We have a log cabin in NY (Adirondack Mountains) and need immediate help with porcupine control. The logs are pressure treated and the porcupines have been causing damage on and off for several years. It is getting serious at this point and I need to get rid of these pests. I have looked at your website and products but am unsure which to purchase and which are most effective – Ropel vs the Liquid bird repellent. What are your recommendations?
Both products can work but the ROPEL seems to be the weaker of the two. That being said, 4-THE-BIRDS can be unsightly so there is the cosmetic impact that needs to be considered. 4-the-Birds goes on like a thin layer of glue and will remain looking this way for a long time. Gradually it will absorb into the wood but in many cases it can make the wood appear darker, kind of like it's wet, and this look can become permanent. That being said, there is no doubt wood treated with it will stop the porcupines from chewing.
So really the question is what you're comfortable trying. If you prefer to not alter the look of the wood, start with the Ropel. Worth mentioning in another product we've had great results with called PEST RID. It's a natural repellent that works via taste and smell and we're getting very good results with it for Porcupines. It's used just like the Ropel in that you'll spray the wood you want to protect. In most cases Pest Rid will last 2-4 weeks and they'll avoid the treated area. But it's important to understand if you're not around the log cabin more than once a month, there is a chance that either the Ropel or the Pest Rid will wear out and more damage will be done. This is when 4-The-Birds becomes the only option because it will last 3-6 months no problem.
