Trusted by thousands, it offers a reliable solution for managers and homeowners aiming to protect and enhance their outdoor spaces with minimal fuss. ## Description Bayer - Merit 0.5 Granular Systemic Insect Control - 30 Pound Bag Review: Works after a heavy rainfall - I just assumed that as this is a granular product that it was meant to be activated by rainfall and actually laid this out as it was drizzling outside. I only checked after it had turned into a downpour that it wasn't meant to be laid down that way so I was very worried that I did this all for nothing. Additionally, based on the reviews it seemed that I was putting this down way too late (September 20th). Well all I knew was I had very small grubs infesting my entire lawn and that we were expecting more warm weather (daytime weather between 70-80s, nights in the 60s). So I took my chances. Today September 26th I checked the soil. The grubs are all dead with just a few stragglers struggling to move. When exposed to air they just seem to stretch a bit like I disturbed their sleep and then won't burrow down like they normally did. This is very unlike they were before I laid down the Merit, so it is clearly working and working great. I'm very impressed with this product and am leaving this review in case it can help someone else. Thank you! Here we are now in May of 2019 and I just wanted to add a few details. The entire insect life was completely eradicated by this product. I would like to say that I still would have used this product because I live at a NJ home that didn't receive any lawn care for probably 30 years. Lifting just one paver on my lawn would expose about 30 grubs, so I literally felt that I was at ground zero for the Japanese beetle problem. I had skunks, an army of birds, opposums, racoons, you name it digging up my lawn at all hours of the day and night. Now however I am trying to make the soil healthy and know this is unnatural and not good, not to have a single earthworm etc. left over. I can't say with absolute certainty that it was the Merit, it could be that the Tenacity weed killer I've used also contributed to this but be aware that this is a very strong product. Once you get your problem under control or you only have a minor problem, I would choose a product that is less harmful to all the other insects and bees as those bugs are very important to your soil health and if you are growing flowers and/or have a garden. Review: GRUB BE GONE..........πŸ’¨ - The Bayer Merit granular is easy to spread by hand or with a seeder without making a huge mess which was a plus. These grubs were destroying our yard along with the birds and other animals that munched on them. Bare spots in the grass, erroded soil, and mushy ground were some of the problems that arose. We spread the insecticide right before a steady rain, which seemed to be the way to go after reading others reviews. In the weeks to come we noticed less and less destruction. We have been able to patch the bald areas of grass and plan to apply bayer merit again as directed. Great product. ## Features - Imidacloprid 0.5% - Merit is for use in and around Turfgrasses, Trees, Shrubs, Evergreens, Flowers, Foliage Plants, Ground Covers. - Applications of MERIT 0.5 G Insecticide cannot exceed a total of 80 lb (0.4 lb of active ingredient) per acre per year. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0053S5ATU | | Best Sellers Rank | #34,316 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #168 in Insect & Pest Repellent Spray Concentrates | | Brand | Bayer | | Brand Name | Bayer | | Customer Reviews | 4.6 out of 5 stars 621 Reviews | | Included Components | 1 bag | | Item Form | Granules | | Item Weight | 30.1 Pounds | | Manufacturer | Backed by Bayer | | Model Number | 09090530 | | Part Number | 9090530 | | Specification Met | EPA | | Target Species | Insects | | UPC | 785740198124 | ## Product Details - **Brand:** Bayer - **Item Form:** Granules - **Item Weight:** 30.1 Pounds - **Specification Met:** EPA - **Target Species:** Insects ## Images ![Bayer - Merit 0.5 Granular Systemic Insect Control - 30 Pound Bag - Image 1](https://m.media-amazon.com/images/I/61Ogwxrp9qL.jpg) ![Bayer - Merit 0.5 Granular Systemic Insect Control - 30 Pound Bag - Image 2](https://m.media-amazon.com/images/I/61kiuWam62L.jpg) ## Questions & Answers **Q: When using this product for control of grubs, does it also kill the earthworms?** A: no not in my lawn....I used it for Grubs and Mole Crickets, works great! **Q: Should I use this product before seeding or after seeding or it doesn't matter?** A: Since it is a systemic insecticide it shouldn't effect seed germination at all. I would apply it at the same time you put seed down and water it in well. I don't know where you live but this product should provide protection for around three months. **Q: Does it kill ticks?** A: No,it doesn’t as the label clearly states. **Q: How do I spread this for lace bugs on azaleas? Some are small bushes. Others are 8 feet across of bushes growing close together.** A: Since this is a systemic insect control you would have to loosen the dirt beneath the bushes and then apply around the base of the plants. It will take some time for the plant to take this up into its system and kill the bugs. It is a bit late in the year for this treatment to be totally effective, you should be starting in the spring with this. Might I suggest a spray that will take them down now https://www.amazon.com/Bonide-Chemical-426-Garden-Insect/dp/B000OWC16U?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=ATVPDKIKX0DER ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works after a heavy rainfall *by R***I on September 26, 2018* I just assumed that as this is a granular product that it was meant to be activated by rainfall and actually laid this out as it was drizzling outside.

These grubs were destroying our yard along with the birds and other animals that munched on them. Bare spots in the grass, erroded soil, and mushy ground were some of the problems that arose.

We have been able to patch the bald areas of grass and plan to apply bayer merit again as directed. Great product. ### ⭐⭐⭐⭐⭐ It does work. Don't blame the product if it doesn't. *by C***W on August 3, 2023* I have been using Merit for a few years after one year of learning that my brown easy-to-pull-up grass was a result of grubs. Merit fixed that. Then moving into a new home the lawn was green, but I started feeling soft areas in the lawn that were not there when I cut the grass a few times. There were also raised trails and a large patch of soft grass. I learned that I had moles! Moles eat grubs. Merit kills grubs (and other insects you may or may not want). Grubs and moles are now gone! I read reviews claiming Merit didn't work for them. I call that a likely user error. YOU MUST apply Merit at the appropriate time. If you don't, it will not work, or not work as well as it can. It's up to the user to do their homework because every environment/location is different. Watch the weather so you don't end up with it washed away because of too much rainfall. Most importantly, timing matters. You can't get rid of grubs if you apply Merit, or any other product at the wrong time. Don't expect results that you think should work if YOU apply it at the wrong time. Again, don't blame the product for that. ## Frequently Bought Together - Bayer - Merit 0.5 Granular Systemic Insect Control - 30 Pound Bag - Heritage G 30lb Ready-to-use Granular Fungicide - Scotts DiseaseEx Lawn Fungicide, Controls and Prevents Disease Up to 4 Weeks, Treats Up to 5,000 sq. ft., 10 lbs. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/7496235-bayer-merit-0-5-granular-systemic-insect-control-30-pound](https://www.desertcart.pe/products/7496235-bayer-merit-0-5-granular-systemic-insect-control-30-pound) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-05-07*
