Pro Tips Fenva Star EcoCap is a product I often reach for in our retail store. It is labeled for a wide variety of insects and is really economical to use.
I don't like it so much for German roaches. The roach baits are the way to knock those guys out.

- ain't doing it
Have treated area 3 times... still have fleas. No pet access or other activity...
Fleas can be difficult to eliminate. Fenvastar EcoCap is a good choice to kill the adult fleas but it should always be used with an Insect Growth Regulator (IGR) for control of the pre-adults. Feel free to contact us at 800-476-3368 for our recommendations.
- Good product
This product didn't have an odor that we noticed or was objectional. It was effective in killing fleas. You have to use the IGR with it which we didn't do the first application.
I had fleas all over the house thanks to my little cat. I started with vacuuming and then sprayed with FenvaStar EcoCap mixed with an insect growth inhibitor (Tekko Pro IGR); and left the house for 4 hours. Very little odor. I did not wash the floors for two weeks, just left the spray to dry and do its work. After the initial spray, I waited two weeks while watching for more fleas. They showed up, but were seemingly weakened. I vacuumed and washed the floors and sprayed again with the same mix and haven't seen any more fleas...yet. It has been almost three weeks since the second spray. I am ready if I have to spray again, but hope they are gone for good.
Thanks to DIY Pest Control this nightmare seems to be over.
- It does not kill fleas
Finished the whole bottle in our garage (applied twice). Followed instructions but fleas are still alive. Dont know what to buy anymore. I bought this product based on the reviews but I guess this product was not meant to kill fleas.
- I would recommend this product.
It is effective on contact. I use it for flies and bedbugs.
- Effective product at a great value
My neighbor paid $500 for a professional pest control service to rid their wooden play set of carpenter bees. When ours became infested I searched the internet for appropriate solutions and FenvaStar EcoCap is an effective first step in a two-step process.
All together I spent $44 and the bees haven't come back.
- Very Good Product
I have purchased 2 bottles of FenvaStar. It works effectively. Not much odor. Easy to understand instructions. For mixing water, it soaks the areas that are being sprayed. I would recommend this product to anyone.
Bought this because my neighbor got roaches and inevitably so did we as we share walls. I have children and am scared for them. I sprayed with 2oz. mix and they were still here, waited a week sprayed same again.... Guess what they are walking thru it as if all I sprayed was water. I am also using Gentrol, Max force bait stations, Max Force bait in both apartments. What am I to do now?!? I don't sleep, eat or even function. I cry all the time, I cannot move because of lack of money. This pretty much sucks!!!!!!
DIY Response: Sorry the FenvaStar didn't work for you. While cockroaches are on the label for FenvaStar, the MaxForce and Gentrol products are a much better solution, but they do require time to work. The Maxforce Bait is for killing the adult roaches, and the Gentrol is used to sterilize the remaining live ones so are unable to reproduce. If you need assistance please call us at: 1-800-476-3368
- Flea invasion
Product works...would give in 10 stars.
- Low odor, killed like a thermonuclear weapon, but does it last?
Bought this product to fight a flea infestation. After living here for 11 years with no fleas, they made up for it this year. Bam! Fleas everywhere, almost overnight. If you've never had fleas, they are nasty little buggers. After wasting money on the usual useless junk from the local big box stores, I came here to get something that would work.
DIY Pest Control shipped *fast* and I got it *fast*.
Mixed it up per the instructions - 2 OZ per gallon and sprayed the house. It has a small smell, but nothing overpowering. This made the family happy, as we had expected it to smell awful. But it didn't. :) My wife even commented that she was pleasantly surprised that it didn't smell. This probably saved me the cost of a hotel room for the night. ;)
Like a small thermonuclear weapon, it seemed like it killed everything with nothing having survived. Far better than the worthless garbage from the big box store.
About a week later, we're seeing some additional fleas around the house that I probably missed in the first spraying. (I did combine this with Meteor IGR, so that's the only thing I can figure.)
Question for the pros - I've seen some fleas happily bouncing thru the areas where I had sprayed. Should the residual product kill these guys? Or am I seeing them happily bouncing around minutes before their untimely, accelerated deaths?
Answer: Yes, it does take a few hours for the insecticide to enter the nervous system of the flea to kill it.
- Does not work for carpenter bees!
I ordered this product for the control of carpenter bees. I have applied it generously twice and it has not helped at all. Please advise if I have purchased the wrong product.
Sorry to hear you're not finding the product effective. The goal in Carpenter Bee treatment is to stop them from damaging your house. FenvaStar EcoCap is a suitable treatment for this goal. FenvaStar is a repellent and it keeps female Carpenter Bees from drilling new holes. It will also kill them if they land on it, but they can detect it and typically wont land where you have sprayed it. Its also normal to see the males fly around after application, but they are harmless. If you have existing holes that are problematic, give us a call at 1-800-476-3368.
- Great stuff!
I have used this product for over a year now. Encapsulated products ARE the way to go for good pest control. I had a company come every month and had bugs. I did some research, then bought a sprayer and have done my own from then on. FenvaStar EcoCap is MY choice for pest control because it is so flexible. For general pest control I use one once per gallon of water. During the summer I bump it to two per gallon and have not seen a bug in a LONG time. I do crack and crevice treatment as well as treating the voids under my cabinets. It has worked for me. There are a lot of good choices out there but if it's not encapsulated I won't use it.
- fenva star on fleas
Fenva Star eco cap kicked the crap out of the fleas in less than a week and they're still gone. Great product nuff said
- Three days and itch free
I made the mistake of talking home a used mattress. So about 2 weeks went by when I realized what my bumps where from. I saw a live under the mattress. I disposed of the bed and spayed it with Bedlam (the frame). I lifted up my carpeting and added DE Dust. I thought that'd be enough but, 5 weeks passed and still getting see bites.
So I bought this last week and mixed with Gentrol (BB birth control). Didn't notice anything the first day, second was less itching, and third day no itching. I also spayed my whole outside building, porch. My dislike is the smell, it makes my noise run too..
A great product for bed bugs. I wish I knew about it before I spent all that money on stuff from the hardware store THAT DIDN'T WORK!!!
I have worked in the pest control industry for a little over three years. This is what I use to treat my apartment. During the summer monsoons I bump it to 2 oz per gal and drop it to 1 oz during the fall, winter and spring. It has proven very effective. I am sold on the effectiveness of micro-cap insecticides. During the hot summer months they are the only product worth buying.
