mole control is considered effective. Some gardeners suggest mixing up a few tablespoons of castor oil with one gallon water containing a few drops of dishwashing liquid detergent.
Another procedure of using Castrol oil for mole control is mixing it first with a dishwashing detergent then slowly stirring it with a stick. The dishwashing detergent ensures that castor oil becomes soluble when mixed with water since oil and water do not combine well. After the solution has been stirred, a gallon of water can be added. After mixing the solution, it must be sprayed directly on the ground where mole activity is detected. This can simple be done going to the mounds of earth or patches of soil that moles dug up. Preferably, spraying Castrol oil for mole control must be done when the ground is quite soft so the solution can seep into the soil.
Application of the solution before the rain is also a good idea since the rain softens the ground thereby making the preparation more effective. Some prefer to spray when the grounds are dry (especially in summer): however, it must be considered that moles dig deeper under the surface. Dry soil takes time to absorb the Castrol oil for mole control thereby rendering the application less effective. In conclusion, using Castrol oil for mole control is a less costly and efficient method as compared to buying chemical formulations. It is therefore handy to have a bottle of Castrol oil at home.
