Small hive beetle oil tray results, week by week — sharing my counts since installing

Georgia, 22 years, and this is my first season running oil trays under screened bottoms on all eight hives instead of just the worst two. Since folks ask about SHB every August, here are actual numbers. Week 1: trays averaged 40+ beetles per hive, worst tray had 71. Genuinely shocking given I wasn't seeing many on inspections. Week 2: average dropped to about 18. Week 3: 9. This week (4): 5-6 per tray, and inspections show almost no beetles running on the top bars. Two observations. First, the trays reveal how many beetles a "clean-looking" hive is actually hosting — the bees chase them down through the screen and into the oil, which is the whole mechanism. Second, my two weakest hives had the HIGHEST counts, no surprise — strong colonies are still the real SHB control, trays are the assist. Cheap insurance either way. Vegetable oil, changed weekly, dead simple.
