Swarm Trap - May 5th 2024

Swarm summary: It was an unusual swarm trap season.🤣 My neighbors helped me see a swarm select a sycamore tree cavity, and 43 days later this bee nest swarms and selected my swarm trap 7 houses away. Flight vigor at the bee nest has since increased - the bee nest is a gift that keeps giving!

 

I was hoping for something else! 

• 9th March - I installed 4 swarm traps in my neighborhood
• active scouting began at two 40-liter swarm traps hanging from crepe myrtle limbs. Each swarm trap contained:
• 5x deep frames with plastic starter strips
• UV-reactive blue swarm trap entrance
• synthetically produced Nasonov pheromone
• 23rd March in the early afternoon - my traps are passed over as the bees selected a cavity in the sycamore tree trunk using a cut-off limb entrance and active scouting of swarm traps subsided
  
• 29th April - sycamore bee nest entrance was obscured by a huge bee beard - see the 2nd photo.
  

In a roundabout way, the moment I've been waiting for!   

• active scouting restarted at the two 40-liter swarm traps
• 5th May at 5:30PM - bees selected my backyard 40-liter swarm trap and the sycamore bee nest entrance is no longer obscured by a huge bee beard - a flight journey of 290 feet (88 meters) - see the 1st photo.
  
• over the next 6 days after dark, I moved the occupied swarm trap in 5 steps towards my empty backyard hive stand.  The after-dark move was made easier by leveling the next location during daylight hours.
  
• 13th May - I transferred 5 deep swarm trap frames to 8-frame equipment and moved the swarm lure to the 8-frame landing board. No smoking or brushing of bees was required. - see the 5th photo.

Swarm Trap - March 28th 2023

The moment I've been waiting for!

On February 20th, I set out two 40-liter swarm traps hanging from crepe myrtle limbs.   Each swarm trap contains:

• 5x deep frames with plastic starter strips
• UV-reactive blue swarm trap entrance
• synthetically produced Nasonov pheromone
  

In another 3 days, scout bees visited the swarm traps.  Though I waited for 33 more days before a swarm would select one of the swarm traps.

From mid-February to early March, Atlanta's maximum temperatures were warmer than expected. On February 21st, the high temperature was 21°F above maximum normals (1991-2020).   

On March 7th, pollen counts soared to 3937 - outdoor surfaces were covered with yellow pollen (pine, oak, sweet gum, hackberry, and birch).    Walking the dog, I discovered bees (mining, carpenter, and European honey) visiting crabapple tree flowers on my street - thanks to Trees Atlanta.

I set 4 hanging swarm traps on 3 properties in my neighborhood, each with: 

• UV-reactive blue swarm trap entrance
• synthetically produced Nasonov pheromone

2 of these traps are on my property and conveniently located where I can watch the swarm trap entrance and the behavior of scout bees from a window. See the video and read page 62 of Honeybee Democracy describing scout bees.

So far, the traps did not attract a swarm - my swarm trap hopes rest with a return to more normal temperatures after this week of frigid spring weather.

Impact of UV-Induced Blue Florescence Entrances concludes:

• UV-reactive blue swarm trap entrances nearly doubled the number of scout bees observed over the control
• Swarms selected the trap with the UV-blue entrance over the control 100% of the time

 method and materials:

• conducted from May to August in 2020 and 2021 in western New York
• 1.25 inch (3.2 cm) circular entrance hole
  
• 1.59 cubic ft (45 liter) cavity volume
• 4 frames without comb + 1 frame with some comb
  
• attached to a tree at a height of 8-10 feet
• 3 locations facing an open field with bee forage
• 2 traps per location 200 feet apart with a 3D printed trap entrance using 1) UV-reactive blue filament or 2) white filament (control)
  
• swarm lure spray applied weekly
• weather permitting, 1 location included scout bee counting between 11:30am-4:00pm

40-liter Swarm Trap

 

On May 9th, the front porch video captured scout bees at my new 40-liter swarm trap.  Ultimately this trap was not chosen by the swarm.  In the still photo, I reused a hanging location for the 40-liter trap where a 8-frame trap successfully attracted a swarm on May 10th.

Each 40-liter trap contains:

• 4x deep frames with either foundation or plastic starter strips
• 1x deep frame of dark comb
• 1x slow-release tube containing lemongrass oil

Two 40-liter traps were sourced from one sheet of 4 by 8 foot 1/2 inch birch plywood.   Each trap required the following pieces:

• 2x front (or back) pieces - 19 5/8 inch by 17 1/4 inch
• 2x side pieces - 7 7/8 inch by 17 1/4 inch with 5/8 inch by 1/4 inch rabbit for frame hanging
• 1x top piece - 19 5/8 inch by 8 7/8 inch
• 1x bottom piece - 18 5/8 inch by 7 7/8 inch

Additional materials:

• 1x circular Betterbee hive portal (optional)
  
• 1x 1 inch bolt and wing nut (optional)
• 2x fender washers (optional)
• Aluminum Roll Flashing cut with a Dremel Fiberglass Reinforced Cut-Off Wheelcutting disk
  
• Titebond II wood glue and clamps 

swarm trap and capture - May 2021

On March 7th, I set out two 8-frame swarm traps hanging from crepe myrtle limbs.  I also prepared two hive stands as 8-frame swarm traps.   Each trap contains:

• 7x deep frames with either foundation or plastic starter strips
• 1x deep frame of dark comb
• 1x slow-release tube containing lemongrass oil

Immediately the traps were visited by scout bees, though I waited 64 days before a swarm would select one.  Here I share my 2021 swarm experience - so far.

On May 3rd, I set out two 40 liter (2441 cubic inch) swarm traps which contain similar elements as above except that there are just 5x deep frames in the top half and considerable volume (space) without frames beneath this tall and narrow configuration.   I'll share more details and photos of the 40 liter trap in future blog posts. If you are keeping count, I now have set out six swarm traps.

On May 6, the Nextdoor website mentioned that a swarm had landed at gusto! on Ponce, a restaurant near Clermont Hotel.   Last year I used Nextdoor information to locate and capture two swarms.  Nextdoor continues to be my main source of social media knowledge of local swarms.

On May 9 mid-afternoon, active scouting began at one swarm trap and by late afternoon two other traps had active scouting.  

On May 10 noon, all six swarm traps have scouts with the most intense active scouting focused at one hanging swarm trap.  I went for a 30 minute dog walk and in that short time I missed the swarm arrival.  At 3:30 I captured the attached video of bees completing their move into the 8-frame hanging swarm trap.

On May 11 dawn, I lowered the hanging swarm trap, closed its bottom entrance and set the left-right leveled trap onto a 3-step A-frame ladder.   In following days, I moved this 'ladder + trap' configuration at dawn 3 meters (10 feet).  I repeated these moves until I reach the desired backyard hive stand location.  Moving the trap created bee confusion and including a nearby closed patio umbrella in the move seemed to reduce this confusion.  On May 19, I transferred deep trap frames into a deep 8-frame box with a screened bottom board.   Every frame contained bees building new comb with the majority of bees found on the frame of dark comb.
