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.
San Diego Rat Control Tip of The Week
City Subways And The Presence Of Rats
Rats, like pigeons, badgers, and foxes thrive in urban environments, even moving to these places. Cities are full of garbage dumps, abandoned lands, and sewers that can provide a cozy burrow for rats to live in and raise their families. Human beings have provided the perfect conditions for the well-being of this species.
Sewers And Rats
Sewers can provide everything needed for an exponential multiplication of rodents. The problem is that the more rats there are, the more they need food, so to get it they will be severely aggressive towards each other. This aggressiveness and the search for new food sources can cause serious damage to the city.
Rats Are The Real Infection
These rodents are known for carrying bacteria that cause infectious diseases leading humans to death. Something similar occurs with rats when they spread through sewers, subways, garbage dumps, and train tracks.
Rats survive thanks to the mountains of garbage in the city and play a vital role in reducing this waste. However, wiring or holes and infrastructure problems can be just some of the catastrophic consequences for the city's subway system.
Super-rats
Humans love junk food and in big cities, high-calorie garbage has given the rats that eat it the energy they need to grow exorbitantly even creating resistance to some rat poisons.
The well-being of citizens begins with professional pest control combined with a mind-set of not throwing garbage into the environment. Briefly, if there is neither food nor garbage, there are no rats. The fewer rats there are in places like the subway, the fewer rats will be able to reach homes. The more we take care of the city, the fewer health problems or economic damage there will be.
