Wireworm. 
Prevention and Remedies. 
The following notes are regarding the treatment to be adopted 
against Wireworm : — 
“ Numerous experiments both in the field and laboratory have 
been made to find out some way by means of which Wireworm may 
be killed in the ground. At present all experiments have failed 
except with bisulphide of carbon, which is too expensive to use over 
large areas as in field cultivation.* 
“ There are nevertheless certain measures we can take which will 
prevent and materially lessen these ground pests. 
“ Much good may be done in hop yards, gardens and nurseries by 
trapping the Click beetles. This may be done by laying small heaps 
of lucern, clover or sainfoin about on the ground, covering them over 
with tiles or pieces of board during May and June, and as long as 
the beetles are noticeable. They fly to these shelters, particularly if 
the ground is clean, and deposit their eggs, as well as shelter beneath 
the green material. These traps must be examined as often as 
possible, the beetles collected and the green stuff destroyed every ten 
days, and the ground beneath well beaten down so as to destroy any 
eggs that might be present. Boards and tiles might be placed 
beneath the bait so as to save any eggs from getting on the soil. As 
many as one hundred Click beetles have been taken from a single 
trap in a week. 
Certain patented substances are said to kill Wireworm in the soil, but they 
have yet to be found successful.
