BioLogic Ecomask Beneficial Nematodes, 5 Million Steinernema carpocapsae (Sc) Nematodes for Natural Flea Control Plus Easy to Use Hose End Sprayer (Value Pack)

I got this product with high hopes. Fleas have been increasing steadily over past few years. In past I have had professional exterminators with little success. I sprayed lawn with commercially available products, treating home, pet areas and pets at same time. I have used IGR in home and yard. All products seem to decrease flea population for limited time only. Irregardless of what label says, with or without IGR, I rarely get a few weeks of decreased fleas. It is becoming cost prohibitive. I'm worried about the environment as my and pets health with this increase in pesticides. I found out about nematodes doing a search for a better, safer and healthier way to get rid of fleas. I'm giving this 5 stars because the package arrived with cold packs still cold. This with temps near 100 here in South Central Texas. From my reading, I know that these may not work due to the excessive heat this time of year. I plan on giving it a try anyway. FYI; FOR THOSE LIKE ME WHO KNOW NOTHING ABOUT APPLYING NEMATODES. Apply evening. Aerate soil if possible. A pitchfork works fine. (1) Use amount of water needed for application method and substitute food coloring for nematode amount. Apply solution to area. This will show time needed for application, how much/little your technique is applying thus avoiding missed areas. (2) Nematode mixture must be cool. Depending upon outside temps and device, you may want a cold pack in or around it. (3) Moist ground is a must. Apply after a rain or water well before and as indicated after to help nematodes get established. Nematodes hunt their food. Moist soil will helps them. (4) SHAKE, AGITATE MIXTURE FREQUENTLY during application. Every site stated nematodes mix sinks. Without good shaking, depending upon application method, the question is when device will clog not if. I have high hopes for this method. EDITED 8/23/2017: I have a dramatic decrease in fleas. I'm impressed by the quick response that I had. I do want to say that last month I applied pesticide and IGR to yard twice about 2 weeks apart. I had only a brief decline in fleas. Home and pets were treated at same time of those applications. I applied these beneficial nematodes just over 2 weeks after that. I got them as a last resort for fleas. Due to no rain, I watered ground twice (12 hours apart) before application of nematodes. I watered ground again 3 days later. I also applied nematodes heavier in dog's outside area and all areas that stay shady. I also treated house and pets at same time. Wish I had found out about beneficial nematodes a long time ago! Edited 12Feb2018. It has been about 6 months since applying nematodes. I can't say when but I noted before cold weather set in that my dog was no longer bringing in fleas from outside. I noticed that we were going from weekly flea baths for dogs and indoor cats to every other week to monthly. The progress was slow but definite! I plan on repurchasing and applying this again.

This is the third time I bought BioLogic Ecomask as I am extremely allergic to fleas. Whenever I am outside the fleas jump on me and bite me. Fleas can transmit many diseases including lyme disease. My indoor cat was infested with fleas in the past and I realized that I was the one bringing the fleas inside my house. After doing extensive research I kept reading about beneficial nematodes and found this product and decided I had nothing to lose by trying it. 1 year ago (May 2019) I bought it and followed the instructions completely. Yes, if you don't follow the "exact" instructions it will not work. You must refrigerate the product once it arrives, you must water your property beforehand, aerate the soil/lawn. Spray the nematodes after the sun goes down and be sure to water your property again after spraying. The Nematodes go into the earth and start spreading killing flea larvae. I re-applied this product in August of 2019 NOT because I was bit by any fleas but because I wanted to make sure that I would not. I did not get bitten once last summer nor do I bring any fleas inside my house. I just used this product last night because that's how well it works. If you're on a budget this product is still cheaper then using chemicals, going to your vet, and getting treated for any infections that fleas can transmit (such as lyme disease). It is a natural as well as effective way to stop the flea problem before they get inside and start an infestation. Highly recommend this product and will continue to keep using it!

First of all, the packaging was wonderful. I received my item quickly, on a hot day, and opening it immediately, I found the cooling packs packed with it still nice and cold. The directions were easy to understand, and I mixed and used the product that very evening. I had watered the yard before spraying, and watered slightly afterwards, then again for the next 3 days because it's warm and sunny right now, and I wanted my 50 million little guests to have a shot at surviving. This year's fleas are mutant super-survivors who have still managed to harass my dogs in spite of my using other flea control products conscientiously, including the monthly chewables plus the topical, from the vet, not the supermarket. I simply could not in good conscience add one more chemical to the mix, so this was my Hail Mary attempt, and I'm very happy. I believe it's working. I haven't actually trapped and counted fleas, but the big and most important proof that this product is working is that my dogs have stopped biting and scratching themselves silly! I plan to order more in a few weeks and give my yard another treatment, just to catch anything that might have escaped the first time. PS: I think the fly population has been decimated, as well.

I’m pretty sure this worked for my fungus gnat infestation. I used sticky traps for a while but wasn’t getting them all, treated all of my plants about a month ago and I haven’t seen any new gnats! The sprayer bottle didn’t work however, just buy the nematodes. The instructions are kind of confusing but just read them a few times.

We had a terrible time the other year with fleas in our yard and even though we only had a house cat, we ended up with fleas in the house because they were getting on our socks and shoes when we were outside and getting a ride indoors. My husband researched options because we don't like to use chemicals if we can avoid it and found these. We treated the area around our deck and lower yard and it got tons better in terms of visible fleas. We used it the following year as a preventative. Don't know if they were the only reason, because of course there are other factors outside each year, but in the year that they were bad, we did find that this made a significant difference in a short time with no major changes to anything else outside.

Do not order the sprayer! Got the front yard sprayed with no problems, then it quit working when I got to the back yard, and it quit working, took it apart cleaned it out, even tried thinning down mixture by adding more water, so I just went around and poured it out by hand which was a big waste. As for the fleas, probably would have worked better earlier in the summer when it wasnt so hot. We kept the yard watered every day, and about a week or two later, the fleas were not as bad. We still pick fleas off of the dog, but not as many. I also sprayed the inside of the house with I.G. Regulator, which helped also.

I'm not sure what we are doing wrong, but we have applied these nematodes to our back yard twice so far this spring, and have not seen a decrease in the flea population. The first time, I may have waited a few days too long to apply them, as we had heavy rains for over a week after I received them. A few weeks later, we decided to try them again, and applied them the day they were received, double-checked to ensure we were following the instructions, kept the lawn in our enclosed back yard watered daily, and while it seemed to help a little, once the weather gets sunny and warm, my pets come in the house covered with fleas again. We are vacuuming twice daily, using both diatomaceous earth and Wondercide inside the house, and I flea comb all four pets twice a day.......we seem to have things under control until the weather is nice and the 2 dogs spend time outside in the sunshine. Two nights ago was the worst--our 15 year old cockapoo had hundreds of fleas on him after being out in the yard for a couple of hours, and the day before I'd only found 2 or 3 when I combed him. Our cats that stay indoors do not have near the flea problem the dogs have.....a few fleas when I comb them, so we feel like we are making good chemical-free progress inside the house.

This product is not all that easy to use, but it works, so no complaints. My strawberry bins were filled with grubs. Also, the garlic and onions. And, I mean there were countless white grubs. Anything that has copious thread-like roots was affected. My husband and I, late one night, sprayed down everything. Several weeks later, I dug around in all of the bins, looking for the little monsters. Nothing. No grubs anywhere. This product works. Don't worry about the hassle involved with it. It works. That's all you need to know.
