3 Use IPM! Integrated Pest Management Monitor for pests and ‘pest-conducive’ conditionsPrevent Pests: Use sanitation, maintenance and good horticultural practicesDetermine your Threshold: Is it really a pest? How many is too many?Use multiple pest control methods that eliminate pest access to food, water, shelter.Keep records: use a garden notebook
4 Elements of Garden IPM Know your enemy. Identify pests and good bugs. Send samples to UM Pest Management Office or local Extension office for ID.Visit or Bugguide.net or other websites to ID pests and learn their food, water, shelter requirementsAvoid pestsUse barriers (such as row covers, fence, bird netting)Rotate crop families to new areas yearly
5 Elements of Garden IPM Use Good horticultural practices Select right plants for right placesChoose pest-resistant, disease-resistant cultivarsProvide plants with optimal plant nutrition, right amt of water, optimal plant spacing.Protect and Encourage Natural EnemiesSpare the (pesticide) spraysDiverse plantings including season-long offering of plants with flat, open flowers to provide nectar for small beneficial insects.
6 Physical IPM Methods Mulching Sanitation Can suppress weeds, conserve moisture, provide habitat for natural enemiespull mulch away from the trunk to decrease pest/ disease potentialSanitationRake leaves to reduce diseasePrune away diseased plant tissue
11 Common Garden Pests and Solutions Striped cucumber beetleTransplant cukes, squash, zucchini, pumpkins instead of direct seedCover with spun-bonded row cover (example Remay, Typar) until flowering.
12 Lily Leaf Beetle Plant daylilies instead of true lilies Hand pick beetles and larvae. Squish eggs.Space plantings to allow good sunlight penetration.Least-risk pesticide: neem (example Neemix, Bioneem) if needed.
13 Note: Winsome fly eggs. This beetle has been attacked by a natural enemy! Japanese BeetleSelect non-preferred shrubs and trees (avoid linden, roses, crabapples, grapes, raspberries)Hand-pick beetles (but leave the parasitized beetles)Cover susceptible plants with protective nettingGrub Control: Heterorhabditis bacteriophora (Hb) nematodes. purchase on-line, water them in.Avoid Japanese beetle traps
14 Biological IPM Methods Rely on Natural Enemies Winsome fly eggsWinsome Fly: natural enemy of Japanese Beetle
15 Paper and Straw MulchSuppresses WeedsProvides Habitat for Natural EnemiesKeeps Soil from Drying Out
16 Slugs and Snails Control weeds Keep grass mown low or consider gravel strip around gardensTraps (beer cups or wooden boards)Copper foil ribbon around raised beds or pots.
17 Diseases Select resistant varieties Select good site (water drainage, good soil, full sun, air movement)Maintain good plant spacingMulch prevents rain-splash of soil-borne diseases‘Rogue-out’ diseased plantsEnsure plants get the right amount of sun, water, and nutrition.
18 Avoid Late Blight Plant only certified potato seed Destroy any volunteer potatoesPlant only healthy tomato seedlingsBag infected plants. Have disease confirmed by Extension. Dispose of infected plant tissue. Don’t compost
19 What about Indoor Pests? Prevent PestsSanitation: don’t give pests food, waterKeep them out: repair screens, doors, cracks, crevicesRemove PestsVacuum, wash, comb, discardUse Physical Control Methodsheat or freeze infested materialsswat them!Use traps (flies, mice, moths)
20 FleasTreat the pet!Bathe it and flea-comb oftenVacuum a lot. Rugs, upholstered furniture, floors. Put vacuum bag in freezer after each use.Launder pet beddingSpot-on pet treatments (eg Frontline) are safer than flea powders, shampoos, sprays, bombs.
21 Mice Keep food (human, pet, bird) in pest-proof container. Empty garbage/compost daily. Use pest-proof garbage cans.Seal cracks in foundation, exterior walls, under doors, etcTrap them out
22 Bed Bug Interceptor under bed legs Bed BugsWhen TravellingInspect hotel bed. Look for blackish spots and/or reddish-brown bugs (poppy-seed to apple-seed sized) along mattress seams.Don’t put suitcase on bed or floor. Inspect suitcase upon return home. Look in crevices/seams/pockets for bugs.Avoid second-hand furniture.Home InfestationSystematically search and vacuum every crack/crevice/seam in bedroom. Eggs don’t vacuum - scrape them up. Steam-clean carpet.Seal mattress in zippered bedbug-proof mattress cover. Place traps under bed legs.Hire reputable pest control company to inspect and treat (some use trained dogs and heat treatment instead of pesticides).Find resources atBed Bug Interceptor under bed legs
23 Carpenter AntsLocate Nests: Look for course sawdust next to wood, or oval holes about 1/8” wide, or put out food (try a milk/sugar paste) and follow them to nest or entry sites.Locate and seal ant entry sites such as gaps under doors or around windows and cracks in the foundation.Clean up and seal up food that attracts ants.Do carpentry to remove ant-infested wood.Ant baits such as those containing liquid borax or boric acid, placed near indoor ant activity is often effective.Carpenter ant-damaged wood
