    Garden pest prevention


    To help get rid of pests in your garden there are a few prevention methods you can try to reduce the appeal of your backyard.

    Maintain soil health

    Ensuring that all vegetation is watered properly and using organic fertilizers will help keep them, and the soil strong and healthy, helping them to withstand pest damage. Removing weak and damaged plants can also assist in your efforts to maintain healthy soil.

    Clear garden of debris

    Removing old tree stumps and fallen branches can make your garden less appealing to garden pests. Removing old and rotting fruit and vegetables will limit potential food sources as well as limiting the spread of fungal diseases.


    Using barriers made from copper and certain fabrics can be good alternatives to pesticides in some circumstances. Different barriers can be used for different garden pests, by helping to protect plants from pest damage.

    Repair damages

    Repairing any damages to your shed and greenhouse will help keep pests away from stored items such as seeds as well as plants and flowers.

    Regularly inspecting these areas of your garden will help ensure a quick, reactive response to garden pest infestation. Using expanding foam, wire mesh and a door bristle will help keep pests out of your shed or greenhouse.


    Store compost in a secure location and ensure it is sealed in a container with a tight lid to help prevent garden pests. Compost can often provide pests with a great place for harborage. Remove easy access to compost to keep certain garden pests away.

    Remove standing water

    Standing water in buckets, trays and flower pots provide biting insects such as mosquitoes with the perfect nesting environment. Water in birdbaths and pet water bowls should also be changed regularly. Removing this element from your garden can help with your prevention efforts.

    Make sure ponds have a sufficient filtering system, or an agitator, and regularly inspect for mosquito eggs to help control their number.

    Garbage cans

    Ensuring garbage cans aren’t overflowing with garbage as well as secured with a tight lid will help eliminate potential food sources for many garden pests. This will help make your garden less appealing, as well as reducing the possibility of obtaining a pest problem in your home.

    With these tips and suggestions, it's quite likely that you will be able to enjoy your garden pest-free this summer. If, however, for any reason you find yourself with a pest issue that you cannot fix, be sure to call in the local pest control experts at Western Exterminator.
