San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.

Rats are clever because they can detect the holes, even the tiniest ones in pipes. As a result, it is easy for them to get to the divider and use it as a safe house.

Sewers are likewise the ideal entryway for these rats to get inside the house. This is why the rat-proofing plan has to come up when you want to build a home or renovate a house.
Traps can likewise be set since it is by a long shot, the best method to catch rats - as rats can run quickly and effectively escape, it might be difficult for humans to find them utilizing their uncovered hands. Typically, catching is perfect for businesses working with large spaces and holes that might not be distinguishable.
Another modification is to try putting away foods appropriately inside containers that are rat-proof. Garbage should be properly sealed and shut because it may attract rats. When you store garbage in a can, ensure that the cover is tight enough.
Keeping up regular maintenance of the building won't allow any breaks and holes to appear. Great fixes are essential because rats can effectively fit a coin size gap and eat the foods inside your home.
