Building A Moth Trap

The design is made from Aluminium and stainless just so that corrosion is not as much of an issue. Even the rivets, nuts and bolts and wire grips are made from these.

The Bulb is a Blacklight UV 20w bulb bought fron NHBS shop

This is one of the 3 vanes Mandy made to help direct the catch species into the containment area.

These are the three different size vanes to direct the catch species into the containment area. 

This is the outer collar again made from aluminium. Designed to be used in either convex or concave manor on top of the catchment tub.

This part is purely a safety measure. It will be bolted firmly to the unit and then hold the wiring in a fixed manner in case of any strain on the wire. This will eliminate the possibility of the electrical wiring being pulled out when live.

The jar will be a protection for the bulb against water and damage. It is a coffee jar that will fit inside the collar of the bulb holder.

This is the catchment tub. A large builders bucket with a very dense self adhesive tape applied for somewhere for the outer collar to rest. The bottom of the tub has lots of holes drilled in for drainage. Finally a fine mesh circular sheet (below) will fit in the base to stop the Moths from sitting in any water.

This is the bulb holder and wiring that has been bolted to the inner funnel with stainless steel bolts. Also note the cable clamp has been bolted to this unit to stop the wires from becoming detached for any reason.

This is the inner funnel. You can see that the bulb holder and glass protective collar is in place. The funnel is from a brewing supplies company with the bottom long funnel piece cut off.

This is the ES bulb holder that has been slightly modified with the plate on the bottom being made longer and two holes drilled in to make a secure fit by means of stainless steel bolts. The plate with the holes is also stainless. The holder is some sort of ceramic and heat resistant from a reptile supplies shop.

This is the inner funnel with the bulb holder and electric removed for spray painting to restrict light pollution through the funnel and into the catchment tub. I used a water based paint but I am finding that it easily gets rubbed off most likely due to the type of plastic of the funnel.

This is the inner funnel complete with bulb, bulb holder, bulb protective glass and wiring. As you can see the paint is already rubbing off in places.

The catchment tub with the self adhesive tape on the outer top edge. Just enough room left at the top to allow the outer collar to seat nicely.

This is the stainless steel mesh that sits inside the bottom of the catchment tub about 20mm of the base to allow water drainage and for the moths not to be sat in any water.

Self adhesive tape that is attached at the top of the catchment tub. This serves the purpose of allowing the outer funnel to be seated in position on the catchment tub
