How to Seal Squirrel Entry Points 
Sealing squirrel entry points is a good idea as soon as you spot them. Check for flour tracks and then attach a wire mesh barrier to the framing of the opening. Wait until the squirrel leaves before removing the barrier. If the animal remains, you may need to repeat the process. However, if you are confident that your property is squirrel-free, sealing the entry point will stop future problems. And in the meantime, you will be safe from their attacks.
One-Way-Door
A one-way door is a squirrel-proof enclosure made with spring-loaded doors that close behind the squirrel. Install one of these doors in your home to keep squirrels out, but make sure to use them on a secure structure. Other squirrel-proofing options include installing steel mesh to cover the entry point, or cutting back trees to limit their access. Properly installed chimney caps also prevent squirrels from entering a home.
To properly seal a squirrel-proof entry point, it is important to identify and close the entrances as soon as possible. If you spot a squirrel in your home, you can use talcum powder or flour to discourage it from re-entering. If you can’t seal the entrances, you can install a wire mesh barrier on the other side of the entry. It is important to wait for the animal to leave before attempting to seal the entry points.
If you’ve tried a variety of methods to eliminate squirrels from your home, one-way-doors are the most effective. These devices are similar to a wire trap, but open on both ends and feature flanges or wings that seal the entrances. Once the squirrels leave the enclosure, they cannot return to it. You’ll still need other wildlife removal strategies, since one-way doors don’t provide adequate protection against various entry points and internal food sources.
Ditrac Ground Squirrel Bait
Ditrac Ground Squirrel Baited is a non-restricted use rodenticide made especially for California Ground Squirrels. It works by baiting the squirrels with an attractive food source, sealing their entry points and eliminating them from your property. Ditrac contains 0.005 percent active ingredient and is sold in a 12 pound pail or 50 pound bag. Its tamper-resistant bait station is a must for effective use. It contains 0.005 percent diphacinone, which will compete with the squirrels’ natural food source and eliminate them from your property.
When it comes to baiting, timing is critical. It is most effective if bait is applied when the entire population of ground squirrels is active. Baiting does not work when part of the population is hibernating. Females usually emerge about one to two weeks after the males, and baiting is ineffective if it occurs when the females are still hibernating. Also, baiting is not effective if applied too late in the gestation period or shortly after the young are born. Baits are not effective when applied during the hibernation period or during early gestation, as females are rarely above ground during this time.
If you have an infestation of ground squirrels, consider sealing them off with repellents. Repellants can minimize the smell of dead rodents. Sealing entrance points can also prevent squirrels from entering the house. When used in conjunction with other repellents, Ditrac Ground Squirrel Bait is a safe, effective and long-lasting way to control squirrels.
Ditrac Flying Squirrel Bait
To get rid of flying squirrels, you need to find their entry points. For this, you can use a trap or poison. Poisons cause internal bleeding and can kill animals that are not targeted, like domestic cats. Better yet, you can simply exclude the flying squirrels and block their entrance. Luckily, Ditrac Flying Squirrel Bait seals entry points in a single application.
Ditrac Ground Squirrel Bait is a bait specifically designed to control California Ground Squirrels. Most rodent control baits will not work against other types of squirrels, including common ground squirrels. For effective trapping, make sure to use one-way door devices or squirrel exclusion barriers. The door is closed when the flying squirrel exits, but the other squirrels will still be able to escape.
Flying squirrels are nocturnal. They enter attics in search of food, warmth, and a place to raise their young. They can enter through holes in the eaves, soffits, and facia board. They can also chew the insulation in walls and spread foul odors. The best way to prevent flying squirrels from getting into your home is to seal all entry points.
