Unfortunately there isn't a magic spray that keeps all creatures away from your garden harvest, but there are a few things you can do to minimize the damage and ensure you'll enjoy most of your fruits and veggies without bites in them.
In today's blog we'll cover how to prevent birds from pecking your peaches and how to stop squirrels from stealing your tomatoes, as well as tips for keeping a common garden pest, caterpillars, from eating your garden goodies from the inside out.
Netting for fruit trees
Bird netting is one of the easiest ways to protect most of your harvest from birds and squirrels, and it works on deer, too.
If you're using it on a fruit tree, you can drape a large piece over the top of the tree and loosely secure it at the base of the branches using these clips, or you can buy a roll of it and wrap it around the canopy.

and its polypropylene is UV treated to be long lasting.

Netting for gardens
Drape netting over garden plants to protect your tomatoes or other veggies, or build a structure like the ones pictured below to also keep out squirrels, rabbits, and deer. The added benefit of structures like these is that they can be used with insect netting to protect against beetles and moths (caterpillars and "borers") or with row cover fabric to protect plants during cool weather. You can even integrate micro-irrigation. You can easily secure the netting or irrigation to any structure using these handy dandy clips.

and you can expand it with items found at Lowe's/Home Depot.

features a solar-powered moving head, which looks more
realistic to prey animals, like small birds and squirrels.

Motion activated sprinklers

Sprays for deer and rabbits
As I mentioned earlier, there is no magic spray to keep all critters away from your garden goodies, but there are a few sprays that can help with specific pests.
Liquid Fence is a highly effective spray that uses scent to repel deer and rabbits for several weeks. It's non-toxic, but DO NOT get it on your hands.
|It's rotten eggs and garlic, y'all, but once it's dried |
in the garden you won't notice the smell.
Funny story: I once ruined a favorite pairs of gloves when I accidentally came into contact with a leaking bottle at work. This stuff is made of rotten eggs and garlic, y'all. For an entire day I thought my coworkers were passing gas around me, only to realize later it was me and my smelly gloves!
I recommend wearing disposable gloves and mask when you apply it, not because it's dangerous, but because it's stinky and the smell lingers on skin and in your nostrils. Once it has dried in the garden you won't even notice the smell.
Liquid Fence is available in a ready-to-spray gallon, concentrate (best value!), or granules, however, the granules don't seem to work as well, since they're applied around plants, not directly on them. The Liquid Fence company also makes snake repellent. (Snakes aren't really garden pests, but not everyone enjoys their company, so some people might consider them a pest.)

If you live in Texas, you may be able to get a great price on a smaller bottle of ready-to-spray Liquid Fence Deer & Rabbit Repellent or the Snake Repellent at your neighborhood HEB.
Sprays for caterpillars and borers
Caterpillars are a huge problem for gardeners. There are many types, known by various names, each one affecting different plants. Caterpillars eat holes through cabbages (cabbage worms), make tomato plants disappear virtually overnight (tomato horn worm), mow down pepper plants and poke holes in potatoes (cutworms), dig into squash stems (squash vine borers), and destroy peach trees and their fruit (peach tree borers). These pests all have one thing in common. They're all moth larvae (caterpillars) and they're all susceptible to a naturally occurring bacteria called Bacillus thuringiensis (commonly known and sold as Bt or Thuricide). It's their "kryptonite".
You can spray Bt on plants when you see caterpillars, or use it on peaches/plums/apricots/etc. during blooming, to prevent moths from laying eggs inside the developing fruits. Add a tiny amount of molasses to the mix to help the bacteria live longer on plant leaves.
As you may know, I'm a beekeeper, so on the rare occasion that I use any sort of insecticide, it's important to me that it's natural, and that it's safe for bees.
In the case of peaches/plums/etc., many caterpillar pests hatch out between the branches before the trees flower or leaf out, and you can kill many of these by using what we horticulturists call "dormant oil spray" while the trees are still in their dormant (not actively growing) stage.
My favorite dormant oil sprays are Medina Orange Oil (which has many other garden uses, detailed in this blog) and Garden Safe Neem Oil (also known as "Fungicide 3" because it kills insects, mites, and fungi on plants). These are both natural and bee-safe when used correctly.
|Dormant oil spray is just one of Medina Orange Oil's MANY uses. |
More uses for orange oil listed here in my blog.

which also works as an insecticide and miticide.
|The Ortho Dial N Spray hose end sprayer is inexpensive and can be used to |
apply any liquid fertilizers or sprays. It has an adjustable dial that does all
the measuring for you. It's "goof proof."
As with any pesticide, even natural ones, I recommend spraying in the evening, when many of the day-flying pollinators, like honeybees and butterflies are least active. I use the Ortho Dial N Spray hose end sprayer to apply all sorts of liquids in my garden. I like it because it has an adjustable dial that does all the measuring for you. You just pour in the fertilizer/pest liquid, set the dial, and attach it to the hose, and it sprays out a perfectly pre-mixed solution. The sprayer just takes out a little of the spray concentrate at a time, so the liquid inside the sprayer bottle stays at full strength, and anything leftover can be poured right back into its original bottle.
If you're interested in learning more about bugs in the garden (both beneficials and pests), Howard Garrett's Texas Bug Book: The Good, The Bad, and The Ugly is an excellent resource, loaded with color photos and information about life cycles, pest control, etc. It's applicable for gardeners outside of Texas, too. I frequently refer to it while teaching my gardening workshops.
