Rodents and insects chewing or cutting drip lateral pipes causing leaks, how to protect drip lines.
3 Answers
Rats, squirrels, and some insects chew drip laterals, often because the pipe holds cool moisture they are after in dry weather, which leaves you with leaks and uneven watering. Practical steps that help: keep the field bunds and channels clean of weeds and burrows where rodents nest, control the rodent population around the field, and where damage is heavy some farmers lay the laterals slightly buried or under mulch so they are less exposed, though buried lines need care so the emitters do not clog. Walk the lines regularly to spot leaks early and carry joiners and end caps to repair cuts quickly before the leak wastes water and pressure. If insects like crickets are the cause, manage them as part of normal field pest control. There is no single trick that stops it fully, so a mix of rodent control, clean bunds, quick repair, and protecting exposed pipe works best. For rodent control methods that are safe near your crop, check with your KVK.
Cleaning the burrows on my bunds cut the chewing right down. The rats were living in the weeds along the channel.
I keep a bag of joiners and end caps on the bike. A chewed pipe gets fixed in two minutes before it floods one spot.
