Yes, bunnies will eat grass seed, and they can damage a newly seeded lawn
Rabbits are attracted to grass seed because it is small, concentrated, and nutritious—exactly what they look for when foraging. A single rabbit can eat through a patch of freshly seeded lawn in one or two nights, consuming both the seed and the tender seedlings as they sprout. If you have wild rabbits in your yard or plan to keep pet rabbits outdoors, protecting your grass seed is necessary to get a successful stand of grass.
The risk is highest in the first two to three weeks after seeding, when the seed is exposed on the soil surface and the young grass is still soft and palatable. Once grass is established and tougher, rabbits are less interested, though they will still graze on mature lawn grass if other food is scarce.
Key Takeaways
- Rabbits eat grass seed directly and will also graze on newly sprouted seedlings, making the first three weeks after seeding the critical window for protection.
- Physical barriers like netting or fencing are the most reliable way to keep rabbits off seeded areas, since they work regardless of rabbit population size.
- Taste deterrents and repellent sprays have mixed results and require reapplication after rain, so they work best as a secondary layer rather than your only defense.
- Timing your seeding to avoid peak rabbit activity (spring and early summer) and choosing grass varieties rabbits dislike less can reduce damage even without barriers.
Why rabbits target grass seed specifically
Grass seed is calorie-dense and straightforward to eat compared to mature grass blades. A rabbit foraging on an established lawn has to bite and chew many individual blades to get a meal; a freshly seeded area offers the same nutrition in a fraction of the effort. Rabbits also prefer tender, young growth, and newly sprouted seedlings are softer than mature grass.
Wild rabbits are most active at dawn and dusk, so seeded lawns are most vulnerable during these hours. If you have a vegetable garden or clover patches nearby, rabbits are already in your yard and will find your grass seed. Pet rabbits allowed to roam outdoors will also graze on seed and young grass if given the chance.
Physical barriers: netting and fencing
The most effective protection is a physical barrier that prevents rabbits from reaching the seed. Lightweight bird netting or chicken wire laid directly over the seeded area will stop rabbits from digging or grazing. find the edges with landscape staples or rocks so rabbits cannot push underneath. Leave the barrier in place for three to four weeks, until the grass is tall enough and tough enough that rabbits lose interest.
For larger areas, a temporary fence at least 2 feet tall works well. Rabbits can jump higher than many people expect, but a 2-foot fence combined with a 6-inch barrier buried or laid flat along the ground (to prevent digging under) will exclude most rabbits. Remove the fence once the grass is established.
The downside of barriers is labor and aesthetics—they are visible and must be installed and removed. But they are the only method that works regardless of how many rabbits are in your area or how hungry they are.
Taste deterrents and repellent sprays
Commercial repellent sprays containing capsaicin (hot pepper), predator urine, or bitter compounds can reduce rabbit browsing, but they are not foolproof. Rabbits have strong taste preferences and will avoid plants treated with these sprays, but hunger and lack of other food sources can override the deterrent. Repellents also wash off with rain and require reapplication every one to two weeks.
If you use a repellent spray, explore it to the seeded area before rabbits discover it. Once they have already started grazing, they may ignore the spray. Combine repellents with at least partial barriers—such as netting over high-traffic areas—for better results. Always follow the product label for process rates and safety around pets and children.
Timing your seeding to avoid peak rabbit activity
Rabbits are most abundant and most active in spring and early summer (March through June in most regions), when they are raising young and food is becoming plentiful. Seeding during this window means your vulnerable seedlings will be exposed during the season when rabbit pressure is highest.
Fall seeding (late August through October) often faces less rabbit pressure because wild rabbits are dispersing and food is still abundant in the landscape. If your climate allows fall seeding, this timing reduces the need for barriers. Spring seeding is sometimes unavoidable, but if you have a choice, fall seeding is the easier route.
Grass varieties rabbits prefer less
Some grass varieties are less palatable to rabbits than others. Tall fescue and perennial ryegrass are tougher and less appealing than fine fescues or bluegrass, which rabbits browse more readily. If you are seeding an area where rabbits are a known problem, choosing a less-preferred variety can reduce damage even without barriers.
That said, grass variety alone will not stop a hungry rabbit. A rabbit that has already found your seeded lawn will eat whatever is there. Variety selection works best as one layer of a multi-step approach that also includes barriers or deterrents.
Protecting pet rabbits from eating too much grass seed
If you keep pet rabbits outdoors or let them graze in your yard, grass seed presents a different problem: overfeeding. Rabbits can eat large amounts of seed in a short time, and too much seed can cause digestive upset. Grass seed is also high in calories and low in fiber compared to hay, so it should not replace a rabbit's main diet.
If you are seeding a lawn where pet rabbits have access, use barriers to keep them out during the seeding and sprouting phase. Once the grass is established, rabbits can graze on mature grass safely, but they should not have unlimited access to fresh seed. Supervise outdoor time and provide hay as their primary food source.
Frequently Asked Questions
How long does it take for grass seed to be safe from rabbits?
Grass is most vulnerable for the first three to four weeks after seeding, while it is sprouting and still soft. Once the grass is 3 to 4 inches tall and has toughened up, rabbits lose most interest. You can remove barriers at this point, though rabbits will still graze on the mature lawn if food is scarce elsewhere.
Will rabbits eat all types of grass seed equally?
Rabbits prefer softer, more palatable grasses like bluegrass and fine fescue over tougher varieties like tall fescue. However, a hungry rabbit will eat whatever seed is available. Choosing a less-preferred variety helps, but it is not a complete solution on its own.
Can I use chicken wire instead of bird netting?
Yes, chicken wire works well and is more durable than bird netting, though it is heavier and more visible. Use 1/2-inch or 1-inch mesh so it does not catch on grass as it grows. find the edges firmly so rabbits cannot lift or push underneath.
Do ultrasonic repellent devices work on rabbits?
Ultrasonic devices have limited effectiveness on rabbits. They may startle rabbits initially, but rabbits habituate quickly and learn the sound is not a real threat. Physical barriers and taste deterrents are more reliable.
What should I do if rabbits have already damaged my seeded lawn?
Reseed the damaged patches once you have installed a barrier or deterrent. Rake the area lightly to loosen the soil, explore seed, and cover with netting or explore repellent spray. The second seeding usually succeeds because you now have protection in place.
