growth regulator or roach gel

0

After reading your article on roach control, I’m planning to start gel baiting for German (and possibly Brown Banded) Roaches in my kitchen and bathroom cabinets. I think my infestation is light to moderate – I hardly see any droppings and haven’t caught more than 24 live roaches on any given night. I’m thinking about applying both Advion and Maxforce separately around the rooms, rotating them with each treatment. Do you think this is overkill and I should use a single product? Also, I found Gentrol Point Source Insect Growth Regulators in gel bait stations. Will this help break the reproduction cycle or will the Advion/Maxforce gels be effective enough? Many thanks and compliments for a great website on roach control!!

Thanks for the feedback on our site. No doubt we know roaches and which products work best when trying to treat local problems. And to get right to the point, when using any growth regulator with a bait things can get a bit dicey. I say this for many reasons. Though the use of growth regulators for many pests has a proven and tried track record, there are some variables that can effect the way it’s perceived once applied and part of a regular pest control program. This list is outside the scope of general information we make available on this site so I won’t bore you with all the details but I will elaborate a little. My quick answer is I would not recommend employing both options. Stick to using just the GEL or just a spray with GENTROL added or just the Gentrol by itself.

To elaborate on this a bit, here is a brief guide on what to expect if you were to use either of the three approaches independent of one another. The three approaches would be Growth Regulator, Spray (adulticide) and Bait (Gel, Stations, etc.). The “growth regulator only” treatments can solve problems. But I’ve seen where this can take many months and in some cases a year or more to complete. Remember, growth regulators don’t kill roaches. And though they prevent them from fully developing into reproducing roaches, it’s quite possible to have a never ending influx of new ones which may not make it to a reproductive age but will be visible to the resident. Suffice to say this is not an “acceptable” level of control by today’s standards. One can argue the product is working but if you (the resident) are still seeing roaches, so what? The goal of roach control is to make them go away for good and whether you’re seeing juveniles or adults they both incite a similar feeling and one most people are not comfortable feeling day to day. And remember, with the Gentrol preventing the roaches from growing up, many will be stalled in a stage where they won’t want to eat anything. That means even if they are close to a bait you’ve applied it can very well mean the growth regulator will prevent them from actively feeding on your placement. These are just some of the variables that make the use of a growth regulator dicey and unless the user is fully aware of what to expect when used, we know it’s best if the “newbie” to pest control stay with one or the other for the sake of making the process easier to accomplish and understand.

So in the big, long term scheme of things, the use of a growth regulator by itself can solve problems but it will no doubt be the slowest of the three approaches. Additionally, it can in effect “drag on” a situation which could otherwise be cleaned out quite quickly. And the way to get rid of the roaches quicker can be done with either the Gel or a good ADULTICIDE. Now when we look at these two approaches, we find the spray can be the most acute and fast acting. But we also know if the applicator is not skilled enough to make precise placements where it matters the most, the local roaches will continue to thrive. Add to this the problem of “interference” (interference is what I describe as obstacles that get in the way of spraying effectively like food, boxes, utensils, appliances, etc.) the overall effectiveness of the spray is continually diminished once someone sets out and uses some. So yes, spraying is no doubt the fastest way one can achieve good success when dealing with a roach infestation. But unless the structure is completely accessible such as one might expect when moving into a vacant apartment or home, it’s best to skip over this option and go with nothing but bait.

And as our ROACH CONTROL ARTICLE explains, baits are both easy to apply, do not require any major preparation to the areas where they’ll be used and when set out properly, can be used so discreetly no one will even know they’re present. Add to this the way it works (gels will actually lure roaches to it) and the fact that you don’t have to apply it with surgeon like accuracy, it’s easy to see the advantage of using this approach. As for the time it takes for a baiting program to work; it will be middle of the road compared to an adulticide only or a growth regulator only approach. But because it’s so easy to deploy and maintain, it’s the clear winner for most anyone in a residential situation where they need to do some roach control.

Sorry for the long winded answer but trust me, this is the scaled down version :-)  The bottom line is using both ADVION and MAXFORCE alone will no doubt knock whatever roaches you have for a loop. In the end this is all you need so go with this approach and I’m sure you’ll be satisfied.
