Aphids, What are they
Aphids are tiny little bugs that have soft white/black/yellow/gray/green/pink bodies. The multiply like rabbits… rather, worse than rabbits as they can take over your whole garden if left unchecked.
There are many varieties, practically one for each plant type, and will eat the heck out of your plants. If your leaves are turning yellow or look kind of wilted/deformed, check the underside of the leaves. If the leaves are sticky, aphids were probably suckling your leaves.
As you can see in the image above, they’re pretty tiny. These are ones I found on a squash flower.
Prevention & Treatment
- Spraying with a strong enough stream to knock them off, rumor has it that once they’re knocked off they can’t find their way back
- Dust plants with DE, supposedly the small glass-linke crystals that are DE will cut and harm the aphids.
- I am trying this method currently. I’ve found that it’s rather difficult to “dust” the undersides of leaves where they supposedly like to be the most. I used a tiny scoop and kind of just tossed it up against the leaves hoping it would hit and spread. A lot of dust patches also ended up on top of leaves, I kind of softly beat the leaves like drums to get the dust to poof out and spread.
- Update: I’m not sure which method worked the best, but I used both of the above methods and within a week I didn’t find any aphids on my plants anymore.
- Sprays such as:
- Water / Soap / Oil mixture
- Garlic sprays, aphids don’t like the smell
- Dormant oil
- Attract beneficial bugs such as:
- Lady Bugs
- Parasitic Wasps
- Plant flowers nearby. This serves 2 purposes:
- Flowers will attract beneficial bugs
- Aphids like some flowers more than they like your vegetable plants and will go to them instead
- Flowers to plant:
- Nasturtium to attract beneficials and aphids
- Garlic and Chives to repell
