Yes, squirrels will eat grass seed, and they are one of the most persistent lawn pests you'll face
Squirrels eat grass seed because it is calorie-dense, straightforward to find, and requires no work to crack open like a nut does. A single squirrel can consume or scatter several pounds of seed in a week, especially in spring and fall when they are building fat reserves. They dig shallow holes, bury seeds they don't eat when ready, and often forget where they buried them—which means you lose the seed and get nothing to show for it.
The damage is not just the seed itself. Squirrels dig up freshly seeded areas, leaving bare patches and small mounds of soil. They also dig under existing grass to bury seeds, which disrupts root systems and creates an uneven lawn. Once squirrels discover your lawn is a food source, they return repeatedly until the seed is gone or you change the conditions that attract them.
Key Takeaways
- Squirrels prefer sunflower seeds and safflower seeds over grass seed, so choosing the right seed type reduces but does not eliminate the problem.
- Physical barriers like netting or fencing are the most reliable way to stop squirrels from reaching seed, though they must stay in place until grass germinates.
- Taste deterrents and capsaicin-based repellents work on some squirrels but not all, and rain washes them away within days.
- Timing your seeding to avoid squirrel activity seasons—late fall or winter in most regions—lowers the chance of heavy damage.
- Removing food sources like fallen nuts, pet food, and bird seed reduces the squirrel population in your yard and makes grass seed less attractive by comparison.
Why squirrels target newly seeded lawns
Squirrels are drawn to grass seed because it sits on or just below the soil surface where they can reach it easily. Unlike acorns or hickory nuts, grass seed does not require the strength to crack open. A squirrel can eat dozens of seeds in minutes, and the high fat content makes the effort worthwhile.
Newly seeded areas are especially vulnerable because the seed is concentrated in one place and the soil is loose and straightforward to dig. Squirrels also recognize that freshly disturbed soil often means food—they use the same instinct when searching for buried nuts in fall. Once a squirrel finds your seeded lawn, it will return daily until the seed germinates or is consumed.
Physical barriers that actually stop squirrels
The most effective defense is a physical barrier that prevents squirrels from reaching the seed. Bird netting or hardware cloth (a wire mesh with half-inch openings) laid directly over the seeded area works because squirrels cannot dig through it. find the edges with landscape staples or rocks so squirrels cannot lift or roll it up. Leave the barrier in place until grass is two to three inches tall and the seedlings have rooted—usually two to four weeks depending on grass type and temperature.
The downside is that netting or cloth blocks water and light slightly, though not enough to stop germination if you use a loose weave. You will also need to water from above or remove the barrier to water, since water penetrates slowly through the mesh. This method works best on small seeded areas—a large lawn becomes impractical to cover.
A second option is a temporary low fence around the seeded area, at least two feet tall. Squirrels can jump higher than two feet, but they are less likely to attempt it if they cannot see a clear landing spot on the other side. Combine a low fence with netting on top for maximum protection on valuable areas.
Taste deterrents and repellent sprays
Capsaicin-based repellents (the compound that makes hot peppers hot) can discourage squirrels from eating treated seed. Products like Capsaicin Seed Coat or similar formulations are applied directly to the seed before spreading. The seed tastes unpleasant to squirrels but does not harm them or the grass.
The limitation is that capsaicin washes off with rain or watering, so you need to reapply every week or after heavy rain. Some squirrels also become accustomed to the taste over time, especially if other food sources are scarce. Taste deterrents work best as one part of a larger strategy—they slow squirrels down but rarely stop them completely.
Liquid repellent sprays applied to the lawn after seeding have mixed results. Products containing predator urine or garlic smell unpleasant to squirrels, but the smell fades within days and rain removes them faster. These sprays are worth trying on small areas, but do not rely on them as your only defense.
Timing your seeding to avoid peak squirrel activity
Squirrels are most active and hungry in spring (March through May) and fall (August through October) when they are building fat reserves for winter. Seeding during these windows means squirrels are most likely to find and eat your seed. If you have the option, seed in late fall (November or December in most regions) or winter when squirrel activity drops and they are less focused on foraging.
Winter seeding works because seed lies dormant in cold soil and germinates in spring when squirrels are busy with other food sources and raising young. The seed also has time to establish roots before summer heat arrives. Check your local frost date and seed type to confirm winter seeding is appropriate for your grass variety.
If you must seed in spring or fall, combine timing with physical barriers or deterrents for the best outcome. Even a two-week delay until after the peak of squirrel activity can reduce damage significantly.
Removing food sources that attract squirrels to your yard
Squirrels are less interested in grass seed if other food is scarce. Remove fallen nuts, acorns, and seeds from under trees and shrubs. Rake regularly in fall to clear debris that squirrels use as a food cache. If you feed birds, use a squirrel-proof feeder or place feeders far from the lawn you are seeding—squirrels will focus on the easier bird seed rather than digging for grass seed.
Pet food left outside is another major attractant. Feed pets indoors or remove uneaten food within an hour. Compost piles that contain nuts, seeds, or fruit scraps also draw squirrels. If you compost, use a sealed bin rather than an open pile.
Reducing the squirrel population in your yard takes time, but it makes grass seed less attractive by comparison. A yard with few squirrels and no obvious food sources will see less seed damage than one where squirrels are already established and fed regularly.
Seed type matters—some seeds squirrels prefer over others
Squirrels have preferences, though they will eat most grass seeds if hungry enough. They strongly prefer sunflower seeds and safflower seeds, which are common in bird seed mixes. If you are using a standard lawn seed mix, squirrels will eat it, but they may leave it alone if bird seed or nuts are available nearby.
Switching to a seed blend that includes fescue or perennial rye (which squirrels find less palatable) can help slightly, but this is not a reliable solution on its own. The real benefit of choosing seed type is that it works alongside other methods—a less attractive seed combined with a physical barrier or deterrent is more effective than either alone.
Frequently Asked Questions
How much grass seed can one squirrel eat in a day?
A single squirrel can consume or scatter several pounds of seed over a week, depending on seed size and how hungry it is. On a freshly seeded lawn, one squirrel can damage a significant area in just a few days by digging and burying seeds rather than eating them all on the spot.
Will squirrels eat seed that has already started to grow?
Once grass seedlings are one to two inches tall and have rooted, squirrels lose interest because the effort to dig them up is not worth the reward. Grass that has germinated and begun to establish is much safer than bare seed sitting on the soil surface.
Do ultrasonic squirrel repellents work on grass seed?
Ultrasonic devices have not been shown to be reliable at stopping squirrels from eating seed. Squirrels may avoid the area temporarily, but they often return once they realize there is no real threat. Physical barriers and taste deterrents are more dependable.
Can I use poison or lethal traps to stop squirrels from eating seed?
Lethal control is legal in some areas but not others, and it is rarely practical for a lawn problem because new squirrels move in from neighboring yards. Non-lethal methods like barriers and deterrents are more effective long-term and do not require ongoing removal of dead animals.
What is the best time of year to seed if squirrels are a problem?
Late fall or winter seeding avoids peak squirrel foraging seasons and allows seed to germinate in spring when squirrels are less focused on digging. Check your local frost date and grass type to confirm this timing works for your region.
