Insecticides that are not specific to the type of pest can prove fatal to rabbits.
I have been told that it is healthy for humans who consume pest-contaminated vegetables, but it may be hazardous for your pet rabbit. In addition, organic pesticides formulated from natural oils and plant materials can cause cancer in lab tests on mice and rats. This risk is theoretical only; there has been no real-life evidence showing a link between pesticide use and cancer in people or pets. Since this information did not change my position significantly, I did a little more research on the subject for you to consider:
One of the most widely used forms of flea control uses pyrethrins from chrysanthemums sprayed onto carpets and other surfaces where animals or people spend a lot of time.
The EPA is concerned that this organism will eventually become resistant to any pesticide used against it, causing untold misery and possibly death among both pets and humans.
Animals and birds can be poisoned by eating the plants sprayed with pesticides:
There is a concern for the poisoning of animals such as cattle, horses, sheep, and wildlife if they graze on pastures recently treated with these chemicals… Cats may bring home dead or dying animals as gifts! (link)
These flea control products are also toxic to fish, birds, frogs, and aquatic invertebrates like shrimp.
Do not use pesticides indoors since their fumes often cause illness in humans. Don’t use them near food prep and eating areas and keep pets and children out of the area until it has been thoroughly aired out.
Rabbits should not be allowed to graze on plants that have been recently sprayed with pesticides. If they do, remove them from the area at once and give them fresh water (rabbits can quickly die from pesticide poisoning). But don’t panic if your rabbit eats a few leaves off your strawberries; those chemicals are not nearly as toxic as those found in dog and cat flea remedies.
The acute toxicity associated with many pesticides is related to their strong odors and tastes (which discourage an animal from consuming or tasting them) and their concentrations (often quite high), rather than their active ingredients.
If your pet lives indoors, you can avoid all pesticide exposure by not using chemicals of any sort on your plants. Otherwise, the only pesticides that are labeled for use in and around homes without endangering pets or children are boric acid (Borid) and paradichlorobenzene (PDB).
Neither has any odor or taste that would discourage rabbits from eating them. You should always follow label directions on both types of products. Use PDB crystals sparingly to reduce fumes since they do give off an unpleasant odor when first applied!
RABBITS & PESTICIDES:
Rabbits suffer no ill effects if they eat one or two leaves of a freshly sprayed plant, but some pesticides may cause minor symptoms such as drooling, vomiting, itching, or diarrhea. If your rabbit eats a large amount of pesticide, contact your veterinarian immediately.
If you are unsure whether pesticides are to blame for these symptoms, take a fresh sample of the suspect plant along so the vet can confirm the diagnosis. But don’t panic; pesticides cause few deaths among animals that eat them (similarly, humans who drink bleach rarely die).
If your pet lives indoors and you use insecticides around your home, keep him out of those areas until they have thoroughly aired out. Last but not least: never allow rabbits to graze on any type of herbicide-treated grass or lawn!
FAQS (How do I keep rabbits from eating my perennials?)
What is the best way to keep rabbits away from pesticide-treated plants?
I would recommend using natural repellents or deterrents. I like the idea of planting marigolds for this purpose, as they are easy to grow and inexpensive (Marigold Enemy). Pest animals also hate garlic; you can plant it near your veggies and other plants to keep pests away. You can also try planting strong-smelling herbs near your plants, such as lavender and rosemary, which will encourage good bugs to come and get rid of the bad ones.
Do natural pesticides work?
Yes, they do! Insecticidal soaps are a good choice for use on vegetables and fruits. You will want to use a product that is specifically labeled for use on food crops. Be sure to follow the directions, and if you find it isn’t doing the job, try another brand.
