🐛 Common Pests in Phoenix
Aphids
Appearance: Small, soft-bodied insects (green, black, or brown) clustered on new growth and undersides of leaves.
Damage: Suck plant sap, causing curled or yellowed leaves. Secrete honeydew that attracts ants.
Treatment: Spray with water to dislodge. Use insecticidal soap or neem oil. Introduce ladybugs as natural predators.
Hornworms
Appearance: Large green caterpillars (3-4 inches) with white stripes and a horn-like tail.
Damage: Voracious eaters that can defoliate tomato plants overnight. Look for dark droppings on leaves.
Treatment: Hand-pick and destroy. Apply BT spray for organic control.
Cabbage Loopers
Appearance: Green caterpillars that "loop" when they crawl. Small white moths are the adults.
Damage: Chew irregular holes in leaves of cabbage family and other vegetables.
Treatment: Apply BT spray. Use row covers to prevent moths from laying eggs. Hand-pick when spotted.
Spider Mites
Appearance: Tiny red or brown specks on leaf undersides. May see fine webbing in severe infestations.
Damage: Leaves develop yellow stippling, eventually turning bronze or brown. Common in hot, dry weather.
Treatment: Spray forcefully with water. Use insecticidal soap or neem oil. Increase humidity around plants.
Whiteflies
Appearance: Tiny white flying insects that rise in a cloud when plants are disturbed.
Damage: Suck sap from leaves, causing yellowing and stunted growth. Secrete honeydew.
Treatment: Yellow sticky traps. Insecticidal soap or neem oil. Blast with water in early morning.
Leaf-Cutter Bees
Appearance: Black bees that cut perfect circles or ovals from leaf edges.
Damage: Cosmetic damage to leaves (circular notches). Don't harm plant health.
Treatment: Beneficial pollinators - no treatment needed! Damage is temporary and plants recover.
Cutworms
Appearance: Fat, soft gray or brown caterpillars that curl into a C-shape when disturbed. Active at night.
Damage: Cut seedlings and young plants at soil level overnight. Devastating to transplants.
Treatment: Place collars around seedlings (toilet paper rolls work well). Hand-pick at night with flashlight. Apply BT spray to soil surface.
Squash Bugs
Appearance: Brown or gray shield-shaped bugs about ½ inch long. Cluster on stems and leaf undersides.
Damage: Suck sap from pumpkins and squash, causing wilting and plant death. Very common in Phoenix.
Treatment: Hand-pick adults and eggs daily. Check undersides of leaves for bronze egg clusters and crush them. Use row covers on young plants.
Grasshoppers
Appearance: Large jumping insects, brown or green. Very common in Arizona during summer monsoons.
Damage: Chew leaves, stems, and fruits. Can completely defoliate plants. Worst in late summer.
Treatment: Use floating row covers. Apply Nolo Bait (organic grasshopper control). Hand-pick early morning when sluggish. Encourage birds.
Thrips
Appearance: Tiny (1-2mm) slender insects, yellow to brown. Hard to see without magnification.
Damage: Silvery stippling or streaking on leaves. Distorted growth. Common in Phoenix heat.
Treatment: Spray with insecticidal soap or neem oil. Blue sticky traps. Remove heavily infested plant parts.
Flea Beetles
Appearance: Tiny black beetles that jump like fleas when disturbed. Very small (1/16 inch).
Damage: Create tiny round holes in leaves (shot-hole appearance). Prefer young plants and seedlings.
Treatment: Use row covers on seedlings. Spray with neem oil. Diatomaceous earth around plant bases. Encourage healthy growth to outpace damage.
Stink Bugs
Appearance: Shield-shaped bugs, brown or green, about ½-¾ inch long. Emit foul odor when crushed.
Damage: Pierce fruits and vegetables causing dimpled or discolored spots. Tomatoes and peppers most affected.
Treatment: Hand-pick into soapy water (don't crush). Remove weeds where they overwinter. Use row covers on fruiting plants.
Cucumber Beetles
Appearance: Yellow-green beetles with black stripes or spots. About ¼ inch long.
Damage: Feed on pumpkin leaves, flowers, and young fruits. Can transmit bacterial wilt disease.
Treatment: Use row covers until flowering. Hand-pick adults. Yellow sticky traps. Neem oil spray. Remove plant debris promptly.
Sunflower Beetles
Appearance: Small brown or gray beetles (about 1/4 inch) with dark spots. Often found on sunflower leaves and stems.
Damage: Chew holes in sunflower leaves. Rarely severe enough to affect overall plant health or seed production.
Treatment: Usually not necessary - damage is cosmetic. Hand-pick if population is high. Neem oil spray for severe infestations.
Birds & Squirrels
Appearance: Various bird species (especially finches, jays) and squirrels attracted to ripening sunflower seeds.
Damage: Strip ALL seeds from sunflower heads in hours once seeds ripen. Can destroy entire harvest overnight!
Treatment: Prevention is key! Cover seed heads with bird netting, mesh bags, or paper bags when seeds start forming. Secure tightly. Harvest promptly when ripe.
🪴 Indoor Houseplant Pests
Fungus Gnats
Appearance: Tiny black flies (1/8 inch) that hover around soil surface. Larvae are small white worms in soil.
Damage: Adults are just annoying. Larvae feed on roots and organic matter in soil - can damage seedlings and weak plants.
Treatment: Let soil dry between waterings (gnats love moisture). Yellow sticky traps for adults. Add 1 inch sand/perlite layer on soil surface. Mosquito bits in water kills larvae. Avoid overwatering!
Mealybugs
Appearance: Small white cottony clusters in leaf crevices, stems, and undersides. Look like tiny cotton balls.
Damage: Suck plant sap causing yellowing, stunted growth, and leaf drop. Secrete honeydew (sticky residue). Can spread quickly!
Treatment: Isolate infested plant immediately! Dab with rubbing alcohol on cotton swab. Spray with insecticidal soap or neem oil. Repeat weekly for 3-4 weeks. Inspect all nearby plants.
Scale Insects
Appearance: Small brown or tan bumps stuck to stems and leaves. Look like oval shells (1/8 inch). Don't appear to move.
Damage: Suck sap causing yellowing leaves and weak growth. Secrete sticky honeydew. Heavy infestations weaken plant significantly.
Treatment: Scrape off with fingernail or old toothbrush. Wipe stems with rubbing alcohol. Spray with horticultural oil or insecticidal soap. Repeat treatment every 7-10 days for several weeks.
