Seal Rodent Entry Points

Rodent Entry-point Repair & Sealing Services, Portland Oregon

Sealing rodent entry points, also known as “rodent exclusion,” is a specialty service. Other home service contractors may not realize that minor gaps in construction could leave your home totally vulnerable to rodents. A pest exclusion professional will identify rodent entry points and use metal materials to permanently seal holes & gaps in construction to prevent future rodent & wildlife incursions into the home.

How To Seal Rodent Entry Points

Portland has a scary rat problem.

Luckily, rat entry points into the home are often obvious to a trained pest control professional. Damaged foundation vents, chewed dormer corners, and gaps along the gutters or mud sill are the most common areas for rats to enter.

If sealed well, you can prevent rodent infestations.

Carefully inspect these areas and anywhere construction materials meet. A gap between the top edge of your concrete foundation & the mud sill, damaged foundation vents, and burrows underground become entry point for rats and mice.

To seal these difficult areas, use weatherproof, metal materials, and secure with the proper fasteners.

  • Consider if your exclusion will affect moisure & water,
  • Use stainless steel exclusion fabric or copper mesh for small gaps,
  • Only use spray foam to glue steel or copper mesh in place,
  • Use metal flashing when possible for large gaps,
  • Use heavy gauge steel mesh if you can’t use solid metal,
  • Special tools may be required,
  • **Be aware, if any gap greater than a quarter inch is left, rodents will likely re-enter over time.

How To Get Rid of Rat Burrows 

Increasingly Portland rat control companies are finding rat burrow holes in yards, parking strips, along driveways and crawlspaces. Once established, these smooth, softball sized rat holes are likely to reopen periodically even when filled.

Norway rats are burrowing animals, whose burrow systems extend from the sewers, under slabs, rocks, tree roots and other unknown habitat niches underground. Once dug out and excavated, the burrows remain open until natural soil erosion, settling or some other process closes them.

Use small diameter pea gravel from the hardware store to fill any burrow openings you find outside. Use a rod or stick to pack a small amount at a time as deeply into the burrow as possible. Keep more pea gravel on hand in case it reopens and you need to get rid of the rat burrow again. Anticipate intermittent periods of no activity, but monitor regularly and fill as needed to keep rat burrows closed for good.

How To Seal Mouse Entry Points 

For the best mouse control, any obvious entry points should be sealed. Unlike rat entry points however, mouse entry points are often undetectable even to an experienced rodent exterminator. Tiny burrows under the foundation, gaps under garage door seals, between framing, and along plumbing pipes or conduits create small entry points for mice in the home. As always, use Integrated Pest Management for mice to relieve inward mouse pressure towards the home.

Inspect along your foundation and gutter line for any gaps. Preventative home maintenance including regular roof inspections and repairs is the best way to seal mouse entry points. Clean gutters regularly to prevent separation along the fascia and roof board. Once certain areas begin to separate and open, they can be difficult to seal off from rodents without extensive home repairs.

If you’ve had mouse or rat exclusion and are still having issues, or are interested in rodent hole repair services, give us a call. We’ll determine the root cause of rodent issues, seal any rodent entry points we can & get your home rodent free.

Rodent Exclusion Facts & Tips:

  • Rats have razor sharp teeth with the ability to chew through nearly any material including solid wood, concrete, heavily compacted dirt, and sometimes even softer metals like aluminum.
  • Always use Integrated Pest Management for rodents to control rats and mice naturally.
  • Some homes due to old construction or subterranean burrow entry into the crawlspace, are extremely diffuclt to seal permanently from rodents entering.
  • If you’re getting your roof replaced, you may need to specify to roofers that you’ll need rodents sealed out, in addition to water. Have them use metal materials for any vent covers installed.
  • Inspect foundation vents after having AC or cable installed and have any damaged vents repaird right away.
  • Don’t bother plugging up rodent holes or gaps along the interior of the home. To effectively seal rodent entry points, your goal must be to seal them from breaching the exterior “shell” of your home.

I strongly recommend Keith for all your pest control needs. He's very responsive and good at explaining what he's going to do. We had a yellowjacket nest right in our front yard by the sidewalk—our mailman had decided he couldn't deliver mail anymore! Was really happy with how Keith dealt with the nest, and he even came by a week later for a second treatment after we saw a few survivors. I chose Keith because he is IPM certified, and I'm very happy with my choice.

Keith was so nice, professional and best of all cares deeply about the environment and avoiding toxic chemicals. The treatment was quick effective and did the trick within days. I have already recommended him to several friends and will definitely call again! Thanks Keith!

We had a great experience with Keith at Pest & Pollinator. We needed a raccoon latrine removed, and Keith made the whole process straightforward from start to finish. He was easy to communicate with over text, quick to coordinate, and managed to fit us into his schedule. He clearly explained his process, and took the time to answer our questions. He thoroughly removed the latrine and even applied a free deterrent to keep them from returning. The issue is completely resolved and the raccoons haven't been back. Keith is reliable, professional, and provides excellent service. I’d highly recommend him for any pest or wildlife needs.

So happy we found Keith and his integrated approach to dealing with pests. We’d been dealing with sugar ants for weeks and wanted them gone – but didn’t want to kill all the other creepy crawlers because we’re trying to get our Backyard Habitat Certification. The good news: Keith’s company is approved to work with yards going through the program. Keith speaks fluent ant – understanding their behaviors and possessing the uncanny ability to quickly locate their colonies. We really appreciated how thorough he was – explaining what he was doing every step of the way. Since Keith came out, we’ve been ant free ever since.

We had a huge inground bee nest with over 200 plus bees right next to our pool. We were having a party and needed to have them gone asap! Keith came in super short notice had them all gone within a half an hour! Super easy to work with and great guy!

Keith did is incredibly thorough and conscientious. He took his time listening to issues and assessing the situation before suggesting a course of action. He properly set expectations by making us aware of the lead time necessary to see meaningful results and he was spot on. Moreover, he made it clear our level of ant traffic would probably require a second pass in a few weeks and that he would come back out for free if the problem wasn't 100% resolved. Sure enough, we had a one particularly resilient corner of our house after a few weeks. When Keith proactively circled back, we gave him the update and he was back at our house a couple of days later at no charge. We are ant free and very satisfied. (Thanks Keith!)

I got a good assessment of the extent of a raccoon presence, confirming it didn't extend to crawl space, and was able to evict and seal. They're still around, great, but no crash pad at my house!

Pest & Pollinator is great! Exterminator Keith is unlike any exterminator that I have ever met and he helped me with a developing carpenter ant issue. Keith is very professional, tactful and discriminating, and cares about the environment. He didn't just trample through my house blasting poison everywhere like every other exterminator I've ever met. Keith listened to my goals like not stressing or harming my dogs during the process, not putting toxic stuff in my home, and definitely not killing insects indiscriminately because I recognize how important it is to protect declining insect populations. He spent time carefully inspecting my house and yard (even pulled out a ladder and looked at my roof), taught me about carpenter ant behavior and environmental modifications that deter without poison, and showed me things about my house that I never noticed. I forgot what he put down to stop my carpenter ant problem, but he used very little and very judiciously. Within two days, the ants were gone. I am always so grossed out by extermination companies that brag about killing animal and insects. I really felt that Keith respects and cares for animal like and the environment while also recognizing that we sometimes need insects to not harm us. I can't recommend Pest & Pollinator enough.

Keith did an incredible job helping us manage problematic ants on our property. Keith was quick to meet with us and provided an explanation the entire way about his process. He successfully dealt with the ants using products and measures that were safe for both humans and animals. Approaching 2 months ant free! Would highly recommend Keith and Pest & Pollinator!!

Keith is the best. He thoughtfully and thoroughly took care to diagnose the issue and designed a treatment that fit the situation. Pest and Pollinator will not try to upsell or bind you in a contract like its competitors. Keith also understood and respected why I wanted to keep the spiders around the property. That meant a lot. Overall, Pest and Pollinator is amazing. Choose them.
