Gentrol IGR Aerosol ZOE1005 16 oz, 1,200 sq ft Treatment - with USA Supply Gloves and Pest Identification Card - Disrupts Development of Cockroaches and Bed Bugs

ATTN RVers: This is the best spray ever for sewer flies/gnats! I needed flexible tubing (not provided) to not have to hold the can upside down to spray down my drains. I was able to order a size that fit the nozzle on Amazon. Now my RV will be sewer fly/gnat free this coming summer. I've already managed to get it down the drain with the can mostly in an upright position and so far it has worked magic in my gray tank. That's where I think they hatch or whatever. They start appearing inside as soon as it warms up. My shower is the only non-covered drain they can fly up and into my RV. I plan to spray every other day for 2-3 weeks to conquer all stages of their life cycle. So far, I'm amazed with how few there are. Not quite zero yet but I'm getting there. Excellent product!!

Used along cabinetry cracks, behind refrigerator, and in their hotspots. Very effective. Doesn't kill them immediately but it sure confuses them and definitely alters their body plan by destroying the wings of the adults. For those who don't know this is essentially birth control for roaches. This in combination with a plan that involves sealing passageways, removing food and water sources, applying insecticides like Alpine WSG, and just generally keeping a clean home, will solve your problem. Get yourself some on contact kill solution like Raid, attack the nests, clean up the dead bodies, and apply the Gentrol. You want to physically remove as many as possible before you apply pesticides. If you rent your landlord probably doesnt want to pay for real pest control. If you go to them your subject to home inspections and to them blaming you for what is likely a structural problem they dont want to pay to fix. If you're not ready to move or fight your way out of a lease, then you can do it yourself with the same stuff the pros use. And no, treating the problem rarely makes it worse. You're going to be driving the roaches out of hiding which may make it seem worse. The worst thing you can do is ignore the problem. I know its gross. But glove up and dive in because it doesnt get better by ignoring it!! Do your reasearch and always follow the label. One can is enough for I think 1200 or 1600 sq ft. Ps if you have an old refrigerator that you cant afford to replace, buy some 200 mesh (or .5mm) and seal the exposed parts off AFTER you have largely exterminated the problem. Stick traps are your friend. So is boric acid. Boric acid shouldnt make other treatments less effective so long as you wait for treatments to dry before adding new ones. Basically dont throw acid powder onto wet gentrol.

Work great

We are landlords and we have tried several products. This does work as long as you spray as directed and use every several months.! It really does keep the roaches away! We use with other Gentrol products to be more effective and efficient.

This stuff works. Not right away but after a few weeks you will notice the roaches wings are deformed which means they are now sterile & can’t reproduce. This works great with Advion gel bait. The spray is more effective than the discs, but it’s barely enough for a small 1 bedroom apartment. Get at least 2 bottles.

So I’m not sure what kind of roaches are in my house but after other products I purchased this and advion bait traps and noticed a huge reduction in the amount of roaches I see. It does not instantly kill them nor does it advertise that it does but as the roaches travel through the area sprayed it slowly begins killing them. I find them randomly struggling to crawl or dead and it’s to the point now that all I see is babies. It’s been a month since I sprayed and this is everything I’ve observed. Price is reasonable and the spray straw makes it perfect and easy to use. Ordering my second can after this review to knock the babies out.

I have a terrible German roach infestation. I don't know how because I'm very diligent about cleanliness. These were so bad that when I turned the light on at night, they would scatter by the dozens. Floors, counters, everywhere. I tried many different products such as traps, baits, foggers. Nothing worked. I bought this stuff along with Alpine wsg. I vacuumed, washed everything and then sprayed. First the Alpine and then the gentrol. It has been four days and so far I have not seen very many roaches. I'm hoping that the few that are left will be eliminated through the treatment. It has definitely made a huge difference and I'm going to buy more to keep on hand. Update: I still have my roach problem, but not as bad. I just did another full treatment with the Alpine wsg and gentrol plus deep cleaning. I'm hoping this will get rid of what is left. I have definitely noticed a decrease since the first treatment.

I used the Gentrol aerosol along with the round stick-on pads from the same company that are supposed to affect female roaches, and honestly I think the roaches in Florida are using it for shower gel. I gave it two full months and used both products together. I put those pads everywhere. It didn’t make a difference. If you live in the South, especially Florida, and you’re dealing with American or German cockroaches, this alone probably isn’t going to cut it. I eventually had a professional come out, and I’m not talking about a little handheld sprayer around the edge of the house. They sprayed somewhere between 50–100 gallons of pesticide across the entire yard and around the home, really saturating the property. That made a big difference in preventing roaches from coming in from outside. After that, I started tackling weak points inside the house — replacing a trash can that didn’t fully seal, making sure no dishes were left overnight in the sink, rinsing cans before throwing them away, cleaning toaster crumbs, all of that. That combination is what really brought things under control. Using Advion gel bait (the syringe tube that looks like peanut butter) also helped when placed in targeted spots like behind the toaster, near the coffee pot, and in the bathroom where there’s moisture. After staying consistent, it got down to maybe spotting one or two a night. Bottom line — nothing wipes these out overnight, especially in Florida. For me, this product didn’t make a noticeable impact compared to the other steps.
