Hey everyone! I've recently discovered some spider mites on my plants and since I'm quite busy with school, I'm looking for an effective way to eliminate them. I've heard that systemic granules like Bonide are illegal in Canada, which leaves me wondering what alternatives I might have. Are there any fellow Canadians out there who have dealt with this issue? I'd love to hear your suggestions!

Although I'm not Canadian, I've found success with a DIY spray using water, clove oil, garlic oil, and neem oil. First, I remove the mites manually with a microfiber cloth. Then I drench the plants with the spray, going after both sides of the leaves and the surrounding soil. It may require several applications, but it really helps keep the pests at bay. I also recommend trying Captain Jack's Dead Bug Brew if you want a commercial solution—just make sure to get the concentrate. Mixing some diatomaceous earth into the soil can help eliminate any eggs left behind too.
If you're looking for a low-effort option, predatory mites are a game-changer! You can order them online from Koppert Canada. They're effective at getting rid of spider mites without much work on your end. Plus, if you're in the GTA, I know someone in Markham who organizes group orders to save on shipping—just let me know if you're interested!
It's worth noting that using systemic granules like imidacloprid can actually worsen spider mite infestations, leading to faster breeding instead of getting rid of them. Instead, consider using insecticidal soap or a 1% horticultural oil. These options work by suffocating or dehydrating the pests effectively.
One effective method I've used is a mix of isopropyl alcohol and dish soap. Just combine three parts water with one part alcohol, and add a teaspoon of dish soap in a spray bottle. Spray your plants thoroughly, covering both sides of the leaves, and let it sit for a few minutes before rinsing it off in the sink or shower. After this treatment, you can follow up with neem oil or insecticidal soap if you want, but there's no need to rinse that off afterward.
