Chafer Grub Treatment

Answered by Gavin Posted in Category Pest Control & Nature

Dear Gavin

I am just about to purchase some Chafer grub treatment. How long after the treatment do I need to wait until I can re-seed my lawn?

I was thinking of trying to buying some quick growing seed and do it this year.





Hello Alan


As soon as your nematodes have found their host (Chafer grubs in your case), death of the host usually occurs by 48hrs. Environmentalfactors (temperature, moisture, pest location, etc) will play apart in how effective the nematodes are, but if you can keep conditions favourable for at least 2 weeks then they should work well. These conditions should be stated on the application instructions, and will vary slightly depending on what specie of nematode you are using.

I would personally say you could apply your grass seed the following day after your nematode treatment as its going to take at least a few days to even begin to germinate, but certainly after a week or two.

Believe it or not I began my career as a cobbler, however, after 11 years in the trade I decided to pursue my boyhood dream of studying insects (this I had already been doing for much of my life!). Whilst studying towards this career change I applied for a part-time post in the entomology department at one of the UK's leading plant biological science research institutes. I was fortunate enough to secure the post, to which I have now occupied for 12 years full-time.
