The BEST bug spray I've ever had
Seriously, what a blessing it has been to have found FenvaStar EcoCap. This stuff kills all the stuff that Ortho can't even touch. I now find all my crickets and roaches dead instead of alive. It is great! This is the third online review I have ever written in my life. But I had to do it because I LOVE THIS STUFF!

excellent product
I used this product to get ride of bed bugs, at first i tried everything an i spent more than 250.00 dolars en other brands. After the first application, i wait 3 days and sprayed again at list for 2 weeks, now after a month my house is clean of bed bugs. I am able to go back to sleep peacefully. I am going to be using this product once a month for precaution. The other important thing is that doesnot stain the walls or carpets.

I used this FenvaStar EcoCap product in controlling the existence of bedbugs in my home. It worked pretty well. I would definitely use this again if ever they come back.

insect treatment
Fenva star is the best insecticides I have ever used. I had my son’s birthday party indoors and outdoors and since all the doors and windows were open a lot of cockroaches, insects and flies got inside. I had ordered fenva star as an emergency product a week before the party. All the guests were very annoyed with the insects. So I moved the party outdoor and sprayed fenva star inside the house to kill all the insects. After 30 minutes I found all the insects were dead! Then after some time I moved the party back in and sprayed the outside lawn and miraculously fenva star worked outside as it worked inside.

Generic Onslaught
I am professional exterminator. I know that the ingredient used in FenvaStar EcoCap is Esfenvalerate 3.5% which is a strong ingredient and works great against many pests. It works against Ants, Bees, Carpet Beetles, Centipedes, Cigarette Beetles, Cockroaches, Confused Flour Beetles, Firebrats, Fleas and Ticks. I bought 12 bottles of FenvaStar EcoCap insecticide $ 263.40. I always had to use 1 bottle against severe infestation but with FenvaStar EcoCap I only had to use a little less than 1/8 the bottle! FenvaStar EcoCap is the best product available in the market for such a low cost. I would definitely recommend FenvaStar EcoCap to others.

do it yourself products
FenvaStar EcoCap product is so great. I recently moved to Arizona. The house I am currently in was highly infested with roaches. So I bought fenva star eco as per the recommendation by our local pesticide store. It works well. All the roaches were dead after two nights.

do it your own pest control
I am grateful to FenvaStar EcoCap for saving me from that kind of sickness.

microencapsulated products
FenvaStar EcoCap uses micro-encapsulation techniques. I am allergic to bees and their bites. But the bees would always come in spring and try to form a hive in my garden. I once got bitten by a bee and was bed-ridden for over a week. I ask my brother to treat the bee hive with FenvaStar EcoCap for me every three months. I found several dead bees in the garden after my brother gave his last treatment.

microencapsulated insecticide
I was thoroughly impressed by FenvaStar EcoCap’s performance. This is a highly recommendable insecticide.

5 of 5 Stars! (5/5)    Review by   Theodore Kemp  (Posted on )

FenvaStar EcoCap is the best insecticide ever. I had the biggest bed bug infestation. I bought FenvaStar EcoCap online and applied it the day it was delivered. The next day I found that there weren’t any more bed bugs biting me at night! I can confidently say that FenvaStar is one of the best insecticides. I even found the spiders and cockroaches dead. I would always suggest others to use FenvaStar EcoCap.

5 of 5 Stars! (5/5)    Review by   Marguerite Goodman  (Posted on )

There was a cockroach infestation in my house which thoroughly disgusted me. The local pest control company had given the infestation several treatments. The cockroach infestation would go away for some time and then come back again. I had already spent several hundred dollars and so I didn’t want to spend a single more penny on exterminators or pest control companies. I started to use FenvaStar EcoCap. That was it for the cockroach infestation. FenvaStar EcoCap’s effects lasted till three months which is a long time compared to the lousy work other insecticides do.

Do You Have a Question about this Product? Ask Our Experts!

Sort By :
Q. I guess due to a very mild winter we are experiencing a excessive amount of Gnats of all kinds what do you recommend to get rid of these
A.   Fly light traps are a safe way to control flies and gnats. For gnats that are smaller, the Flyweb Light is a good way to control them. If you are looking for an insecticide, consider using FenvaStar or Lambdastar 9.7. IF either product is applied indoors, it is important that you let the treated area completely dry before reentry. If you have any questions, please feel free to contact us again.

Q. Bedbugs
Can this be used on bed bases for bedbugs ? Does it smell and does it dry clear?
A.   Yes, you can use Fenvastar EcoCap for bed bugs. It does not have a smell and it dries clear. Please keep in mind that it is not to be used on the mattress itself. If you have any questions about the products or bed bug control, please feel free to contact us again.

Q. esfenvalerate
Does this fenva star have an "expiration" or "best by" date? Thanks
A.   Liquid concentrate insecticides generally have 1-2 year shelf life depending on how you store the product
Was this helpful?
Q. Does this kill all stages of carpet beetles; larvae, eggs and adult?
A.   That is not labeled. Most insecticides, though, will not actually kill the eggs directly. However, because of the long residual of Fenvastar, when the eggs hatch, the chemical will kill the larvae on contact.
Was this helpful?
Q. how do you mix this product up and can you also mix up with something to control the eggs and reproduction.
A.   Generally, you would mix the product with the appropriate ratio of water depending on the target pest. The ratio mix is on the product label. You can also mix the product with Gentrol IGR to regulate the growth and reproduction of the insects.

Q. Invasion of outdoor moths
I am having a terrible time with outdoor moths that eventually get into my home. In all the time I've lived here never had this been a problem before. Do you have a product line that could be sprayed outside to try and eliminate the population that seems to be growing daily. Please reply if you have an answer to this problem. Thank you...Jane
A.   We recommend using liquid insecticides such as Lambdastar to spray onto areas of infestation.

Q. How long is the residual effect? I am planning to use this as a bed bug treatment for my apartment. Also, I am currently using Bedlam as well. What are the steps you would suggest in using both products together? Which first and how? Many thanks!
A.   The residual for Fenvastar indoors is about 3-4 months. We recommend treating the furniture frames, in between the mattress and box spring, and those tight areas with cracks and crevices with Bedlam first. Wait till it completely dries. Then apply Fenvastar in other broad areas like the baseboards of the room, under and behind furniture, and etc. Wait till the area completely dries before reentry. If you have any further questions or comments, please feel free to contact us again.
