    roaches and bedbugs

    By Nicole on 09/15/2017

    I got a used rolled up area rug from a friend and next thing I knew I had roaches. Called an exterminating company. They came for six months. They kept they population way down but didn't seem like it would end up being a permanent solution. Found this website and used the Gentrol along with gels and bates and the were gone in a month! Two months ago my daughters friend spent the night and when her mom picked her up she said "oh by the way we have bedbugs" yeah she really said that....six days later I saw what looked like a nymph on my shoulder. I sprayed with IGR mixed with Temprid SC. I saw what I believe was another nymph a couple days later and almost two weeks bites showed up on those spots. I am spraying still 8 weeks later but have seen nothing since. I know there probably weren't many but I'm continuing to spray. This stuff works great. Highly recommend!

    Igr

    By Eric on 05/01/2017

    Stop the cycle. As a professional applicator I understand how important it is to stop the breeding cycle. This product does exactly that for roaches and bed bugs.

    Thank goodness for this product!

    We purchased this product at the suggestion of a friend in the business. After buying a small lakeside cabin for cash we realize that at some point it had had a bedbug problem. We received a professional

    Awesome product!

    By Michael on 05/11/2017

    Purchased a used mattress (epic failure) unfortunately, it brought bed bugs in my home. Awful. Tried other products, waste of time and money. Purchased Gentrol Igr concentrate and a major difference. Only seen one bug since. However, another treatment is due so I feel confident this will do the job for sure. For the price I purchased 2 bottles treated 3 rooms and plenty more to finish with so worth it! I recommend this product for small infestations that's caught early such as my situation.

    Works Great!

    By Antwan on 07/20/2012

    I bought this along with the Borid Boric Acid and it works great. Personally I liberally sprayed it all across my kitchen floor, inside my cabinets under the sink (where I suspected they were hiding), behind and under the fridge and stove, and in all cracks and crevices. Then I waited until it dried. Then I applied Borid Boric Acid around all baseboards, under cabinets, behind and under fridge and stove. This killed the roaches by over 95% within 2 days.

    black worms in my NEW shower!

    By D.b.s. on 03/19/2013

    Verified Purchase

    We had a new extension put on our house a year ago. We added a bathroom on the second floor. One day when I was cleaning the shower, I noticed these black small worms coming out of the grout. There were hundreds washing out when I squirted water along the edge. I tried everything I could think of. I finally found this website and bought the hotspot, it eats up organic matter that the drain fly larvae feed on. It also drew them out of their hiding space and I was able to kill them. I would still see a few, so I called up "domyownpestcontrol" and they suggested buying the Gentrol IGR Concentrate. This doesn't allow the larvae to mature into a fly, and thus cannot reproduce. I bought a squirt bottle in Target and diluted the Gentrol with water. I did this treatment a total of 3 times. (You have to wait 10-14 days for each application). Yay!! Finally I am drain worm free!! I can't believe I finally conquered these things. They are so hard to get rid of. They weren't coming from my drain, they were in the tiniest crack in the grout in the shower floor. I am so happy I found this product and the customer service representatives were so helpful and nice. Thank you!!!

    Wicked stuff

    By D. on 04/27/2016

    I bought a house that had a heavy infestation. I mixed this stuff with the Suspend SC as directed. By the end of the first week after spraying I was seeing very few roaches, but the ones I did see were scary looking. Looked like a cross between a roach and a cricket. By the end of 2 weeks I was seeing one or two per week. I am continuing the follow sprays as directed. Not expecting my problem to show it's ugly head again.

    Best stuff ever

    By Lou on 03/06/2019

    I live in a small apartment rented out by a true slumlord. Needless to say bug infestations in this building are (were) commonplace. About 18 months ago I bought Gentrol (pint), Viper (pint), and Demon Max (gallon). I alternate between the Viper and Demon always using Gentrol with them and spray monthly. It took about six months (the bugs were really bad and the slumlord ignored tenant complaints) but I have been bug (every kind of common roach and bedbugs which invaded from other units) free for about a year now. I sprayed all potential entry points (from the other units), completely around the perimeter and especially around plumbing access hatches, under sinks, stairs, and door/window frames. Now only the other tenants are complaining and the slumlord has started to listen to them but his "bug guy" wants to spray all the units (or at least so says the slumlord) for his "100% bug free gaurantee". This is a "professional" who doesn't even use IGRs. I think I'll just stick with what I've been doing since this is is the best product (in tandem with a knockdown agent) that I have ever used. I decided to finally write a review because I'm back to buy more Gentrol.

    The Mighty Roach War

    By Med12 on 07/05/2014

    It seems to be working well. Recently moved into a new place and didn't notice till it was too late that it had a pretty established german roach population. Initially I sprayed with talstar-P. It killed a lot, but more were always coming so I purchased Gentrol and sprayed with a mix of the two. I still see an occasional roach now about two weeks after spraying BUT it is usually dead.

    Could not Have worked better !

    By Steve on 03/19/2017

    I own a trailer park and have spent as much as $700 to get a professional to rid one rental of bedbugs . We own 6 trailers imagine what our expense could be . I found out what the pro used ( Zenprox and Gentrol IGR ) ,made my purchase from DoMyOwn PestControl and have saved thousands since. Renters constantly bring home bedbugs with goodwill furniture . Here we have solved a big problem very economically . KUDOS ! Thank YOU !

    This is the key!!

    By Josie on 05/30/2017

    I've researched online and this is what you need to stop roaches from reproducing in the future. Gentrol is very effective and the people at this company helped me out very much with information. Don't waste your money buying insecticides at the stores. Do you want something that works? This company has it all.

    By Cindy on 07/12/2019

    This is a great product. This product got rid of my bedbug and roach infestation for good. I saw a decrease in there number after a one time use. With in two weeks they were completely gone. Genetrol is a must have if you want to illuminate a bug infestation because it stops the ones that the insecticide doesn't kill from reproducing.

    Works well on German Cockroaches

    By Charlie on 12/16/2012

    Verified Purchase

    This was for my son's townhouse that was overrun by German cockroaches. I made my own kit by purchasing Gentrol IGR Concentrate, Maxforce FC Magnum and Demon WP Insecticide. They used these products and said they noticed a huge difference by the next day. They are going to apply two more times at two week intervals. I think that may wipe them out completely. I highly recommend these products.

    Great product

    By Bill on 02/10/2013

    This product just palin works on german roaches. It is not an overnight cure, it takes sometime and multiple applications. Used with a good pesticide does wonders. You will need more than a single bottle grab the 10 pack, you wont be sorry.

    This is used to prevent eggs from hatching. It truly does work. Also, the do it yourself pest control in my area charges three times the amount for thus product. Its cheaper to get it here. Plus, they will talk you through it over the phone.
