I HAVE LAKE FRONT HOUSE, SPIDERS ARE ALWAYS A PROBLEM … THE QUESTION I HAVE IS HOW LONG DOES THE ECO EXEMPT CONCENTRATES LAST IF I SPRAY MY HOUSE ALL AROUND IN THE LATE SPRING THANKS B.H.
We’ve had people report residuals from two weeks to two months. It’s really hard to say. After being in the business for over 30 years, I’ve learned residuals can vary from house to house based on what’s going on locally, and most importantly, what’s happening on the property being treated. In the end, I think it’s mostly dependent on the local moisture levels and there really is no way to tell for sure other than to try.
For example, here at my house, the length of residual has varied by almost the exact difference cited above. When I first moved to where I now reside, I found my treatments lasted about 2 weeks. This was true for most all the pests found on my property including spiders. I live on a river with lots of lush vegetation, shade and moisture so no doubt I knew it could be tough to get products to last when I decided to move here. But being in the business (and the fact that I can get a good price on the products I sell), I was undaunted. For the first few years I found I was treating about every 10-14 days “in season”. But then we started to have a major drought a few years ago and by the second year of the drought, I noticed my treatments could go much longer and still be effective. Interestingly my lot wasn’t that much different from before. In other words, it was still lush and green and shady. I’m thinking the plants were getting their water from the river bed. But I’m pretty sure the lack of rainfall combined with the lower humidity allowed the spray I applied to last a lot longer and in the end I was able to go just about 2 months before needing to retreat.
Now will that be what you can expect to happen if you were to apply ECO IC around your house? Probably. There is no doubt the length of residual for any product is dependent on factors like the rain, sun and general air moisture. But I would be amiss not to mention the impact a complete spider treating program would provide. In other words, if you were to treat the yard with the ECO GRANULES and spray the outside with the ECO IC CONCENTRATE, no doubt you’d get much better results compared to just spraying. And for obvious reasons, if you have spiders inside the home, treating with some ECO KO AEROSOL inside would be a big help opposed to just relying on the outside spray to keep them out.
So in summary, there is no doubt a lot of factors that can all have an impact on just how long any one concentrate or treatment might last. In the end you will undoubtedly find it to vary from year to year and even from season to season. But if you stay the course and treat the property for several years, over time you’ll learn just what to expect given the current weather pattern during any one year. Personally I’ve got my lot down to a science. I’m able to gauge within a day when certain pests like mosquitoes, spiders and ants will “reappear” and it’s mostly dependent on the local moisture levels. No doubt it has fluctuated and I suspect the same would be true for you as well.
