Question
Hello, I live in Southern Ontario something is eating my strawberries. Not rabbits as garden is fenced off. Eating only the ripe ones.

My veggie garden which is separate garden and also fenced. The leaves of the pea plants and pepper plants are being eaten. I cannot find anything on the leaves which are the main part of plant being eaten. Garden is fenced off.

Answer
Louanne, without you physically seeing the pest, it is very hard to determine what it may be. It could be a variety of pests including beetles, slugs, or even 4-legged pests such as deer, rabbits, or groundhogs. Most animals will enter under the fencing. Before treating the problem, you definitely need to identify the source.

If they are being attacked by insects, you can treat the plants with a product called pyrethrum. This is an organic insecticide derived from the chrysanthemum flower. It is non-toxic to humans and pets but highly effective against most garden insects.

If the problem is an animal, the solution is a little more complicated.

You have four options at this point.  You can cover the plants with row covers, attempt to trap the animal, use an animal repellent, or as a last resort use poison to eradicate it.

Row covers, also sold under the brand name reemay, is probably the  most effective option, but it also is the most impractical depending on the size of your garden. It also can be unsightly. However, it may dissuade the pests for a few days to go elsewhere to find their next meal. By the way, row covers are also very effective against insects. The material is made from a light-weight fleece, and looks similar to a sheer curtain. It lets light and water in, but keeps pest out. It is very light and will not weigh down the plants.

Trapping is relatively easy. I recommend purchasing a commercial trap sized for the animals suspected above. Havahart makes a very reliable one which can be purchased at most garden centers. Bait the trap with carrots, lettuce, and peanut butter. Once caught, you抣l need to relocate the animal to a location at least one mile away.  The only problem with this option is once again your location. There are most likely hundreds of critters in your area. But the odds are only a few are venturing into your yard. Traps can be highly effective, but it will be a constant effort.

There are many chemical repellents sold in local nurseries such as Ropel. Although most are effective, they need to be reapplied after a rain. Other organic repellents which have proved effective are cayenne pepper, blood meal, coyote urine (also available at most garden centers), and garlic spray. Garlic is extremely effective at repelling animals and insects. Many gardeners plant it liberally throughout their garden for this very reason. Just be sure to never plant it near beans or peas as it tend to stunt their growth. Marigolds, due to their undesirable scent and taste, are another option. They are especially effective against rabbits.

Finally, and the least desirable alternative, is poisoning. Most garden centers carry various poisons which can be used. Keep in mind, however, that they are also toxic to pets and humans, and should never be placed directly in the garden.

In summary, try the pyrethrum first. If your problem turns out to be an animal, repellents are probably the most practical alternative you have at this point. Next year, I would plant plenty of garlic and marigolds to deter the pest. In the meantime, I would try the trapping to see how many animals are actually visiting each night. You may be surprised to find that only a few are causing your problems.

I hope this helps. Good luck, and please write again if I can ever be of assistance.

Regards,

Mike
