Bed Bug Supply Review - see what our experts have to say about this product

Bed bugs, cockroaches, and many other household pests are capable of laying several eggs a day. This rapid reproduction ability makes fighting an infestation very difficult - cutting down the population does you no good if they’re just going to come back shortly after.

This is why pest control professionals are turning to Gentrol. Gentrol is an insect growth regulator: juveniles that are exposed to it become unable to reproduce as adults. Gentrol can be used in its own spray, or as a tank mix with an appropriately-labeled adulticide. It has been proven effective at inhibiting the reproduction cycle of bed bugs, beetles, flies, moths, and roaches.

We really like that Gentrol can be used in a mix with certain insecticides, as this makes it very easy to include in a treatment. We’ve gotten great feedback from our professional customers since we began carrying it, and we will happily continue to recommend it. Homeowners might also consider Gentrol Aerosol, which (as the name suggests) is the same product in an easy-to-use aerosol form.

Product Information

Gentrol is a revolutionary insect growth regulator. It uses hydropropene, a synthetic juvenile hormone "look-alike", to disrupt pests' normal growth pattern. Juveniles exposed to Gentrol will be sterile as adults, thus stopping the constant cycle of reproduction in an infestation.

Gentrol is a popular choice for use against German roaches and bed bugs. Since both species can lay several eggs a day, controlling their population can be immensely difficult. Gentrol helps stop the endless cycle of reproduction that makes an infestation so hard to beat. When used in combination with an insecticide spray, Gentrol can be the difference between success and failure when attacking a pest.

Using Gentrol is simple: just mix 1 fluid ounce in a one-gallon sprayer, shake and stir the solution, and start spraying. Apply Gentrol to places such as walls, floors, ceilings, attics, basements, or crawlspaces.

When doing a bed bug job, use either a pressurized spray system capable of delivering a pinpoint or variable spray pattern, or a device capable of coating evenly. Make crack and crevice applications to wall voids, baseboards, floors, and ceilings. Make spot treatments to areas such as storage spaces, closets, doors, and under furniture and beds. You can treat the underside of the bed's box spring, but don't apply Gentrol to linens or mattresses.

Bought two applications. Used first bottle with first round of treatment. Will use second bottle in two weeks. Again, we haven't found bed bugs but based on previous tenant, she claimed they were present. A friend recently got a job with a pesticide treatment company and claims this is a good route to go for treatment (he was unfamiliar with this particular brand) but in his training was told this is definitely a positive step in the process of treating for bed bugs. We have 4 more weeks of treatments we plan on doing. This is a vacant propertly, fortunately or unfortunately but we plan on using interceptors with a bed frame and blow up mattress and using our bodies as lures after the treatments are complete. Believe our little friends may be in hibernation. We know more after another month of treatment. Bed Bug Supply suggested we call if we had any questions and they would be there for us if we needed additional assistance. Good Company!
