Review: Works Well and Easy to Apply - Good for Preventative Use - I’ve been using this as a refill for the Ortho Home Defense system, and it’s been working really well. It’s easy to use with the wand, and I like that you can apply it both indoors and around the perimeter of the house without a complicated setup. I haven’t had any issues with leakage. I mainly use it as a preventative treatment, and it does a good job keeping bugs from becoming an issue in the first place. It dries fairly quickly and doesn’t leave a strong smell, which is important when using it inside. The gallon size is a nice quantity and also lasts a while, so it’s a good value if you’re treating multiple areas. I think that this is a reliable option for home pest control that’s simple to apply, effective, and great for keeping bugs under control before they become a problem.
