How You Can Help the Bees, Butterflies and Birds

When confronted with something eating your prized tomato plant, sometimes our first instinct is to pick up the bottle of pest spray. Oftentimes, we don't even realize that the plants we've purchased contain neonicotinoids, which are systemic (within) the plants' leaves, stems, flowers, nectar, and fruit. These 'neonics' are highly effective in killing pests, but they lack discrimination, and mounting evidence suggests they are contributing to the decline in pollinator numbers. An alternative is called IPM or Integrated Pest Management. The concept is to address pest infestations as they occur and manage pest damage on an as-needed basis, rather than chemically on a predetermined schedule.  

Cultural practices may include:

  • Is it a pest? Many of our most beautiful butterflies will use our garden or yard as a source of food, as well as caterpillars! If you can't identify the insect snacking on your plant, try contacting the Anoka County Extension Service for help with identification or go online. There are free apps that can help identify many insects, including iNaturalist, which can also help identify plants
  • Regular compost additions to maintain a healthy population of soil organisms
  • Crop rotation to avoid inadvertently helping pests thrive via monoculture
  • Companion planting to attract beneficial insects while reducing the attraction of pests
  • Using physical barriers like fine mesh netting and row covers to prevent pests from reaching crops
  • Hand removing larger pests from plants when practical, Japanese beetles are a good example. Late afternoon is a good time to find these bugs and dispose of them in soapy water.
  • Maintaining garden hygiene by removing diseased and end-of-season vegetation from the garden and disposing of it properly.

Biological and habitat controls include:

  • Importing predators and parasitoids that prey on the pests of concern. Note that specific pests demand specific predators and predators need a food source to stay in the garden area. Generally, if you have managed your garden then the 'good' insects will naturally find their way to your garden and assist with pest control.
  • Maintaining a chemical-free habitat that is welcoming to beneficials and pollinators
  • Using resistant plant varieties means researching and selecting the best available hybrids that are resistant to likely pest challenges.

When nothing else works and damage levels warrant continued action, research the organic and manufactured chemical options for the specific pest in question. Insecticidal soaps are a good option for many sucking and chewing pests. Neem oil is similarly safe on food with no dangerous residues while killing or reducing pests, powdery mildew, and other fungal infestations. If all else fails and traditional pesticides are used, follow label directions carefully, use them minimally, and avoid spraying open flowers and applying them during the day when pollinator activity is highest.

The Harder Path is the Right Path

As is often the case, the more convenient approach — using neonicotinoids and other chemicals on a widespread basis in anticipation of pest problems — is seductive but ultimately harmful in the long term. Damage to pollinators, faster evolution of resistant pests and replacement of natural processes with chemicals are all costs that eventually have to be faced. The IPM approach requires more work and acceptance of a certain amount of pest damage. We must reduce and manage the use of neonicotinoids and other agricultural chemicals, as their long-term impact will be far more harmful than beneficial. Do it for the bees. Do it for the butterflies. Do it for the birds. Do it for you.

Top Ten Winter Bird Feeding Tips

White-Breasted Nuthatch

10. Make sure seed is accessible and dry. Hopper or tube feeders are good at protecting seed from wet weather. Sweep snow off of platform feeders, or clear a place on the ground where you can scatter seed for ground-feeding species such as sparrows, towhees, juncos, and doves.

9. Make a windbreak. Make a windbreak using your old Christmas tree or the remains of a brush pile. Consider planting shrubs next to your feeders where the birds can rest out of the wind and escape from predators. Consider clearing a small area of snow off the ground to scatter seed if it's too soft to support their weight.

8. Keep extra feeders for use in bad weather. We keep an extra-large-capacity tube feeder in the garage for use when nasty weather comes. It not only gives the birds another place to eat, which means more birds can eat at one time, but it also cuts down on our trips outside for refilling the feeders. Other extras to consider having: peanut feeder, suet feeder, satellite feeder (for the small birds to use), and a hopper feeder.

7. Scatter seed in sheltered places. Not all birds will venture to your feeder. Some species prefer to skulk in the thickets, brambles, and other secure places. For these species, consider scattering some seed (black-oil sunflower, sunflower bits, peanut bits, mixed seed) under your deck, in your hedges and bushes, or even along the edge of a wooded area. Dark-eyed juncos especially prefer to feed on food scattered on the ground along with tree sparrows and white-throated sparrows.

6. Put out high-energy foods such as suet, meat scraps, and peanut butter. Fat gives the biggest energy boost to winter birds and without enough energy to keep them going, many songbirds would not survive a cold winter night. Suet (the fat removed from processed beef), meat scraps, and peanut butter all provide fat to birds that eat them. If you don't have a suet feeder, use a mesh onion bag. Suspend it from a tree branch or iron feeder hook. To feed peanut butter, drill one-inch holes in a foot-long section of a small log. Insert a screw eye into one end of the log. Smear peanut butter into the holes and suspend the feeder from the screw eye. And, no, peanut butter will not stick to the roof of a bird's bill and choke it to death.

5. Use a birdbath heater wisely. A water heater can keep your birdbath open in the coldest of weather, which is good but place several large rocks in your bath so there is not enough room for a bird to bathe, but still plenty of places for a thirsty bird to get a drink. When the weather warms up you can remove the rocks and let your birds get on with their hygiene.

4. Offer mealworms in a heavy dish or small crock. Use a heavy dish so the wind can't blow the worms and dish away. This is a high protein snack that many birds enjoy and can be found in most feed stores. They are relatively expensive so use them sparingly on the coldest days or in the spring when an unexpected cold snap can leave migrants without much to eat.

3. Furnish your bird houses. Imagine you're a bird roosting in a nest box on a cold winter's night. Wouldn't it be nice to snuggle down into some dried grass or dry wood shavings in the bottom of the house? Layer three to four inches of clean dry meadow grass in the bottom of bluebird boxes after the last nesting of the summer. Wood shavings work well, too. Don't use sawdust, however; it can retain moisture once wet, which does not help the birds keep warm.

2. Plug the air vent holes in your bird houses with removable weather stripping. We use the claylike weather stripping that comes in a roll (Moretite is one brand) to plug the air vent holes in our bird houses. Good ventilation is necessary on a scorching summer day, but it's a real liability for birds seeking winter shelter. Think how cozy the birds will be in a well-sealed house.

1. Be ready for big changes in weather. If you keep abreast of the weather developments you'll know when bad weather is coming, and you'll be able to stock up on seed, suet, and other goodies. You can also be ready to take on some of the activities listed above. Conversely, when the weather breaks, take advantage by cleaning and disinfecting your feeders (one part bleach to nine parts hot water). Whatever you do, don't let yourself be caught totally unprepared for harsh winter weather.
