Review: I said goodbye Indian Meal Moths with Doktor Doom!!aa - I am in the process of trying to clean up a NASTY and large Indian Meal Moth invasion. After clearing and cleaning every "base camp", we thought we were in the clear, but not so much. Turns out these things live FOREVER and they can be hard to kill, unless you want to chase them with a broom and leave brown streaks all over your walls, YUK! I started looking online, and wanted a natural solution. There are A LOT of pyrethrum products, but I finally settled on Doktor Doom Spider Mite Knockout. I knew it was more for garden pests than indoor issues, but I had to try something, ANYTHING! I received it 3 days ago and as soon as I opened it I went hunting. Let me tell you, if you have Indian Meal Moth issues, you will LOVE this stuff. It takes them out of the air, off walls, just about anywhere. Also, anywhere that I have sprayed it, as far as I can tell, no moths or any other bugs will land. The only con about this product is that it does not come with a holster. Other than that, it's all pros. Definitely recommended. Thanks for killing my bugs!!!! Here's to many more buggies biting it!! Cheers!

My only experience was a Large Schefflera. I sprayed the plant outside, and much to my disappointment about a day later the plant started to shrivle and eventually died. **Q: doesvthis product kill mies inside?** A: This product kills mites inside and outside. **Q: I want to kill (or let die) any possible spider mite eggs in a previously-infected but currently empty grow tent. Suggestions?** A: I would first thoroughly clean the inside of the tent with warm soapy water in an effort to remove any debris that could offer safe haven for mites or their eggs. Then you could use this product to spray the tent corners and other hard to reach areas to further eliminate any lingering infestation. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I said goodbye Indian Meal Moths with Doktor Doom!!aa *by D***S on August 6, 2012* I am in the process of trying to clean up a NASTY and large Indian Meal Moth invasion.

I had spider mites on a Jasmine plant and they spread to a baby maple tree that I'm trying desperately to grow before our full grown maple tree dies (it's had some bad luck over the years). Well, I sprayed both plants outside and followed the directions on the can. 2 days later there was absolutely no movement on either plants. And after another 3 or 4 days I was surprised that my jasmine plant (which has many small leaves and stems) had been sprayed thoroughly enough to kill the whole infestation in one go. My maple tree, however, had a resurgence of mites after 5 days. They had begun to spin webs around all of the top leaves and had a few threads between the bottom few. So I waited another 2 days to spray it again because as directed you're supposed to wait 7 days between sprays. The day after I sprayed the second time the mites were all dead, but, to my horror, the leaves began to all turn brown starting at the edges. I assume that the mites may have done most of the damage, but I also suspect that the chemical spray may have had a hand. My maple tree is still alive with a few brand new leaves coming in at the top. It's also mite-free. But if you have a delicate plant (young, small, and/or with fragile leaves) and this plant has a spider-mite infestation, use this product very lightly and as early as you can before the major damage is done. My suspicions about it's plant-killing potential is why I gave it a 4/5 star. ## Frequently Bought Together - Doktor Doom Spider Mite Knockout, 16-Ounce - Doktor Doom DDTRF5-1/2OZ 5-1/2-Ounce Total Release Fogger - Doktor Doom DDTRF3OZ 3-Ounce Total Release Fogger, Mini, 3 oz, Red --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/4899082-doktor-doom-spider-mite-knockout-16-ounce](https://www.desertcart.be/products/4899082-doktor-doom-spider-mite-knockout-16-ounce) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-26*
