FAQs
The most effective option is NZLA Grub+, an insecticide that provides long-lasting protection against grass grubs and caterpillars for up to six months. It uses the same active ingredient found in leading turf products but at a more affordable price.
One application of NZLA Grub Plus lasts up to six months, giving season-long control against grubs, caterpillars, and other lawn-damaging pests without the need for repeat treatments.
The ideal preventative times to apply NZLA Grub+ are October and March, which line up with peak grub and caterpillar activity in New Zealand lawns. Applying at these times gives your lawn season-long protection. If you missed a preventative application, you can also apply Grub+ at any stage during the growing season as a curative treatment whenever pests are active and causing visible damage.
The recommended application rate for NZLA Gru+ is 15ml per 100m², which provides up to six months of protection against grass grubs, caterpillars, and other soil pests. For a shorter protection period, you can apply a half-rate of 7.5ml per 100m², but this will only deliver around three months of control. For best results and season-long protection, the full 15ml rate is advised.
Yes. Once watered in and the lawn has dried, NZLA Grub Plus is safe for people, pets, and wildlife. It targets soil pests without leaving harmful residues on the grass.
Yes. NZLA Grub Plus provides broad-spectrum protection, controlling grass grubs, porina caterpillars, armyworm, and black beetle larvae – all of which can severely damage New Zealand lawns.
Spray Grub+ evenly over the lawn using a calibrated sprayer, then water it in with 6–10mm of irrigation. This moves the product into the soil where grubs are feeding. If treating for Porina leave irrigation for 24 hours so the product sits on the surface.
Yes – both products contain the same active ingredient. The difference is price and pack size. NZLA Grub+ delivers the same professional results at better value. Acelepryn only comes in a 750ml bottle our professional size comes in a 1L bottle so you receive 25% more product.
Light to moderate rain after application actually helps move Grub+ into the soil where pests are active. Heavy downpours immediately after spreading should be avoided if possible.
You can order NZLA Grub+ directly through the New Zealand Lawn Addicts online store, with fast nationwide shipping and support from a trusted lawn care team.
