Gentrol Point Source IGR Discs ZOE1007 (20 Pack) German Cockroach Growth Regulator - with USA Supply Gloves & Pest Identification Card - Product is Non-perishable

If I could give it more stars I would. For anyone doubting this it absolutely works just give it time. I rented an apartment that had a years long infestation of German roaches. With Gentrol and Advion Gel and some elbow grease to clean the place here I am a couple months later completely roach free.

We noticed and influx of water bugs and were wondering what was going on. Well there was a slow leak under the kitchen sink and went on over to the dishwasher. This will not work alone. You need to lay down a good gel bait in small drops so the bugs can eat it and take it back to the nest to kill them off. This stuff makes them sterile and they can’t reproduce. It’s been one week since I put these down and haven’t seen a cockroach since. If you have a bug problem I highly suggest you get this product asap.

I really don’t know if this product actually works I’ve always used it in conjunction with an exterminator. However, I will say there is a comfort the in knowing that it controls or decreased the life cycle. Which is a plus for me and I buy it again. Very easy to use, odorless , last a long time. Very functional and practical size for area where you want to use or hide these. Great value

Gentrol is a wonderful product. I use this along with their IGR solution/spray to stop the growth of critters I my apartment. I will continue to purchase! Smell: No smell at all! Value for money: Discs cover a pretty large amount of area so you don’t have to use more than 1-2 per room Functionality: Easy to use. Just use the stickers (included) to stick them where needed. Adhesive is sticky enough to last for months.

We haven't seen the pantry beetles that were plaguing us for a few months now. I hesitate to say that because of the old superstition that mentioning something is going well just brings the problem back down on you, but it's true. We changed these out about three times, kept cleaning out the colonies as we found them, transferring tempting food sources to more secure packaging, etc., and it does seem to have been effective.

Research has shown that one female cockroach can reproduce one million roaches in six months. Imagine how many babies one hundred female cockroaches could reproduce in six months. Cockroaches can live up to seven years depending on the type of roaches in the infestation and the surrounding environmental conditions such as available food, water sources and the abundance of places for them to safely nest. This rapid reproduction factor combined with their potential longevity are two of the reasons that cockroaches are so hard to get rid of - especially German cockroaches. However, if we can eradicate roaches on these two fronts we can shorten the time that it takes to get of a roach infection. Realistically, one should allow between three to six months to completely eliminate a roach infestation. GENTOL is not a poison; it is instead a growth regulator that that prevents prepubescent roaches from reaching full adult maturity, thus making them incapable of reproducing. This can greatly shorten the time that it takes to get rid of any roach infestation. GENTOL works best when it is used in combination with a poisonous gel. I have chosen Advion Cockroach Bait Gel as my preferred poison. This gel does not immediately kill the roaches. Therefore, it allows more time for them to carry the poison back to their nests where it will kill off the baby roaches. And, because roaches wil often eat each other these cannibalistic roaches, who eat these dead poisoned roaches, will consume their poison and die soon thereafter. Amazing results can be achieved with Advion Cockroach Bait Gel within three days, as you most likely will find hundreds of dead roaches everywhere that Advion Gel has been properly applied. These two companion products should be administered as part of a predetermined three to six month program; even one overlooked egg-bearing cockroach can start the cockroach infestation all over again. How long it takes to get rid of a cockroach infestation depends on the extent of the infestation, the type of cockroaches that you have, the quality of the irradiation products that you use and how effectively and diligently you apply them. And, keeping one's home environment as clean as possible will also contribute to a faster elimination of an infestation. The tiniest crumb can become a feast to a hungry cockroach; these tiny and often unnoticed food particles can also lure roaches away from the poisonous bait and thus can significantly extend their life expectancy. Don't wait! Cockroach infestations can spread very quickly. And, the longer you wait to get started the harder it will be to get rid of the infestation. Cockroaches are not only unsightly, they can also be extremely dangerous to your health. Their feces can cause serious allergenic bronchial infections and they can also carry dangerous bacterial and staff diseases. I will provide an update to the efficacy of GENTOL after three months of continued use. But, for now I am very satisfied with GENTOL and Advion Cockroach Bait Gel. After only two weeks almost all of the visible cockroaches are gone. Both of these two companion products can be purchased from Amazon. I highly recommend these two roach eradicators and give them both five super big happy-faced stars.

This definitely works for getting rid of roaches. We had tried sprays, diatomaceous earth and roach motels. All helped but, didn’t get rid of the roaches. Gentrol works well. Takes time due to the roach life cycle. It has resolved our roach ingestion in one month after a five month battle.

Did absolutely nothing to even slow them. Not 1 deformity after 2 months. Babies is what I seen more of. I placed 3 in my tiny bathroom and the rest in my kitchen. Not worth it, don't waste your money.
