If you live near a creek, pond or lake, you may have more trouble with wild life

Recently I was in a Silicon Valley neighborhood forum where someone asked what to do about a mouse (“or something”) in the wall of a house.  For better or worse, I have a fair amount of experience with this both personally and professionally: birds in chimneys, mice and rats in homes (inside plus in the attics, walls, crawlspaces, and heating ducts) and even a bat that got into first an attic and then into the living area itself – that last story goes with the photo from a backyard in Campbell of a townhouse I sold some years ago.

Sometimes this can be a do-it-yourself project but often it’s better if you leave it to the professionals: a good termite & pest control company is normally going to be your best bet for removing rodents and other unwanted visitors and keeping them out.

What happens if you hire someone to get rid of your mouse, rat, bat, bird or other invading animal?

Usually it’s a 3-4 visit process over 3-4 weeks to catch the house guest, then do “exclusion work”, which means finding how it got in and making sure that or any other access points are cut off, then rechecking another time or two to make sure that the problem is taken care of.  (What you do not want to do is get a dead rat or mouse stuck in your wall, so the pros will usually use traps where they can retrieve them rather than poison in the house’s attic or crawl space.)  The cost is often a few hundred dollars for this multi-visit process.

A lot of times, the rodents can get in through a torn exterior vent in either the crawl space or attic and from there go up or down the walls to get to the opposite side, so if you have the pest guys come out, expect them to need access to both the crawl space and the attic access (for most people, that means clear all the stuff off of the floor of the closet that has the opening to the crawl space and remove anything stacked up under the attic hatch).  If your duct work is loose, the truly adventurous and creative visitor may decide to see where it goes.  That actually did happen at my own house on Easter Sunday some years ago. It was noisy as the panicked creature ran along the length of the duct work under our house.  My kids were worried that it would pop out at one of the heat registers so placed books and heavy items at the access points to keep it from getting any closer.  And they dubbed our noisy athlete “the Easter Rat“.

Many termite companies have a branch that takes care of this type of work, but not all do. Thrasher Termite & Pest Control in Los Gatos  (408  354-9944) is who I suggest to my clients and who has helped us keep out intruders at our home (this is not a paid post).  I’ve been very happy with their work.  Many, but not all, termite companies have a division that handles these problems, so they are a good place to try if you have an unwelcome guest from the wild.

Pet rats – the kind you buy at the pet store – can make the most adorable friends. Pookie was our daughter’s pet and a close family member for years.

But rats in the roof, attic, crawl space, walls and landscaping are not so adorable. They wreck havoc and can cause damage to home and health. Wild rats gnaw on wood and wires, and they carry fleas that can spread disease. Bubonic plague is not an issue in Santa Clara County now, but it is in Tahoe and other areas, so it’s a risk to take seriously.

What kind of rats exist here, in The Valley of Hearts Delight?

In Silicon Valley, the predominent type of wild rat is the Roof Rat (also known as the Black Rat or Tree Rat). The Roof Rat’s eat ivy, fruit, pet food, nuts and other goodies found in neighborhoods. They are identifiable because their tail is longer than the head and body together.

A lesser seen rat in the San Jose area is the Norway Rat (also called the Wharf Rat, the Sewer Rat, or the Brown Rat). This rat has a shorter tail and is usually seen in less developed areas, creekbeds, and farm areas, which are rapidly disappearing here in the South Bay.

Recently a neighbor of ours found a dead rat in his yard, and he called The Santa Clara County Vector Control District office to come out and help him identify if there was a problem with rats getting into his home or not, and to shed light on the issue of why this critter recently appeared in his home. The officer came out and performed this service for free, enlightening my neighbor as to access points and providing a helpful brochure about rats and what attracts them.

I’d heard that Italian Cypress trees, juniper and ivy were all bad – that is, that they attracted rats. What I did not realize is how many other things do too.

Here’s a partial list of landscaping to avoid if you want to not attract rats:

• Italian Cypress Trees
• Juniper Tams
• Algerian Ivy
• Date Palm Trees
• Bamboo
• Honeysuckle
• Star Jasmine

Other rules of thumb to avoid enticing rats to your yard:

• no climbers
• low growing – not more than 10″ high
• plants providing fruit should not be used

I dislike ivy and juniper (and grew up with a Realtor mom so always heard that they were rat-friendly), so I thought I was in the clear with my own yard. Not so. I have climbers and star jasmine. We have fruit trees and usually only pick up the fallen fruit once a week. Apparently that’s all bad!!My neighbors have bamboo. Other neighbors have juniper and Italian cypress.

The Vector Control brochure makes a point that for rats to inhabit an area, they need food, water, and a home (or “harborage” as the pamphlet says). By eliminating the type of plants which provide harborage and food, we can reduce the risk of a rat invasion. After my neighbor’s experience, I think that’s a plan worth implementing!

If you live in Santa Clara County, once known as ˜The Valley of Hearts Delight, you no doubt appreciate our mild, sub-tropical climate.

Unfortunately, so do the termites.

We have two types of termites here (and other wood-destroying pests too), drywood termites and subterranean termites.

The subterranean termites, or ˜subs as they are called, can be identified by the mud tubes they build from the ground or floor up the side of a wall. As their name implies, they live underground, and build the tubes as they go. Pest Control operators will remove the tubes and treat the area, injecting chemicals underground at spaced intervals, to exterminate them.

Drywood termites, or drywoods, may live anywhere in the the home where theres wood to eat. If they are found only in one area, or perhaps two, a licensed pest control company may do a ˜local treat. The difficulty with local treatments is that drywood termites also may be lurking in places that cannot be seen, such as between the walls. For that reason, the standard recommendation is to fumigate (or ˜tent or ˜fume) the structure.

Perhaps the biggest problem with termites here in Silicon Valley, or most of California for that matter, is that they come back. A home may be tented and treated and issued a Section One Clearance (no active infestation of wood destroying pests or organisms), but theres no way to really keep the termites from coming back. The fume doesnt keep them out – it just kills the ones that were there the day the tent went on.

So how often should a homeowner have a pest control company come out and inspect for termites and other pests? A few months ago, I interviewed Janet Thrasher of Thrasher Termite and Pest Control for my Live in Los Gatos blog, asking her ˜How Often Should You Get a Termite or Pest Inspection? She said that every 2-3 years is about right, and reminded me that a good termite inspection will include areas where most homeowners dont go, such as the crawl space and the attic.

Janet and I also discussed Choosing a Termite and Pest Company. She had some great advice about that which you can read on my Live in Los Gatos blog. I would add this: there are some large, national pest control companies that do NOT go into the crawl space, so do not hire them to do this inspection! Ask when you phone the termite companies whether this is standard or not. In some areas, theyll do the crawl space but will charge extra. In San Jose, that would be a ripoff! So make sure you are getting the full inspection. In some homes, it may not be possible for the inspector to ˜do the crawl because of small spaces, ductwork in the way, or moisture under the house. And in some homes, theres so much insulation in the attic that the inspector cannot safely go there either. But generally, these areas should be able to be inspected.

Most pest or termite reports are ˜separated reports, which means they separate the findings into a couple of different categories: section 1, section 2, unknown further inspection, and information item.

Section 1 means that theres an active infestation. (Envision termites, fungus, boring beetles, dry rot, or other pests or organisms actively eating or destroying your house.) In the purchase of a house, condo, townhome, sellers will frequently pay to have the section 1 work done.

Section 2 means theres a situation that is going to cause an active infestation if you dont do something about it. This might include cellulose debris (wood chips, for instance) under the house, or water near or touching wood members (will invite dry rot and fungus). These are items that should be done. In a home sale, though, sellers usually do not pay to have section 2 work done.

Sometimes theres a hint that something might be amiss. Lets say the floor in the bathroom has a little stain near the tub or toilet. It might be nothing, but it might mean that theres been a water leak and the floor is not just discolored, but actively infested with dry rot, for instance. This might be an ˜unknown further inspection because to really see whats going on, the owner would need to authorize the pest company to remove the vinyl flooring and check the condition underneath. In some cases, pest control operators freely use the ˜unknown further inspection category simply to cover themselves, but the better companies will not overuse this classification of what theyve found.

Information items are simply that – items that the pest inspector noted that should be of interest to the homeowner even if not relevant to a pest inspection.

If its been awhile since youve had an inspection done, I would suggest doing it soon, especially since the weather is good. (Rainy days are not ideal for doing a termite inspection.) There are many fine, reputable companies in Santa Clara County, but there are also a few which have a terrible reputation among Realtors and other pest operators. You dont pay more for a good inspection! (By the way, beware the ˜free inspection as those folks often dont do the crawl space and are paid for finding things to do in your home.) My preferred company is Thrasher Termite & Pest Control in Los Gatos (contact: 408 354-9944 or email info@thrashertermite.com). I have worked with them for 15 years, and they treat my house too. There are other good ones too. If youd like a longer list of San Jose area termite companies, please call or email me and I will give you a list of reputable ones which I would trust.
