Flea Beetle across the plant library
28 of the 505 plant guides in this library name flea beetle among their pests. Every one is listed below, linked to its guide and grouped by the kind of plant it is, so you can see at a glance which corners of a garden it turns up in.
This is the library read down a column instead of across a row. Each plant guide names its own pests; nobody publishes the other view — which of the plants you actually grow share one, and whether the timing they record agrees.
The 28 plants that list flea beetle
Grouped by plant type. Where the library attached a note to the entry — “rare”, “on seedlings”, “in wet clay” — that note is printed next to the plant, verbatim, because two plants can name the same pest and mean opposite things by it.

Shared timing — and where it doesn’t agree
7 of the 7 recorded flea beetle timings in this library contain that exact phrase. That is a count of what the guides say, not a recommendation — the entries themselves are below, unedited, and the label on whatever you use governs the rest.
Quoted verbatim from the spray-timing fields of the guides that name flea beetle. Another 15 of the 28 record a program aimed at a different problem; those stay on their own guides.

Timing only — the label is the law
This page reports when the guides in this library say to watch for flea beetle and when a treatment is worth considering. It is not a recommendation to apply any product. Read and follow the product label before you spray — under federal law the label is the legal instruction, and using a pesticide against it is illegal.
- Check the pre-harvest interval. Every product that’s cleared for an edible crop sets a minimum number of days between spraying and picking. Find it on the label before you spray anything you intend to eat.
- Check the re-entry interval before you or anyone else works in the treated area again, and use the protective equipment the label names.
- Confirm the product is registered for your crop in your state. This page groups many different crops together, and a product legal on one of them is not legal on all of them — state registrations differ too. Your state pesticide agency or local extension office can confirm both.
- Rates and mixing instructions come from the label, never from us. We don’t publish them because they differ by product and formulation.
