However, by providing them an easy to find water source (like a dog bowl) temporarily while trying to exterminate them, this will help you remove their motivation to chew through the pipes to get water. This is especially important if you're using poison to kill the rodents, because poison dehydrates them.
Provide rodents an alternative water source.
As long as the rodents are living in your space, they need water. If you temporarily provide a water source that they can use while you are working to exterminate them, they won't have to resort to chewing on your pipes to get to the water.
Fill small holes with steel wool. Put caulk around the steel wool to keep it in place or use spray foam. Use lath screen or metal, cement, hardware cloth, or metal sheeting to fix larger holes. Cut material to fit around pipes.
Seal Up Cracks and Openings
You can seal up or block off openings in a few ways. One option is to stuff steel wool into cracks. You can also fill openings with caulk to keep the mice out.
You can purchase mesh wire made to block the drain pipes from wildlife entering at hardware stores or if you mean on the outside of the pipe a little separation between the structure and the pipes would hamper their ability to climb on the outside...
Due to their body shape, mice are capable of fitting through holes much smaller than appear likely. Mice may also enter the home through gaps in windows or ceilings, as well as through sewer lines. If drainage pipes are not properly sealed, mice may enter homes through sink or bathtub drains.
Baking Soda and Salt Barrier. Sprinkle a mixture of baking soda and salt around your drain openings. This abrasive barrier can deter bugs from crawling up the drainpipes. Reapply the mixture periodically to maintain its effectiveness.
Dangers of Mice
There is a small risk that they can pass it to you and your family members if they: Bite you. Bring ticks, fleas, and mites into your home. Contaminate your food and water with their droppings, saliva, and pee.
Steel wool - Mice are known to be able to chew through almost anything, especially if they think food is on the other side. However, one thing they can't chew through is steel wool. Fill any holes in your home with this material - air vents, kitchen cupboards, etc.
Spray foam insulation will not cause any harm to your pipes. While the spray foam is created through a chemical reaction that generates heat, neither the reaction nor the heat harms the pipes. Depending on where a pipe is located, we may spray around the pipe or directly against it.
The best sealant to keep rodents out is silicone sealant, such as silicone caulk. Silicone sealant is strong enough to combat mice teeth. But it's important to note that silicone caulk is dangerous to kids and pets if ingested. So, you'll want to keep kids and pets away when sealing your home from mice.
Steel wool, copper mesh, and expanding foam are all good options for sealing gaps around pipes. These materials are sturdy and can withstand the gnawing and clawing of mice. When using steel wool, it is important to ensure that all gaps are completely filled, as mice can easily squeeze through even small openings.
Essential oils that may be helpful in repelling rats and mice include peppermint oil, lemon oil, citronella oil, and eucalyptus oil. You can make an essential oil spray by mixing 2 teaspoons of oil with 1 cup of water or rubbing alcohol in a spray bottle. Then spray it anywhere you see traces of rodents.
Toothpaste may emit that peppermint scent that confuses mice and masks their pheromones. Plus, it's also poisonous to mice if eaten, which is why many homeowners mix it with sugar as a bait that kills mice.

This is especially important if you're using poison to kill the rodents, because poison dehydrates them.
Install a 12-inch-square piece of aluminum flashing or galvanized metal around conduit pipe to prevent rodents from climbing. Caulk gap around pipe if opening is larger than ¼ inch.
Clean drains
Usually, it's enough to run some hot water down the drain, then remove the protective cap and scrub the inside with a pipe brush.
"They typically enter homes between October and February looking for food, water and shelter from the cold." Orkin crunched numbers and ranked the top 50 most rodent-infested cities. They used the number of new rodent treatments, both commercial and residential, from fall 2022 through summer 2023.
The cost of rodent damage
These vermin can cause costly damage to pipes that need repaired. In severe cases they may cause water damage to your home. When damage is slow, a small amount of water will continuously seep in spaces within the walls. This can cause a buildup of toxic mold.
Grapes, raisins, rhubarb and walnuts are poisonous to mice and lettuce can cause them to have diarrhoea. Wild mice find food by foraging and so a portion of daily food that is provided for pet mice should be scattered in a cage to encourage this foraging behaviour.
